GUI Opacity

[LordNyson]

Wondering how to fix this problem. Basically I have drop down boxes, combo boxes. But when you drop down the one on top you can still see the others through it, I need a way to make it opaque. I have looked at trying to do it with gi->getSkin()->setColor() But I just can't seem to get it working. Can anyone help?

Maybe it's because you setted a transparency? Could you post a sample code to let us test it?

This is because GUI elements as default are transparent. Try adjusting their transparency to 255 and see that theyre much brighter and theres no bug that you posted

Yeah I know it's not a bug, I just don't know how to do it! How do I adjust the transparency to 255? Is it part of the GUI object or part of each combo box? They are just default creation of a combo box, I just can't work out how to adjust the transparency of the combo-box background

Code: Select all

s32 alpha = 255;

for (u32 i = 0; i < EGDC_COUNT ; ++i)
{
	SColor color = env->getSkin()->getColor ((EGUI_DEFAULT_COLOR)i);
	color.setAlpha (alpha);
	env->getSkin()->setColor ((EGUI_DEFAULT_COLOR)i, color);
}

Thanks man, so basically that just sets every GUI elements Alpha to 255... it looks very... Windows 95ish, I will have to play around to get the right ones... but thanks for the code, in essence it does what I need.

More specifically for future reference:

SColor color = gi->getSkin()->getColor (EGDC_3D_HIGH_LIGHT);
color.setAlpha (225);
gi->getSkin()->setColor (EGDC_3D_HIGH_LIGHT, color);

Where EGDC_3D_HIGH_LIGHT = 3;

I think there are no functions to set a transparency to only one GUI Element.
