Remove style from UI component

Syntax

Description

removeStyle([comp](#mw%5F4af699b3-60a3-45b5-96d8-d10a92c49257)) removes all styles created with the uistyle function from the specified table, tree, list box, or drop-down UI component. To determine which styles are on comp and available to remove, query the value ofcomp.StyleConfigurations.

example

removeStyle([comp](#mw%5F4af699b3-60a3-45b5-96d8-d10a92c49257),[ordernum](#mw%5F43b79cfc-8cfe-46be-9d8e-8dd213407b19)) specifies which style to remove. Specify a style based on the order in which it was added. The property comp.StyleConfigurations lists styles in the order that they were added.

First, add two styles to a tree.

fig = uifigure; fig.Position = [100 100 250 350]; t = uitree(fig); n1 = uitreenode(t,'Text','Fruits'); n11 = uitreenode(n1,'Text','Banana'); n12 = uitreenode(n1,'Text','Cherry'); n2 = uitreenode(t,'Text','Vegetables'); n21 = uitreenode(n2,'Text','Broccoli'); n22 = uitreenode(n2,'Text','Lettuce'); expand(t)

s1 = uistyle('FontColor',[0 0.4 0.7]); s2 = uistyle('FontColor',[0.1 0.5 0.1]);

addStyle(t,s1,'level',2); addStyle(t,s2,'node',[n2 n21 n22]);

A tree with nodes listing fruits and vegetables. The Banana and Cherry nodes are blue, and the Vegetables, Broccoli, and Lettuce nodes are green.

Then, remove both styles to revert the tree to its default appearance.

A tree with nodes listing fruits and vegetables. All node font is black.

Add multiple styles to a table UI component, and then remove some of them.

First, create a table UI component and add styles to different parts of it.

fig = uifigure; fig.Position = [500 500 720 230]; uit = uitable(fig); uit.Data = randi([-20,20],7); uit.Position = [20 30 680 185];

[row,col] = find(uit.Data<0);

s1 = uistyle; s1.BackgroundColor = 'cyan'; addStyle(uit,s1,'column',[1 3 5])

s2 = uistyle; s2.FontColor = 'red'; s2.FontWeight = 'bold'; addStyle(uit,s2,'cell',[row,col])

s3 = uistyle('BackgroundColor','green'); addStyle(uit,s3,'row',[3 4])

addStyle(uit,s1,'column',7)

Table UI component with 7 columns and 7 rows. The negative-valued data is displayed in bold red text. Cells in rows 3 and 4 and between columns 1 and 6 are green. The remaining cells in columns 1, 3, and 5 are cyan. All of the cells in column 7 are cyan.

Now, remove the row and column styles. First, query the value of theStyleConfigurations property for the table.

ans=4×3 table Target TargetIndex Style
______ _____________ ___________________________

1    column    { 1x3 double}    [1x1 matlab.ui.style.Style]
2    cell      {20x2 double}    [1x1 matlab.ui.style.Style]
3    row       { 1x2 double}    [1x1 matlab.ui.style.Style]
4    column    {[        7]}    [1x1 matlab.ui.style.Style]

The StyleConfigurations property value shows that style order numbers 1 and 4 affect columns, and that the row style was the third style added to the table. Remove the styles by specifying style order numbers 1, 3, and4.

Table UI component. The negative-valued data is displayed in bold red text. All cells have the default background color.

Input Arguments

collapse all

UI component, specified as one of these UI components:

A Table object created with theuitable function
A Tree object created with the uitree function
A ListBox object created with theuilistbox function
A DropDown object created with theuidropdown function

The component object must be parented to a figure created with theuifigure function or to one of its child containers.

Style order number, specified as a positive integer or a vector of positive integers. To determine the styles currently applied to the table, and the order in which they were added, query the value of the StyleConfigurations property.

When you remove a style other than the last one that was added, the remaining styles move up in the order to close the gaps. If no style order number is specified, all styles are removed from the UI component.

Example: removeStyle(comp,2) removes the second style in the list returned by comp.StyleConfigurations.

Example: removeStyle(comp,[1 3 5]) removes the first, third, and fifth styles in the list returned bycomp.StyleConfigurations.

Example: removeStyle(comp) removes all styles from the UI component.

Version History

Introduced in R2019b

To remove a style from a list box or drop-down UI component, specify theListBox or DropDown object as the first argument to the removeStyle function.

To remove a style from a tree, specify the Tree object as the first argument to the removeStyle function.
