Shortcut to change output layer

[Segmentoholic]

Hello,

is it possible to set a shortcut to change output layer file of Geo-SAM faster?

Thank you for your help in advance!

This feature might not be essential. You can modify the code as needed. Binding a shortcut key is straightforward. Define it in tools/widgetTool.py:

Geo-SAM/tools/widgetTool.py

Lines 236 to 260 in c2c8b86

	self.shortcut_clear = QShortcut(QKeySequence(Qt.Key_C), self.wdg_sel)
	self.shortcut_undo = QShortcut(QKeySequence(Qt.Key_Z), self.wdg_sel)
	self.shortcut_save = QShortcut(QKeySequence(Qt.Key_S), self.wdg_sel)
	self.shortcut_hover_mode = QShortcut(QKeySequence(Qt.Key_P), self.wdg_sel)
	self.shortcut_tab = QShortcut(QKeySequence(Qt.Key_Tab), self.wdg_sel)
	self.shortcut_undo_sam_pg = QShortcut(
	QKeySequence(QKeySequence.Undo), self.wdg_sel
	)
	# connect shortcuts
	self.shortcut_clear.activated.connect(self.clear_layers)
	self.shortcut_undo.activated.connect(self.undo_last_prompt)
	self.shortcut_save.activated.connect(self.save_shp_file)
	self.shortcut_hover_mode.activated.connect(self.toggle_hover_mode)
	self.shortcut_tab.activated.connect(self.loop_prompt_type)
	self.shortcut_undo_sam_pg.activated.connect(self.undo_sam_polygon)
	# set context for shortcuts to application
	# this will make shortcuts work even if the widget is not focused
	self.shortcut_clear.setContext(Qt.ApplicationShortcut)
	self.shortcut_undo.setContext(Qt.ApplicationShortcut)
	self.shortcut_save.setContext(Qt.ApplicationShortcut)
	self.shortcut_hover_mode.setContext(Qt.ApplicationShortcut)
	self.shortcut_tab.setContext(Qt.ApplicationShortcut)
	self.shortcut_undo_sam_pg.setContext(Qt.ApplicationShortcut)

And then unbind it in the unload function:

Geo-SAM/tools/widgetTool.py

Lines 382 to 399 in c2c8b86

	def unload(self):
	"""Unload actions when plugin is closed"""
	self.clear_layers(clear_extent=True)
	if hasattr(self, "shortcut_tab"):
	self.disconnect_safely(self.shortcut_tab)
	if hasattr(self, "shortcut_undo_sam_pg"):
	self.disconnect_safely(self.shortcut_undo_sam_pg)
	if hasattr(self, "shortcut_clear"):
	self.disconnect_safely(self.shortcut_clear)
	if hasattr(self, "shortcut_undo"):
	self.disconnect_safely(self.shortcut_undo)
	if hasattr(self, "shortcut_save"):
	self.disconnect_safely(self.shortcut_save)
	if hasattr(self, "shortcut_hover_mode"):
	self.disconnect_safely(self.shortcut_hover_mode)
	if hasattr(self, "wdg_sel"):
	self.disconnect_safely(self.wdg_sel.MapLayerComboBox.layerChanged)
	self.iface.removeDockWidget(self.wdg_sel)

To find the shortcut key binding, use QT Designer to open ui/Selector.ui. Click the button you want to bind, check its objectName

and find the corresponding connect function in tools/widgetTool.py (self.set_vector_layer in this case).

Geo-SAM/tools/widgetTool.py

Line 178 in c2c8b86

self.wdg_sel.MapLayerComboBox.layerChanged.connect(self.set_vector_layer)

To enable modification, you need to reload the plugin. You can install the Plugin Reloader plugin to reload the plugin without restarting QGIS.
