Push Button

Change parameter or variable value using button with customizable appearance

Since R2021b

• 

Libraries:
Simulink / Dashboard / Customizable Blocks

Description

The Push Button block changes the value of the connected variable or parameter and executes MATLAB^® code in response to a click (immediate release of the pointer) or a press (delayed release of the pointer). You can specify different code for the click than the press. When you press the button, the code either executes after a time span you specify or at time intervals you specify. When you use the Push Button block in the Customizable Blocks library, you can modify the appearance of the block so it looks like a button in a real system. Use the Push Button block with other dashboard blocks to create an interactive dashboard to control your model.

To push the virtual button during simulation, click the Push Button block. To push the virtual button when the simulation is not running, click the Push Button to select the block, and then click the Push Button block again to push the button. While you press down your pointer for the click, the button is pushed. When you release your pointer, you release the button.

You can use callback functions to specify what you want the button to do:

• PressFcn functions run while the button is pushed. You can configure the button to run the PressFcn function only once while the button is pushed, or you can specify a repeat interval. To run the function only once, specify a repeat interval of 0.

• ClickFcn functions run when you release the button.

You can configure the button to stay pushed when you release your pointer by setting the Button Type to Latched. When you choose the latched button type:

• To latch the button, click the button.

• To unlatch the button, click the button again.

The PressFcn function runs while the button is latched. The ClickFcn function runs once when you latch the button and once when you unlatch the button.

You can use states to specify how the appearance of the Push Button block changes when you interact with the button:

• While you push the button, the block is in the Pressed state.

• When the button is latched and you are not pushing it, the block is in the Latched state.

• When the button is latched and you are pushing it, the block is in the Latched and Pressed state.

• When the block is not in any of these three states, it is in the Default state.

A state pairs pointer actions with:

• A state label

• A state icon

• A state image

The Pressed, Latched, and Latched and Pressed states also pair pointer actions with the On Value of the Push Button block. When you enter one of these states from the default state, the On Value is assigned to the Simulink^® component to which the Push Button block connects and stays assigned until the button returns to the Default state. If you release the button before a full time step elapses, the On Value is assigned to the component for the duration of the subsequent time step.

Note

• Double-clicking a connected Push Button block during simulation or after clicking the block does not open the Block Parameters dialog box. To open the Block Parameters dialog box, press Shift, then double-click the block.

• Clicking a connected Push Button block during simulation both selects the block and pushes the button. To select the block without pushing the button, press Shift, then click the block.

Customize Push Button Blocks

When you add a Push Button block to your model, the block is preconfigured with a default design. You can use the block with the default design or customize the appearance of the block.

To customize the appearance of the block, use design mode. After selecting the block, you can enter design mode in one of three ways:

• In the Simulink Toolstrip, on the block-specific tab, under Design, click Edit.

• In the Property Inspector, on the Design tab, click Edit.

• Pause on the ellipsis that appears over the block and click the Edit Custom Block button .

In design mode, you can use the toolbar above the block to customize the push button. To access additional customization options or to enter exact values for design settings, use the Design tab in the Property Inspector.

When you customize a Push Button block, you configure the block appearance for each state. When you configure the Block Type as Momentary, the block has two states. When you configure the Block Type as Latch, the block has four. To select a state to customize, use the drop-down list in the toolbar. Alternatively, on the Design tab, select the States component and then select from the Select State list.

Design Mode Actions that Customize the Selected State

Action	Available in Toolbar	Available in Design Tab
Specify the On Value for the Pressed, Latched, and Latched and Pressed states.	No	Yes
Specify the state label text.	No	Yes
Specify the color and opacity of the state label text.	Yes	Yes
Upload a state image.	Yes	Yes
Upload a state icon.	Yes	Yes
Change the size of the state image and state icon.	No	Yes
Change the position of the state label, state image, and state icon.	No	Yes

In addition to customizing the block design using the toolbar and Design tab, you can also resize and reposition components interactively in the canvas. To resize a component specific to a state, such as the state image, select the state in the toolbar, and then resize or reposition the component.

