GUI Toggles

App: apps/gui_toggles/

Demonstrates the three selection-state widgets: checkbox for independent toggles, radio for exclusive group selection, and selectableLabel for list selection.

Run from root

% ./plume3d gui_toggles

What it shows

• Checkboxes — four independent toggles (shadows, vsync, fullscreen, debug). Each is stored in its own Bool variable and updated each frame.
• Radio buttons — quality level (Low/Medium/High/Ultra). Implemented as four radio calls sharing an integer index; only one can be active at a time.
• Selectable labels — an item list (_items) where clicking sets _selectedItem. Shows both align and selected parameters.

Key patterns

// Independent checkbox
_shadows = Gui.checkbox("Enable Shadows", _shadows)
_vsync   = Gui.checkbox("VSync", _vsync)

// Exclusive radio group (compare against index)
if (Gui.radio("Low",    _quality == 0)) _quality = 0
if (Gui.radio("Medium", _quality == 1)) _quality = 1
if (Gui.radio("High",   _quality == 2)) _quality = 2
if (Gui.radio("Ultra",  _quality == 3)) _quality = 3

// Selectable label list (align=17 = NK_TEXT_LEFT)
for (i in 0..._items.count) {
    if (Gui.selectableLabel(_items[i], 17, _selectedItem == i)) {
        _selectedItem = i
    }
}
Gui.label("Selected: %(_selectedItem >= 0 ? _items[_selectedItem] : "none")")
