Border Constraints Properties

Description of the border constraints set of properties.

Syntax

constraints = createConstraints("border")
constraints = createConstraints("border", position)
constraints = createConstraints("border", position, preferredsize)

Arguments

position

A string

"top" | "left" | {"center"} | "right" |"bottom"

The position of the element in the layout

preferredsize

[width, height] a 1-by-2 matrix of doubles, [-1, -1] by default.

The preferred width or height of the element in the layout in pixels if not constrained.

constraints

The created constraints.

Description

This functions creates the border constraints to set the constraints attribute of an uicontrol.

Examples

//Creating a figure with the border layout with 50 pixel padding in width and 10 in height
f = figure( ...
"dockable"        , "off",...
"infobar_visible" , "off",...
"toolbar"         , "none",...
"menubar_visible" , "off",...
"menubar"         , "none",...
"default_axes"    , "off",...
"layout"          , "border",...
"layout_options", createLayoutOptions("border", [50,10]),...
"visible"         , "on");

c = createConstraints("border", "top", [50,10]);
//First frame is on top with 10 pixel in height
u_grid1 = uicontrol(f,...
"style", "frame",...
"backgroundcolor", [1 0 0], ...
"constraints", c);

sleep(500);
c.position = "left";
u_grid2 = uicontrol(f,...
"style", "frame",...
"backgroundcolor", [0 1 0], ...
"constraints", c);

sleep(500);
c.position = "center";
u_grid3 = uicontrol(f,...
"style", "frame",...
"backgroundcolor", [0 0 1], ...
"constraints", c);

sleep(500);
c.preferredsize = [10, 100];
c.position = "right";
u_grid4 = uicontrol(f,...
"style", "frame",...
"backgroundcolor", [1 1 0], ...
"constraints", c);

sleep(500);
c.position = "bottom";
u_grid5 = uicontrol(f,...
"style", "frame",...
"backgroundcolor", [1 0 1], ...
"constraints", c);
