I added a Background Image but now I can't see panels...

Hi everybody!

I set a background for my figure, but now, when I add a panel, I only see the title, the rest of the panel is transparent, and I see my background... There's something I can do?? I tried using "Bring to front" and "Send to back", no results!

That is the behavior you would get if the BackgroundColor property of the uipanel is 'none' . Perhaps you set the color explicitly in your uipanel() call? Or perhaps you have set the root property DefaultUipanelBackgroundColor that is set to 'none' ?

get(0,'DefaultUipanelBackgroundColor')

[Jethro]

No results. I set the color manually. All parameters are not set on "null", but my panel is still transparent.

I can only see the title and the radio buttons I used...

[Walter Roberson]

Which OS are you using, and which MATLAB release?

Also, what does

get(gcf, 'Renderer')

report?

[Jethro]

Windows 7, Matlab 7.12.0 (R2011a), and the get returns me "painters"

[Walter Roberson]

What happens if you try

set(gcf,'Renderer', 'OpenGL')

Answer 2

H = uipanel(..)

What does:

get(H,'backgroundcolor')

return?

[Jethro]

ans=

0.8000 0.8000 0.8000

It's the color I set, but I can't see the panel... I only see radio buttons...

[Sean de Wolski]

Unable to replicate:

hF = figure;

axes;

uipanel('pos',[.3 .3 .3 .3],'backgroundcolor',[0.8 0.8 0.8]);

[Jethro]

Nothing to do... Even if I set it like this it it transparent

[Sean de Wolski]

I am not able to replicate this. If you run my three line of code above, the uipanel is on top of the blank white axes in a new figure?

[Sean de Wolski]

Perhaps it's your choice of liquor. I think the renderers prefer gin.

Answer 3

[Jethro]

Nothing to do...

I can't understand why when I don't see my background, everything it's ok, but when I use it, panels became transparent...

This is it:

With the BG

Without the BG

What's the problem???!

[Walter Roberson]

A Windows Aero problem, perhaps? You might have to turn on the Classic layout (or whatever it is called.)

[Jethro]

Nope.. It's the same...

There's a way to bring to front my panel using code?

[Walter Roberson]

What happens if you try

opengl hardware

set(gcf,'Renderer', 'OpenGL')

drawnow

and look at the output, and if that did not work,

opengl software

set(gcf,'Renderer', 'OpenGL')

drawnow

Your panel probably _is_ at the front from what you have described. (Your test works as expected for Sean and I.)
