GUI Combo

App: apps/gui_combo/

Demonstrates all three comboBegin* variants: a text-item dropdown, a color-swatch dropdown with an embedded colorPicker, and a symbol (icon) dropdown.

Run from root

% ./plume3d gui_combo

What it shows

• Label combo — standard item list; comboItemLabel returns true on selection.
• Color combo — opens with a color swatch; embeds a colorPicker inside the dropdown. Colors are 0–255.
• Symbol combo — opens with a Nuklear symbol icon; items are comboItemSymbolLabel.

Key patterns

// Label combo
if (Gui.comboBeginLabel(_items[_selected], 200, 200)) {
    Gui.layoutRowDynamic(25, 1)
    for (i in 0..._items.count) {
        if (Gui.comboItemLabel(_items[i], 17)) _selected = i
    }
    Gui.comboEnd()
}

// Color combo with inline picker (colors 0-255)
if (Gui.comboBeginColor(_r, _g, _b, _a, 200, 300)) {
    Gui.layoutRowDynamic(120, 1)
    var result = Gui.colorPicker(_r, _g, _b, _a, 1)  // returns [r,g,b,a] 0-255
    _r = result[0]
    _g = result[1]
    _b = result[2]
    Gui.comboEnd()
}
