getpixelposition

Get component position in pixels

Syntax

pos = getpixelposition(c)

pos = getpixelposition(c,isrecursive)

Description

pos = getpixelposition(c) returns the position in pixels of the component specified by c. MATLAB^® returns the position as a four-element vector that specifies the location and size of the component relative to its parent container in the form [left bottom width height].

pos = getpixelposition(c,isrecursive), where isrecursive is true, returns the component position relative to the parent figure. The default for isrecursive is false, which returns the position relative to its immediate parent container.

Examples

Get Position Relative to Panel

Create a push button within a panel container.

f = figure('Position',[300 300 300 200]);
p = uipanel('Position',[.2 .2 .6 .6]);
btn = uicontrol(p,'Style','PushButton', ...
     'Units','Normalized', ...
     'String','Push Button', ...
     'Position',[.1 .1 .5 .2]);

Get the position in pixels of the push button relative to its parent container, the panel.

pos = getpixelposition(btn)

pos =

   18.6000   12.6000   88.0000   23.2000

Get Position Relative to Figure Window

Create a push button within a panel container.

f = figure('Position',[300 300 300 200]);
p = uipanel('Position',[.2 .2 .6 .6]);
btn = uicontrol(p,'Style','PushButton', ...
     'Units','Normalized', ...
     'String','Push Button', ...
     'Position',[.1 .1 .5 .2]);

Get the position in pixels of the push button relative to its parent figure.

pos = getpixelposition(btn,true)

pos1 =
      80.6000   54.6000   88.0000   23.2000

Input Arguments

c — UI component

UI component object

UI component.

isrecursive — Return position relative to figure

false or 0 (default) | true or 1

Whether to return the position relative to the parent figure, specified as a numeric or logical 0 (false) or 1 (true).

• 0 (false) — The function returns the component position relative to its immediate parent.

• 1 (true) — The function returns the component position relative to the figure window.

More About

Pixels

On Windows^® and Macintosh systems, the size of a pixel is 1/96th of an inch. This size is independent of your system resolution.

On Linux^® systems, the size of a pixel is determined by your system resolution.