Design Mode Actions that Apply to All States

Action	Available in Toolbar	Available in Design Tab
Upload a background image.	No	Yes
Set a solid background color.	No	Yes
Upload a foreground image.	No	Yes

When you finish editing the design, to exit design mode, click the X in the upper right of the canvas.

Connect Dashboard Blocks

Dashboard blocks do not use ports to connect to model elements. To connect a dashboard block, use connect mode. To enter connect mode on an unconnected block, pause on the block you want to connect and click the Connect button . To enter connect mode on a connected block, select the block, pause on the ellipsis that appears (…), and in the action menu that expands, click the Connect button.

To connect a control block to a parameter in your model or to change the connection of a control block, enter connect mode. Select the block to whose parameter you want to connect. From the list that appears, select the parameter to which you want to connect. Then, pause on the dashboard block and click the Done Connecting button .

The control block cannot connect to a parameter defined by a variable until you update the model diagram. To connect to a parameter defined by a variable or to modify the value of a variable that defines the value of a connected parameter when the simulation is not running, update the model diagram by pressing Ctrl+D.

You can connect to a parameter with a scalar value or to an element of a matrix or structure. For more information, see Connect Dashboard Blocks to Simulink Model.

You can also connect dashboard blocks to a Stateflow^® chart. For more information, see Connect Dashboard Blocks to Stateflow (Stateflow).

This animation shows how to connect the Push block to your model.

Parameter Logging

Tunable parameters connected to dashboard blocks are logged to the Simulation Data Inspector, where you can view the parameter values along with logged signal data. You can access logged parameter data in the MATLAB workspace by exporting the parameter data from the Simulation Data Inspector by using the UI or the Simulink.sdi.exportRun function. For more information about exporting data using the Simulation Data Inspector UI, see Export Data to Workspace or File. The parameter data is stored in a Simulink.SimulationData.Parameter object, accessible as an element in the exported Simulink.SimulationData.Dataset.

Examples

Design Custom Buttons

Design buttons using the customizable Callback Button and Push Button blocks.

• Open Model

Limitations

• Except for the Dashboard Scope block and the Display block, dashboard blocks can only connect to real scalar signals.

• You cannot use the Connection table in the Block Parameters dialog box to connect a dashboard block to a block that is commented out. When you connect a dashboard block to a commented block using connect mode, the dashboard block does not display the connected value until the you uncomment the block.

• Dashboard blocks cannot connect to model elements inside referenced models.

• When you simulate a model hierarchy, dashboard blocks inside referenced models do not update.

• Dashboard blocks do not support rapid accelerator simulation.

• When you connect a dashboard block to a variable or parameter during simulation, the data for that variable or parameter is not logged to the Simulation Data Inspector. To log variable and parameter data to the Simulation Data Inspector, connect the dashboard block to the variable or parameter prior to simulation.

• When you simulate a model in external mode with the Default parameter behavior set to Inlined, dashboard blocks can appear to change parameter and variable values. However, the change does not propagate to the simulation. For example, Gain blocks display changes made to the Gain parameter using the dashboard blocks, but the Gain value used in the simulation does not change.

Parameters

Use the Property Inspector and the Block Parameters dialog box to specify the values of the block parameters. To set the core parameters of the dashboard block, use the Block Parameters dialog box or the Parameters tab in the Property Inspector. To customize the block, use the Design tab in the Property Inspector. To open the Block Parameters dialog box for a block, double-click the block. To open the Property Inspector, on the Modeling tab, under Design, select Property Inspector.

Parameters

To set the core parameters of the dashboard block, open the Property Inspector and click the Parameters tab.

Connection

Connection — Block parameter value to connect

parameter value connection options

Dashboard blocks do not use ports to connect to model elements. To connect dashboard blocks to parameter values in your model, use connect mode, the Simulink Toolstrip, or the Connection table in the Block Parameters dialog box. To open the Block Parameters dialog box from the Property Inspector, to the right of Connected to, click Connect or Change. You can connect to a parameter with a scalar value, or to an element of a matrix. For information about connect mode and how to connect using the toolstrip, see Connect Dashboard Blocks to Simulink Model.

To connect a control block to a parameter with a scalar value or change the connection of a control block to a parameter with a scalar value using the Connection table:

1. Select the block.

2. To connect the block, in the Property Inspector, on the Parameters tab, click Connect. To change the connection of the block, click Change instead.

