tab_stack ->append: tab

Append a tab object to the right of the member tabs. If it is the first tab, it will become the one tab_stack->on_top. Tabs may be added both before and after displaying a tab_stack. See tab_stack->layout_dialog for fixing the layout after adding to a displayed tab_stack.

tab_stack ->erase: graphical

Erases a tab object or graphical from the tab-stack. Ensures another tab is raised if this is the tab_stack<-on_top tab and recompute the layout of the tabs. See also device->erase.

tab_stack ->initialise: member=tab ...

Create a tab-stack holding the argument members. The arguments are handed to tab_stack->append, left to right.

tab_stack ->layout_dialog: [size]

This method is normally called by the generic dialog layout mechanism to fix the layout of its members. It will invoke dialog_group->layout_dialog to force all member tab objects to adjust themselves to the requested size.

If size is @default, the system will invoke dialog_group->layout_dialog to all its members and then compute the union of the member tab objects to determine the required size. Next it will call this method again with the computed size.

tab_stack ->on_top: member:tab

Put indicated tab on top of the others. Normally this is called from the tab->event method after the user clicks on the label. of a hidden tab object.

Note that the argument may be the name of the tab rather than the tab itself.
