General Containers

• GUI.Panel()
• GUI.ScrollPane([view])
• GUI.SplitPane([orientation]) (Horizontal by default)

Controls & Inputs

• Buttons: GUI.Button(text), GUI.ToggleButton(text)
• Selections: GUI.CheckBox(text), GUI.RadioButton(text)
• Text Data: GUI.Label(text), GUI.TextField([text]), GUI.TextArea([text])
• Pickers: GUI.ComboBox(), GUI.List(), GUI.Slider([min, max, value]), GUI.ProgressBar([min, max])
• Complex: GUI.Tree() (Uses GUI.TreeNode), GUI.ColorChooser(), GUI.FileChooser()

Menus

• GUI.MenuBar()
• GUI.Menu(text): Add to MenuBar, responds to onSelect(...)
• GUI.MenuItem(text): Responds to onAction(...)

Event Handling

Event Registration	Callback Signature
comp.onClick("funcName")	funcName()
comp.onMouse("funcName")	funcName(type, x, y, button, clickCount)
comp.onKey("funcName")	funcName(type, keyCode, keyChar, modifiers)
menu.onSelect("funcName")	funcName(action)

Example

win = GUI.Window("My App");
panel = GUI.Panel();
btn = GUI.Button("Click Me");

function onClick(type, x, y, btn, c) {
    print("Clicked!");
}
btn.onMouse("onClick");

panel.add(btn);
win.add(panel);
win.setSize(300, 200);
win.show();
