Description:

The PtTab class draws a tab such as is found on a file folder. Clicking the tab invokes an application callback.

A group of PtTab widgets positioned at the top of a PtPane.

When using PtTab, you might want to:

• Group the tabs together and set the Pt_GROUP_EXCLUSIVE bit in the PtGroup widget's Pt_ARG_GROUP_FLAGS resource. This flag allows only one of the tabs to be set at a time.
• Use other PtGroup flags and resources to make the tabs the same size, aligned horizontally, and so on. For more information, see "Aligning widgets using groups" in the Geometry Management chapter of the Photon Programmer's Guide.
• Place the tabs at the top of a PtPane or some other container. Use the same border width for the tabs and the container, and line up the top of the container's border with the top of the bevel on the tab.
• Use PhAB's Picture module and internal links to change the contents of the container widget for the tabs. For more information, see the Photon Programmer's Guide.

New resources:

Pt_ARG_TAB_FLAGS

Flags that affect how the widget appears. The only bit defined is:

Pt_TAB_UPSIDE_DOWN

Display the rounded corners on the bottom of the widget instead of the top.

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.
