Uses python to generate a temporary button on the toolbar.
from PyQt4.QtCore import QObject, SIGNAL from PyQt4.QtGui import QAction, QIcon
action = QAction(QIcon(“”””), ““Turn labels”” + ““\n”” + ““ON/OFF””, iface.mainWindow()) action.setCheckable(True) iface.addToolBarIcon(action)
def label_control(): for layer in QgsMapLayerRegistry.instance().mapLayers().values(): if action.isChecked() == True: layer.setCustomProperty(““labeling/enabled””, True) else: layer.setCustomProperty(““labeling/enabled””, False) layer.triggerRepaint()
QObject.connect(action, SIGNAL(““triggered()””), label_control)
