gboolean x_event_configure ( GtkWidget *  widget,
GdkEventConfigure *  event,
gpointer  user_data 
)
Function Description
This is the callback function connected to the configure event of the drawing area of the main window.

It updates the size of the backingstore for the associated toplevel structure (creates a new pixmap) and re-pans each of its pages to keep their contents centered in the drawing area.

When the window is maximised, the zoom of every page is changed to best fit the previously displayed area of the page in the new area. Otherwise the current zoom level is left unchanged.

Parameters:
[in]widgetThe drawing area which received the signal.
[in]eventThe event structure of signal configure-event.
[in]user_dataThe toplevel environment as user data.
Returns:
FALSE to propagate the event further.

Function Description
This function gets the pointer position of the drawing area of the current workspace GSCHEM_TOPLEVEL. The flag snapped specifies whether the pointer position should be snapped to the current grid.
Parameters:
[in]w_currentThe GSCHEM_TOPLEVEL object.
[in]snappedAn option flag to specify the wished coords
[out]wxsnapped/unsnapped world x coordinate
[out]wysnapped/unsnapped world y coordinate
Returns:
Returns TRUE if the pointer position is inside the drawing area.
