[Qgis-developer] quick noob python question

[Duarte Carreira]

Hi Germán.

Your tips are exactly what I was looking for!

So I can now open a dialog:

iface=qgis.utils.iface
menu=iface.layerMenu()
myActions=menu.actions()
myAction=[ac for ac in myActions if ac.objectName()=="mActionEmbedLayers"][0]
myAction.trigger()

So now for the final 1 million dollar question: can I change the first textbox in the dialog?

Thanks,
Duarte

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

for a in m.actions():

print a.text()

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

Hope this helps.

Regards,

Germán

Just an additional question: generally speaking the gui is not accessible from python? We cannot simulate a toolbar button click, or menu item?

Germán, thanks.

Maybe that's what I'll do, but it pains me to duplicate code...

Hi Duarte,

from my experience it is not possible. You can of course re-use the ui file and implement the whole functionality on your own based on the cpp file, basically a translation from C++ to Python. I've done this before and it is not a complex process, but it requires time.

By the way, the folder app of QGIS source code contains QGIS-application-specific code, so I would say you won't find there functionality available in PyQGIS, for that you would have to have a look to the gui and core folders.

Perhaps there are other ways to set the project file programmatically from Python, but I don't know them, sorry.

Using python is it possible to call QgsEmbedLayerDialog and set the project file programmatically (mProjectFileLineEdit)?
