Look & Feel - ComboBox Background.

[Lindon]

@DanH gives me this;

and whilst thats a nice colour :-), its not what I'm looking for...

[DanH]

@Lindon can't you make it 0x00000000?

[Lindon]

@ulrik - oh yeah, very odd I think...

[Lindon]

@DanH said in Look & Feel - ComboBox Background.:

@Lindon can't you make it 0x00000000?

hmm, just randomly throwing hex values into the ring isnt helping here...try it yourself and see if this works (hint: it doesnt)

[DanH]

@Lindon so sorry

[Lindon]

this gets a strange result:

ComboBoxLAF.registerFunction("drawPopupMenuBackground", function(g, obj)
{
	//var a = obj.area;
	g.setColour(Colours.red);
    g.drawRect([0,0,2000,2000], 1);
});

you get this:

-- see the little red line on the left side?

ComboBoxLAF.registerFunction("drawPopupMenuBackground", function(g, obj)
{
	//var a = obj.area;
	g.setColour(Colours.red);
    g.fillRect([0,0,2000,2000]);
});

predictably gets this:

but this:

ComboBoxLAF.registerFunction("drawPopupMenuBackground", function(g, obj)
{
	//var a = obj.area;
	g.setColour(0x00000000);
    g.fillRect([0,0,2000,2000]);
});

gets us back to this:

@Lindon I'm pretty sure you can't make the background of the combo box transparent. It will give a white outline (the panel is opaque basically). You can make the individual items have a transparent background though.

[Lindon]

@d-healey - yeah that's the position I'm rapidly reaching. Thanks. I'm not sure this is a bug but its certainly a feature it would be nice to have,....

BG CB transparent is not a bug. Transparent is not possible right now with out altering the source Code. How ever it will be a good feature request to have CB transparent BG.

I would like to give this one a bump. According to everything I read on the JUCE forum, the popup menu is by default opaque, unless you set PopupMenu::backgroundColourId to a colour with an alpha < 1.0.

I've been through all the HISE popup look and feel functions I could find and set this property to transparentWhite but still the combo boxes show a white background.

@Christoph-Hart Any ideas?
