Creates a new QextMdiChildFrm class.

Delicato : destroys this QextMdiChildFrm If a child is still here managed (no recreation was made) it is destroyed too.

Reparents the widget w to this QextMdiChildFrm (if this is not already done) Installs an event filter to catch focus events. Resizes this mdi child in a way that the child fits perfectly in.

Reparents the client widget to 0 (desktop), moves with an offset from the original position Removes the event filter.

Sets the window icon pointer.

Returns the child frame icon.

Enables or disables the close button

Sets the caption of this window

Returns the caption of this mdi child. Cool to have it inline...

Minimizes , Maximizes or restores the window.

Returns the current state of the window Cool to have it inline...

[const]

Returns the inner client area of the parent of this (which is QextMdiChildArea).

[const]

Returns the geometry that will be restored by calling restore().

Sets the geometry that will be restored by calling restore().

Forces updating the rects of the caption and so... It may be useful when setting the mdiCaptionFont of the MdiManager

Returns the system menu.

Returns the caption bar height

sets new raise behaviour and pixmaps of the buttons depending on the current decoration style

[const]

returns the mouse state "In Drag"

[const]

returns the mouse state "In Resize"

Internally called from the signal focusInEventOccurs. It raises the MDI childframe to the top of all other MDI child frames and sets the focus on it.

[virtual]

Sets the minimum size of the widget to w by h pixels. It extends it's base clase method in a way that the minimum size of the child area will be set additionally if the view is maximized.

[slot]

[protected virtual]

Reimplemented from its base class. Resizes the captionbar, relayouts the position of the system buttons, and calls resize for its embedded client QextMdiChildView with the proper size

[protected virtual]

Reimplemented from its base class. Detects if the mouse is on the edge of window and what resize cursor must be set. Calls QextMdiChildFrm::resizeWindow if it is in m_bResizing.

[protected virtual]

Reimplemented from its base class. Colours the caption, raises the childfrm widget and turns to resize mode if it is on the edge (resize-sensitive area)

[protected virtual]

Reimplemented from its base class. Sets a normal cursor and leaves the resize mode.

[protected virtual]

Reimplemented from its base class. give its child view the chance to notify a childframe move... that's why it sends a QextMdiChildMovedEvent to the embedded QextMdiChildView .

[protected virtual]

Reimplemented from its base class. If not in resize mode, it sets the mouse cursor to normal appearance.

[protected virtual]

Reimplemented from its base class. Additionally it catches

• the client's mousebutton press events and raises and activates the childframe then
• the client's resize event and resizes its childframe widget (this) as well

[protected]

Calculates the new geometry from the new mouse position given as parameters and calls QextMdiChildFrm::setGeometry

[protected]

Override the cursor appearance depending on the widget corner given as parameter

[protected]

changes from the resize cursor to the normal (previous) cursor

[protected virtual]

That means to show a mini window showing the childframe's caption bar, only. It cannot be resized.

[protected slots slot]

Handles a click on the Maximize button

[protected slots slot]

Handles a click on the Restore (Normalize) button

[protected slots slot]

Handles a click on the Minimize button.

[protected slots slot]

Handles a click on the Close button.

[protected slots slot]

Handles a click on the Undock (Detach) button

[protected slots slot]

Shows a system menu for child frame windows.

[protected]

Restore the focus policies for _all_ widgets in the view using the list given as parameter. Install the event filter for all direct child widgets of this. (See QextMdiChildFrm::eventFilter )

[protected]

Backups all focus policies of _all_ child widgets in the MDI childview since they get lost during a reparent. Remove all event filters for all direct child widgets of this. (See QextMdiChildFrm::eventFilter )

[protected]

Calculates the corner id for the resize cursor. The return value can be tested for: QEXTMDI_RESIZE_LEFT, QEXTMDI_RESIZE_RIGHT, QEXTMDI_RESIZE_TOP, QEXTMDI_RESIZE_BOTTOM or an OR'd variant of them for the corners.
