Can you show us the code you’re using here, and tell us what platform  
(Win/Linux/Mac) you’re using.

thanks

my code is

@label1 = StaticText.new(@picturebox2, -1, ‘Calculator’,  
Point.new(168,38), Size.new(213, 39))  
@label1.set\_foreground\_colour(Colour.new(255, 0, 255))  
@label1.set\_font(Font.new(15, FONTFAMILY\_DEFAULT, BOLD,  
FONTWEIGHT\_NORMAL, FALSE, ‘Kristen ITC’))

@picturebox2 is image background that I add to Panel  
I set like this and output it’s can work completely but background of  
‘Calculator’ label is gray and other label be the same :’(

On Windows at least, StaticText always draws its background in the theme  
background colour.

Instead of using StaticText, I would suggest drawing the text directly  
onto the bitmap using a DC (DeviceContext), inside an evt\_paint event.  
Use draw\_bitmap to paint the bitmap onto the frame, then draw\_text to  
draw the text atop it.

The simplest example of this can be found in the dialogs/dialogs.rb  
sample - search for on\_paint method.
