GUI Popup

App: apps/gui_popup/

Demonstrates Nuklear’s popup and tooltip systems: a modal static popup (confirm dialog), a non-modal dynamic popup, and both simple and custom-content tooltips.

Run from root

% ./plume3d gui_popup

What it shows

• Static popup (modal) — opened by a button; contains OK/Cancel. Blocks interaction with the rest of the window until dismissed. type=0.
• Dynamic popup (non-modal) — floats above content without blocking. type=1.
• Simple tooltip (tooltip(text)) — shown on hover using isWidgetHovered().
• Custom tooltip (tooltipBegin / tooltipEnd) — allows arbitrary widget content inside the tooltip.

Key patterns

// Open a modal popup
if (Gui.buttonLabel("Show Confirm")) _showPopup = true

if (_showPopup) {
    // type=0 (static/modal), flags=268 (title+border+closable)
    if (Gui.popupBegin(0, "Confirm", 268, 150, 100, 250, 150)) {
        Gui.layoutRowDynamic(22, 1)
        Gui.label("Are you sure?")
        Gui.layoutRowDynamic(32, 2)
        if (Gui.buttonLabel("OK")) {
            _showPopup = false
            Gui.popupClose()
        }
        if (Gui.buttonLabel("Cancel")) {
            _showPopup = false
            Gui.popupClose()
        }
        Gui.popupEnd()
    } else {
        _showPopup = false  // closed via X button
    }
}

// Hover tooltip
Gui.buttonLabel("Hover me")
if (Gui.isWidgetHovered()) {
    Gui.tooltip("This is a tooltip!")
}
