Member Function Documentation

void KivioCanvas::startSpawnerDragDraw ( const QPoint &  p  ) 

Starts a new drag & draw (called from the drag enter event).

Parameters:
p The point to begin at
This will allocate a new KivioStencil for drawing with and set some class variables used during redraws.

Definition at line 547 of file kivio_canvas.cpp.

void KivioCanvas::continueSpawnerDragDraw ( const QPoint &  p  ) 

Undraws the old stencil outline, draws the new one.

Definition at line 596 of file kivio_canvas.cpp.

void KivioCanvas::endSpawnerDragDraw (  ) 

Ends the ability to draw a drag & drop spawner object.

Definition at line 663 of file kivio_canvas.cpp.

void KivioCanvas::beginUnclippedSpawnerPainter (  ) 

Creates a new spawner drawing object.

Definition at line 695 of file kivio_canvas.cpp.

void KivioCanvas::endUnclippedSpawnerPainter (  ) 

Deletes the current spawner drawing object.

Definition at line 726 of file kivio_canvas.cpp.

void KivioCanvas::dragEnterEvent ( QDragEnterEvent *  e  )  [protected, virtual]

Handles the initial drag event.

Parameters:
e The event
This will check to make sure the drag object is of the correct mimetype. If it is, it accepts it, and the calls startSpawnerDragDraw which will allocate a new drawing object and set some class variables for future drawing.

Definition at line 822 of file kivio_canvas.cpp.

void KivioCanvas::dragMoveEvent ( QDragMoveEvent *  e  )  [protected, virtual]

Handles drag-move events.

Parameters:
e The event
This makes sure the drag object is of type kivio/stencilSpawner since these are currently the only type of mime-types accepted. If so, it accepts the event, and then tells the drawing object to update itself with a new position.

Definition at line 844 of file kivio_canvas.cpp.

void KivioCanvas::dragLeaveEvent ( QDragLeaveEvent *   )  [protected, virtual]

Handles when a drag leaves this object.

Parameters:
e The event object
This will call endSpawnerDragDraw() which terminates the drawing object and ends interaction with the drag.

Definition at line 892 of file kivio_canvas.cpp.

void KivioCanvas::dropEvent ( QDropEvent *  e  )  [protected, virtual]

Handles drops for this object.

Parameters:
e The drop event object
This function takes care of handling the final drop event of this object. It will allocate a new object of the currently dragged Spawner type (stencil), and add it to the active page of the document (which actually adds it to the active layer of the active page).
