# ProgressDialog Properties

Control progress dialog box appearance and behavior

Progress dialog boxes indicate that an operation is in progress by displaying an animated progress bar. The uiprogressdlg function creates a progress dialog box and sets any required properties before displaying it. By changing property values of a progress dialog box, you can modify certain aspects of its appearance and behavior. Use dot notation to refer to a specific object and property:

fig = uifigure; d = uiprogressdlg(fig); d.Value = .25;

## Text and Styling

expand all

Message, specified as a character vector, cell array of character vectors, or string array. The message displays within the dialog box, above the progress bar.

To display multiple lines of text, specify a cell array of character vectors or a string array. Each element in the array corresponds to a line of text. Hard breaks within each element, such as '\n', create additional lines of text.

Example: d = uiprogressdlg(uifigure,'Message','Calculating result.');

Title, specified as a character vector or a string scalar. The title displays in the title bar of the dialog box.

Example: d = uiprogressdlg(uifigure,'Title','Calculating');

Predefined or custom icon, specified as a character vector, string scalar, or truecolor image array.

#### Predefined Icon

This table lists the values to specify the predefined icons.

ValueIcon
'' (default)No icon added.
'question'

'info'

'success'

'warning'

'error'

#### Custom Icon

Specify a custom icon as one of these values:

• A character vector or string scalar that specifies the file name of an SVG, JPEG, GIF, or PNG image that is on the MATLAB® path. Alternatively, you can specify a full path to the image file.

Dialog text interpreter, specified as:

• 'none' — Display literal characters.

• 'tex'— Interpret text using a subset of TeX markup.

• 'latex'— Interpret text using a subset of LaTeX markup.

• 'html'— Interpret text using a subset of HTML markup.

#### TeX Markup

Use TeX markup to add superscripts and subscripts and to include special characters in the text.

Modifiers remain in effect until the end of the text. Superscripts and subscripts are an exception because they modify only the next character or the characters within the curly braces. When you set the interpreter to 'tex', the supported modifiers are as follows.

ModifierDescriptionExample
^{ }Superscript'text^{superscript}'
_{ }Subscript'text_{subscript}'
\bfBold font'\bf text'
\itItalic font'\it text'
\slOblique font (usually the same as italic font)'\sl text'
\rmNormal font'\rm text'
\fontname{specifier}Font name — Replace specifier with the name of a font family. You can use this in combination with other modifiers.'\fontname{Courier} text'
\fontsize{specifier}Font size —Replace specifier with a numeric scalar value in point units.'\fontsize{15} text'
\color{specifier}Font color — Replace specifier with one of these colors: red, green, yellow, magenta, blue, black, white, gray, darkGreen, orange, or lightBlue.'\color{magenta} text'
\color[rgb]{specifier}Custom font color — Replace specifier with a three-element RGB triplet.'\color[rgb]{0,0.5,0.5} text'

This table lists the supported special characters for the 'tex' interpreter.

#### LaTeX Markup

Use LaTeX markup to format and display mathematical expressions, equations, and special characters. Use dollar symbols around the marked up text. For example, use '$\int_1^{20} x^2 dx$' for inline mode or '$$\int_1^{20} x^2 dx$$' for display mode.

The displayed text uses the default LaTeX font style. You can use LaTeX markup to change the font style.

MATLAB supports most standard LaTeX math mode commands. For more information, see Supported LaTeX Commands.

#### HTML Markup

Use HTML markup to display links and customize font styles.

The interpreter supports a subset of HTML markup. As a general guideline, the interpreter supports text-related tags and styles. Unsupported tags and styles are ignored.

This table lists the supported elements and element attributes.

## Progress

expand all

Fraction complete, specified as a number between 0 and 1. The progress bar reaches its full length when the value is 1. Change Value at different points in your code to provide a visual indication of progress in the running app.

Data Types: double

Show percentage, specified as 'off' or 'on', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

Set this property to 'on' to display the fraction complete as a percentage in the dialog box.

Indeterminate progress, specified as 'off' or 'on', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

Set this property to 'on' to provide an animated bar without any specific progress information. This animation is useful when you do not know how long a calculation will take.

To prevent indeterminate progress bars from displaying indefinitely, call the close function after completing your calculations.

## Interactivity

expand all

Allow cancellation, specified as 'off' or 'on', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

A value of 'on' displays a cancel button in the dialog box. You can customize the button label by specifying the CancelText property.

When you allow cancellation, you must check the value of the CancelRequested property, and call the close function when the value is true. Otherwise, the dialog box displays indefinitely.

Cancel button text, specified as a character vector or string scalar. This property has an effect only when the Cancelable property is set to 'on'.

Example: d = uiprogressdlg(uifigure,'Cancelable','on','CancelText','Stop')

Cancel requested, specified as true or false. Use this property when Cancelable is 'on', and you want to know whether the user clicked the cancel button. This property is false until the user clicks the cancel button, then the value changes to true.
