PtDisjoint

Superclass for disjoint widgets

Class hierarchy:

PtWidget --> PtBasic --> PtContainer --> PtDisjoint

Immediate subclasses:

• PtMenu
• PtRegion
• PtWindow

For more information, see the diagram of the widget hierarchy.

PhAB icon:

None -- not normally instantiated.

Public header:

<photon/PtDisjoint.h>

Description:

PtDisjoint is the superclass for the widget classes that are disjoint (i.e. are instantiated without a parent).

New resources:

Resource	C type	Pt type	Default
Pt_ARG_SYSINFO	PhSysInfo_t *	Struct	See below.
Pt_CB_SYSINFO	PtCallback_t *	Link	NULL

Pt_ARG_SYSINFO (read only)

C type	Pt type	Default
PhSysInfo_t *	Struct	See below.

If you get the value of this resource, you get a pointer to a PhSysInfo_t structure (see the Photon Library Reference) that indicates the conditions above this widget.

Pt_CB_SYSINFO

C type	Pt type	Default
PtCallback_t *	Link	NULL

A list of PtCallback_t structures that define the callbacks invoked when the widget receives a Ph_EV_INFO event.

Each callback is passed a PtCallbackInfo_t structure that contains at least the following members:

reason

Pt_CB_SYSINFO

reason_subtype

One of:

• Ph_FEP -- the information is from a "front-end input processor." You can get the data with this code:

  PhFEPInfo_t *fep_info = PhGetData( event );
      

• Ph_INVALIDATE_SYSINFO -- the rendering environment has changed. No data is included in the event; if you need it, call PhQuerySystemInfo() or PtQuerySystemInfo(), both of which are described in the Photon Library Reference.

event

A pointer to a PhEvent_t structure that describes the event that caused the callback to be invoked.

cbdata

NULL.

These callbacks should return Pt_CONTINUE.

Inherited resources:

If the widget modifies an inherited resource, the "Default override" column indicates the new value. This modification affects any subclasses of the widget.
