class QgsApplicationExitBlockerInterface
|
|
{
|
|
%Docstring(signature="appended")
|
|
An interface that may be implemented to allow plugins or scripts to temporarily block
|
|
the QGIS application from exiting.
|
|
|
|
This interface allows plugins to implement custom logic to determine whether it is safe
|
|
for the application to exit, e.g. by checking whether the plugin or script has any
|
|
unsaved changes which should be saved or discarded before allowing QGIS to exit.
|
|
|
|
:py:class:`QgsApplicationExitBlockerInterface` are registered via the iface object:
|
|
|
|
Example
|
|
-------------------------------------
|
|
|
|
.. code-block:: python
|
|
|
|
class MyPluginExitBlocker(QgsApplicationExitBlockerInterface):
|
|
|
|
def allowExit(self):
|
|
if self.has_unsaved_changes():
|
|
# show a warning prompt
|
|
# ...
|
|
# prevent QGIS application from exiting
|
|
return False
|
|
|
|
# allow QGIS application to exit
|
|
return True
|
|
|
|
my_blocker = MyPluginExitBlocker()
|
|
iface.registerApplicationExitBlocker(my_blocker)
|
|
|
|
.. versionadded:: 3.16
|
|
%End
|
|
|
|
%TypeHeaderCode
|
|
#include "qgsapplicationexitblockerinterface.h"
|
|
%End
|
|
public:
|
|
virtual ~QgsApplicationExitBlockerInterface();
|
|
|
|
virtual bool allowExit() = 0;
|
|
%Docstring
|
|
Called whenever the QGIS application has been asked to exit by a user.
|
|
|
|
The subclass can use this method to implement custom logic handling whether it is safe
|
|
for the application to exit, e.g. by checking whether the plugin or script has any unsaved
|
|
changes which should be saved or discarded before allowing QGIS to exit.
|
|
|
|
The implementation should return ``True`` if it is safe for QGIS to exit, or ``False`` if it
|
|
wishes to prevent the application from exiting.
|
|
|
|
.. note::
|
|
|
|
It is safe to use GUI widgets in implementations of this function, including message
|
|
boxes or custom dialogs with event loops.
