Detailed Description

The main frame widget QextMdiMainFrm consists of 2 child widgets. One is this class. It's the widget where the child frames (emulated toplevel MDI views) live in. This class is the manager for the child frame widgets because it controls the Z-order widget stack of QextMdiChildFrm's. It provides all placing and positioning algorithms for docked (attached) MDI views.

QextMdiChildArea doesn't know anything about the actual MDI views. It only knows and manages the frame widgets of attached MDI views. All actions and stuff concerning only to childframes are handled here.

Consruction. Note: This class needn't to know about QextMdiMainFrm .

Destructor : THERE should be no child windows anymore... Howewer it simply deletes all the child widgets :)

Appends a new QextMdiChildFrm to this manager. The child is shown,raised and gets focus if this window has it.

Destroys a QextMdiChildFrm managed.
Note that if a client is attached to this child , it is deleted too!

Destroys a QextMdiChildFrm managed.
Note that if a client is attached to this child , it is NOT deleted!

Brings the child lpC to the top of the stack The children is focused if bSetFocus is TRUE otherwise is raised only

Returns the topmost child (the active one) or 0 if there are no children. Note that the topmost child may be also hidded , if ALL the windows are minimized.

Returns the number of visible children

Calculates the cascade point for the given index. If index is -1 the cascade point is calculated for the window following the last window

Sets the MDI childframe window caption font (no relayout)

Sets the foreground color of the active MDI childframe window caption (no relayout)

Sets the background color of the active MDI childframe window captions (no relayout)

Sets the foreground color of inactive MDI childframe window captions (no relayout)

Sets the background color of inactive MDI childframe window captions (no relayout)

Positioning of minimized child frames

[protected]

Internally used for the tile algorithm

[protected virtual]

Automatically resizes a maximized MDI view and layouts the positions of minimized MDI views.

[protected]

Shows the 'Window' popup menu on right mouse button click

[protected]

Internally used. Actions that are necessary when an MDI view gets minimized

[signal]

Signalizes that there aren't maximized child frames any more

[signal]

Signalizes that the child frames are maximized now

[signal]

Internally used. Signalizes from QextMdiChildArea to QextMdiMainFrm that the signal/slot connections of the system buttons in the menubar (only in Maximize mode) must be updated to another MDI view because the focused MDI view has changed

[signal]

Internally used. Signalizes from QextMdiChildArea to QextMdiMainFrm that the 'Window' popup menu must be shown

[signal]

Signalizes that the last attached (docked) MDI view has been closed. Note: Detached MDI views can remain.
