[Qgis-developer] quick noob python question

[Germán Carrillo]

Hi Duarte,

if I understood well, you would like to simulate a click in QGIS buttons.
For this you can use the slot trigger() of the available QAction's in the
class QgisInteface [1]. For example, if you want to open the "Open
Project..." dialog you can type this in the Python Console (inside QGIS):

 iface=qgis.utils.iface

iface.actionOpenProject().trigger()

Regarding Toolbars, you can also access them from the QgisInterface class.
For example, to access the Layer menu do this:

iface=qgis.utils.iface

m=iface.layerMenu()


Since a menu consists of a set of actions you could trigger any action of
the menu:


iface=qgis.utils.iface

m=iface.layerMenu()

for a in m.actions():

print a.text()

m.actions()[2].trigger()


Hope this helps.

Regards,

Germán
