GUILabel Color

[INIQUITOUS]

Hey,

I'm trying to change and update the TextColor of a GUILabel (instead of an image) but my code makes the label invisible altogether. Is there a setting i'm missing? This is my code.

class MyConfig extends GUICustomPropertyPage;

//various colour variables, mosliders etc...

function bool InternalDraw(Canvas Canvas)
{
	local color TestColor;
         
        //initially I only set currentColour.TextColor but i've since added the other code in a vain attempt to get the colour working.
        //I've also tried setting the style to STY_Normal.
	if(Canvas != None)
	{
		TestColor.R = currentColourR.GetValue();
		TestColor.G = currentColourG.GetValue();
		TestColor.B = currentColourB.GetValue();
		TestColor.A = 255;
		Canvas.Reset();
		Canvas.DrawColor = TestColor;
		currentColour.TextColor = TestColor;
	}

	return true;
}

defaultproperties
{
     Begin Object Class=GUILabel Name=MyColour
         StyleName="TextLabel"
         Caption="My Color:"
         WinWidth=0.181976
	 WinHeight=0.033333
	 WinLeft=0.334867
	 WinTop=0.255355
         RenderWeight=0.200000
         OnDraw=InternalDraw
     End Object
     currentColour=MyColour
}

Thanks for any help, ideas or suggestions!

I seemed to have solved it. It seems setting OnDraw to a component makes it invisible. I used a second invisible label to call the InternalDraw function and update the colours from there. :S

Keep in mind that On(Pre)Draw returns a boolean. The default implementation returns false to keep the built-in drawing stuff working. You return true, which means you want to handle all the drawing logic yourself.

Thank you Wormbo, very informative and it explains the behaviour of the components.

Here's a suggestion:

Change the TextColor variable of the Label when one of the Slider's value has changed.
Makes more sense than updating the color variable on every drawing call.

My way the value is constantly updated and you can see the colour change as the user moves the slider up and down (otherwise the colour would jump and not blend nicely).
