Showing only one image in a TSpeedButton
Hi
When I load a glyph into a TSpeedButton at runtime, and it contains more than one image, it wants to display them all at the same time. How do I get the button to display only the first image?

adjust the numglyphs property to the count of images of your bitmap
set NumGlyphs to 4, I guess
Perhaps with this code?
These lines of code load a four-image bitmap into the Glyph property of a speed button, and specify the appropriate value for the NumGlyphs property:
SpeedButton1.Glyph.LoadFro
SpeedButton1.NumGlyphs := 4;
These lines of code load a four-image bitmap into the Glyph property of a speed button, and specify the appropriate value for the NumGlyphs property:
SpeedButton1.Glyph.LoadFro
SpeedButton1.NumGlyphs := 4;

Thanks for the replies.
I have tried using the NumGlyphs property, but I still find that the speedbutton tries to load all the images at once. This is my code:
GlyphBtn[UpTo].NumGlyphs := 1;
GlyphBtn[UpTo].Glyph.LoadF
(I am using FindFirst etc to locate the bitmaps). I also tried setting NumGlyphs after loading the image, but I still get the same result. Any ideas?

>adjust the numglyphs property to the count of images of your bitmap
contains your bitmap 4 pictures then set NumGlyphs to 4 -> one image is shown on the speedbutton
contains your bitmap 2 pictures then set NumGlyphs to 2 -> one image is shown on the speedbutton

Thanks Meikl
How do I know how many images there are in the bitmap?

Hello Fraction
I never realised it would be so complicated! You gave me the right idea. I divided the width by 24 (an average size) and used the integer result as the answer. It seem to work OK. I am surprised there is not a property called ImageCount or something.