3. Select the block to whose parameter value you want to connect.

4. In the table, select the parameter to which you want to connect.

5. Click Apply.

The control block cannot connect to a parameter defined by a variable until you update the model diagram. To connect to a parameter defined by a variable or to modify the value of a variable that defines the value of a connected parameter when the simulation is not running, update the model diagram by pressing Ctrl+D.

You can also connect dashboard blocks to a Stateflow chart. For more information, see Connect Dashboard Blocks to Stateflow (Stateflow).

Programmatic Use

To programmatically connect a dashboard block to a tunable parameter, use a Simulink.HMI.ParamSourceInfo object. The Simulink.HMI.ParamSourceInfo object contains four properties. Some properties apply to connecting dashboard blocks to parameters defined by values, and some apply to connecting dashboard blocks to parameters defined by variables. Not all fields have a value for a connection because a given dashboard block connects to either to a parameter defined by a value or to a parameter defined by a variable.

Block Parameter: Binding

Type: Simulink.HMI.ParamSourceInfo

Default: []

Main

Button Type — Button response to click

Momentary (default) | Latch

Specify how the block responds to a click.

• Momentary — The button changes state only while pressed. When you release the click, the button returns to its default state.

• Latch — The button latches the state change when clicked. The button remains in the pressed state until you click it again.

When you configure Button Type as Momentary, the block has these states:

• Default — Default state for the block when it is not pressed

• Pressed — Block state when the block is pressed

When you configure Button Type as Latch, the block has these states:

• Default — Default state for the block when it is not pressed.

• Pressed — Transitional state when you press the button while it is in the Default state. The block transitions to the Latched state when you release the click.

• Latched — Latched state for the block when it is not pressed.

• Latched and Pressed — Transitional state when you press the button while it is in the Latched state. The block transitions to the Default state when you release the click.

Programmatic Use

Block Parameter: ButtonType

Type: string or character array

Value: 'Momentary' | 'Latch'

Button Text — Button label text

'Button' (default) | string | character array

Specify the text for the button label. The label is applied to the button for the state that is selected in the Select State section of the States component on the Design tab.

Programmatic Use

Specify the ButtonText parameter for the block as a string or a character vector.

Block Parameter: ButtonText

Type: character vector | string

On value — Value assigned to connected parameter when button is pressed or latched

1 (default) | scalar

The value assigned to the connected block parameter when the button is pressed or latched.

Tip

Use the Block Type parameter to configure how the block responds to a click:

• Momentary — The button applies the On Value only while you press it.

• Latch — The button latches the state change when you click it and applies the On value until you click it again.

Programmatic Use

Specify the OnValue parameter for the block as a scalar value that is formatted as a string or a character vector.

Block Parameter: OnValue

Type: string or character array

Values: scalar

Default: '1'

Label — Position of label displaying name of connected element

Hide (default) | Bottom | Top

You can display the name of the element to which the dashboard block connects in a label positioned at the top or bottom of the block, or you can hide the label. If you want the label to be visible, specify the position of the label. If you do not want the label to be visible, select Hide.

Note

When the dashboard block is not connected to an element, the label is blank.

Programmatic Use

Block Parameter: LabelPosition

Type: character vector

Values: 'Hide' | 'Bottom' | 'Top'

Default: 'Hide'

Lock Aspect Ratio — Option to maintain block aspect ratio

on (default) | off

Select this parameter to maintain the aspect ratio when resizing the block in the Simulink canvas.

When the aspect ratio is locked, adding a new background image changes the aspect ratio of the block to match the aspect ratio of the background image. When the aspect ratio is unlocked, adding a new background image does not change the aspect ratio of the block, but instead changes the aspect ratio of the background image to fit the size of the block.

When the aspect ratio is locked, pressing the Shift key while resizing a block temporarily unlocks the aspect ratio. When you release the Shift key, the aspect ratio locks. When the aspect ratio is unlocked, pressing the Shift key while resizing a block temporarily locks the aspect ratio. When you release the Shift key, the aspect ratio unlocks.

