Look & Feel - ComboBox Background.

[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,....

[DabDab]

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.

[David Healey]

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?

[Chazrox]

If you use a viewport and check 'useList'. Then you can make a transparent list area. You just have to also make a label of some sort showing the currently loaded index/value, so that the user can click to reveal the viewport list. Pretty much what a combobox is. Little hacky but I got what I wanted without doing anything too crazy. I prefer to do this when the list is very long, you can set it to open at a set size and have a nice scrollbar.

@David-Healey I just had a go at fixing this. Is that what you mean?

Content.makeFrontInterface(200, 200);

const laf = Content.createLocalLookAndFeel();

laf.registerFunction("drawPopupMenuBackground", function(g, obj)
{
    g.setColour("0x00000000"); // any transparent colour
    g.fillRect([0,0,200,200]);
});

laf.registerFunction("drawPopupMenuItem", function(g, obj)
{
    var a = obj.area;

    var padArea = [a[0] + 2, a[1] + 2, a[2] - 4, a[3] - 4];
    g.setColour(obj.isHighlighted ? Colours.green : Colours.blue);
    g.fillRoundedRectangle(padArea, 8);

    var textArea = [padArea[0] + 8, padArea[1], padArea[2] - 16, padArea[3]];
    g.setColour(Colours.white);
    g.setFont("Default", 14.0);
    g.drawAlignedText(obj.text, textArea, "left");
});

const ComboBox1 = Content.getComponent("ComboBox1");
ComboBox1.setLocalLookAndFeel(laf);

The drawPopupMenuBackground object should probably include an area, and the popup menu items still have a subtle drop shadow. But they're both fixes for another day.

Yes you'll need to wait for Christoph to merge it, use one of our forks, or make your own fork and pull in the PRs.

Great!
Can you point me to the Code you guys changed?
I want to stay with my Current Version of Hise for now

[David Healey]

@dannytaurus Do you think the same trick would work with alert windows?

[dannytaurus]

@David-Healey Yeah, can't see why not!

I've never used an AlertWindow. Do you have a small snippet?

Hmm.. what am I doing wrong? Loaded your snippet using the latest develop commit 3c36e36c.

@dannytaurus Ah you haven't got the rectangle class enabled I'm guessing, so a.reduced won't work. Just change it to a
