Hi all, I am trying to display a typical grey 'Delete Row', Icon on the uitoolbar. (Programmatically) But I cant find the proper value of 'CData' to be assigned.
Maybe somebody knows how to find the appropriate 'CData' and create the icon using uipushtool. I'm using this example from matlab help:
the help provided is too short :
h = figure('ToolBar','none')
ht = uitoolbar(h)
a = [.20:.05:0.95];
b(:,:,1) = repmat(a,16,1)';
b(:,:,2) = repmat(a,16,1);
b(:,:,3) = repmat(flipdim(a,2),16,1);
hpt = uipushtool(ht,'CData',b,'TooltipString','Hello')

CData is just a small image, you can use any image and you can resize images if necessary with imresize in the Image Processing Toolbox.
For example:
I = imread('peppers.png');
Icon = imresize(I,[16 16])
h = figure('ToolBar','none')
ht = uitoolbar(h)
hpt = uipushtool(ht,'CData',Icon,'TooltipString','Hello')