Callbacks

ClickFcn — MATLAB code that executes in response to click

Version History

Introduced in R2021b

R2025a: Select dashboard block and open Block Parameters dialog box during simulation

When a Simulink block from the Dashboard or Customizable Blocks library is active, you can interact with the gadget the block represents. For example, you can push a button or flip a switch. When a block is inactive, you can only interact with the block. For example, you can move or resize the block. By default, all blocks from the Dashboard and Customizable Blocks libraries are active during simulation. Blocks promoted to a dashboard panel are also active when the panel is open in its own window or docked and unlocked. Callback Button blocks for which at least one of the callbacks triggered by pushing the button has a nonempty value are always active. To interact with the gadget represented by an inactive block, you can temporarily activate a block by clicking the block. When you deselect the block, the block becomes inactive again.

Clicking an active Callback Button block or an active block from the Dashboard or Customizable Blocks library that is connected to a parameter or variable value both selects the block and interacts with the gadget the block represents. For example, clicking an unselected active connected Push Button block both selects the block and pushes the button. Starting in R2025a, you can select the block without interacting with the gadget by pressing Shift and then clicking the block. Similarly, you can open the Block Parameters dialog box by pressing Shift and then double-clicking the block.

R2024b: Unlock dashboard block aspect ratio with keyboard

If the aspect ratio of a block from the Dashboard library is locked, you can temporarily unlock the aspect ratio by pressing Shift. When you release the Shift key, the aspect ratio locks.

If the aspect ratio is unlocked, pressing Shift temporarily locks the aspect ratio. When you release the Shift key, the aspect ratio unlocks.

R2024a: Deploy dashboard panel as web app or standalone desktop app

With a Simulink Compiler™ license, you can now deploy a dashboard panel, packaged with the model to which the panel connects, as a standalone desktop app or as a web app. You can use the app to operate the controls and monitor the displays on the panel independent of Simulink.

To learn how to deploy panels, see Deploy Dashboard Panel as App.

R2024a: Dock dashboard panels

Starting in R2024a, you can dock dashboard panels to the Simulink Editor window. You can use the docked panel to monitor signals and control parameters during simulation without covering the model diagram in the canvas.

For more information, see Dock Panels.

R2023b: Open panel in new window

Starting in R2023b, you can open a dashboard panel in a new window. To do so, select the panel and pause on the ellipsis that appears. In the action menu that expands, click Open In New Window .

You can minimize and restore the new window containing the panel separately from the model window. From the panel window, you can run, pause, stop, and step through the simulation. In the panel window, you can edit the panel and the blocks it contains.

To return the panel to the model canvas, in the panel window toolstrip, click Open in canvas .

For more information about opening a panel in a new window, see Open Panels in New Window.

R2023a: Persistent panels tab in Simulink Toolstrip

When you add a dashboard panel to a model, the Panels tab appears in the Simulink Toolstrip and shows options for managing and editing panels.

Previously, the Panels tab was only visible when a panel was selected. Starting in R2023a, the Panels tab stays visible when no panel is selected.

The Panels tab also contains these new options:

• You can add an empty panel.

• You can rename the selected panel.

• You can hide the selected panel.

R2022b: Undo and redo support for customizable dashboard blocks in panel

Starting in R2022b, you can undo and redo the changes you make to customizable dashboard blocks that are in a panel.

To undo or redo a change:

1. Click the panel or a block in the panel.

2. Press Ctrl+Z to undo the change, or press Ctrl+Y to redo the change.

Note

The keyboard shortcuts are based on Windows^®. On a Mac, press command (⌘) instead of Ctrl.

R2022b: Toolstrip support for panels

Starting in R2022b, you can use the Simulink Toolstrip to manage and edit panels and the dashboard blocks that they contain.

When you click a dashboard block in a panel, the toolstrip tab for the block appears. For example, when you click a Circular Gauge block, the Gauge tab appears in the toolstrip.

When you click a panel, the Panel tab appears in the toolstrip. The tab provides these options:

• Manage the visibility of panels in the model.

• Fit all unhidden panels within the current view.

• Collapse the selected panel.

• Customize the size and the contents of the panel.

• Set a custom background image for the selected panel.

• Add a new tab to the selected panel.
