MATLAB Central Newsreader - set background of uicontrol text box to be transparent?

set background of uicontrol text box to be transparent?

Vihang Patil — Sun, 11 May 2008 08:25:06 -0400

Hello
Is there any way to turn the background of the text box
uicontrol to be transparent?
ex: I have a figure window which has an image displayed on
it. I just want the text part of the uicontrol to be
displayed and want the rest of the part to be transparent
so that I can see the image displayed in the figure window
beneath it.

I have tried this but this doesnt help;

load trees
h1 = figure,
h2 = imshow(X,map);
h=uicontrol('style','text','string','hello');
set(h,'position',[100 150 50 20]);
parentColor = get(get(h, 'parent'), 'color');
set(h,'foregroundcolor', [0 0 0], ...
'backgroundcolor', parentColor);

The above will set the background of the text control to
that of the figure window and not the one of the trees.
Any help?
Vihang

Do you have to use uicontrol?
It doesn't accept BackgroundColor 'none', which is
the default of text objects.
h=text('string','hello','position',[140 150]);

Hello Pekka
Yes, I am very much interested to use uicontrol text box,
as it provide me flexibility to pick and place using guide.
The text() function, though solves my purpose but doesnt
give me that flexibilty to pick and place.
