flags

This instance variable may be a combination of zero or more of the following flags:

Constant	Description
`Pt_HIGHLIGHTED`	Draw a beveled border around the widget.
`Pt_AUTOHIGHLIGHT`	Automatically display/remove the highlight border as the cursor passes over the widget.

`Pt_TOGGLE`	The widget's SET flag will toggle on each mouse click instead of changing with mouse down/mouse up events.
`Pt_SELECTABLE`	The widget may be selected, causing `Pt_CB_ARM/ACTIVATE/DISARM` events.
`Pt_GHOST`	The widget is displayed 'ghosted'. This does not affect its response to events.
`Pt_BLOCKED`	The widget will be unresponsive to events.
`Pt_REALIZED`	The widget is visible on the display.
`Pt_CLIP_HIGHLIGHT`	The corners of the highlight rectangle are clipped off.
`Pt_OPAQUE`	Makes the widget opaque within its own extent and for everything behind it.
`Pt_DELAY_REALIZE`	The widget won't be realized except by a call to PtRealizeWidget().
`Pt_GETS_FOCUS`	The widget may get the keyboard focus.
`Pt_MENU_BUTTON`	Makes the widget a menu item.
`Pt_DESTROYED`	Marks the widget for destruction.
`Pt_DAMAGED`	Marks the widget for repairs.
`Pt_OBSCURED`	The widget is covered by another widget, or is outside its parent's canvas.

`Pt_CLEAR`	Keeps the widget's extent clear of any brothers in front of it.
`Pt_DAMAGE_FAMILY`	The widget and its children will be repaired.
`Pt_SELECT_NOREDRAW`	The widget will not redraw when it is selected.
`Pt_WIDGET_REBUILD`	The widget will be rebuilt once all resources have been changed.
`Pt_WIDGET_RESIZE`	The widget will be resized once all resources have been changed.
`Pt_PROCREATED`	The widget is a procreated child of a compound widget.
`Pt_ALL_BUTTONS`	The widget treats events on any mouse button as a selection.
`Pt_FOCUS_RENDER`	The widget will attempt to indicate that it has the keyboard focus through some means.
`Pt_CALLBACKS_ACTIVE`	Callbacks for this widget will be called due to changes through code, not just due to user interactions.
`Pt_MENUABLE`	This widget will respond to the menu button with a `Pt_CB_MENU` event.
`Pt_NOREDRAW_SET`	Noredraw Set
`Pt_FREE_MEMORY`	Frees memory associated with widget pointers.
