S40 FullTouch: Icons (List, Categorybar) not displayed on device

Hello developers,

I have icons displayed in the emulator, but not on the device.

Normally this is because of some lower/uppercase problems( which windows ignores) .

But my icons are displayed when I paint them on a canvas. So there is noting wrong with the image pathes, and the device is able to display them.

When I display them in an LCDUI-List or in a Full-Touch-Category-Bar, they are not displayed.

Are there constraints for the icons? My icons are 24pixels square, png, 8bit-color or 4-bit color, without transparency.

Not aware of anything, but category bar icons should be white, shouldn’t they? Anyway, I would start with the [url=http://projects.developer.nokia.com/s40uivisualisation/wiki]Series 40 UI Component Demos[/url] and replace their icons with my ones.

@Karsten, If I remember the icon size for category bar is 26x26 - Can you give a try with sample icons available in Nokia Icon ToolKit ? [url]http://www.developer.nokia.com/Resources/Library/Full_Touch/#!icon-creation.html[/url]

It looks like the png is not allowed to be indexed.
24 Pixel width is not a problem.
When I store them as grayscale, it is displayed in the category bar.

I also got success to have a rbg colors png as list icon, with bright red. But a indexed file with only two gray colors in the color map is not displayed.
(on older phones it was the the other way around, 24bit rgb was problematic. Also I normally try to compress images as much as possible in mobile development)
