Hello,

I'm trying to open an attribute dialog for a temporary feature
using QgsAttributeDialog(). but with no luck. Can anyone point me to
working example?

mc = iface.mapCanvas()
layer = mc.currentLayer()
dialog = QgsAttributeDialog(layer, temp_feature)
dialog.show()

that gives me the following error on the 3rd line:

NameError: name 'QgsAttributeDialog' is not defined

Thanks,

Alexandre

I think you should to import the class before and setting the feature
owner bool parameter.
after this changes the snippet should work fine for you!

Hello Salvatore,

You were right, I just needed to import the class first, this have opened
the form for me:

from qgis.gui import QgsAttributeDialog

mc = iface.mapCanvas()
layer = mc.currentLayer()
temp_feature.setAttributes(attributes)
dialog = QgsAttributeDialog(layer, temp_feature, True)
dialog.show()

But now I can't make it editable.

All I can do is cancel the dialog.

Thanks for your help,

Alexandre Neto

is your layer editable? you need to call startEditing() method in
order to get the form in edit mode.

Hi Alexandre,

What you did is just the building of the form, you don't have all the
stuff around to make editable/uneditable and update the layer.

If you want to open a feature form like doing it from QGIS, just run:

iface.openFeatureForm(layer, feature, false, true/false)

Cheers,

Denis

Actually this how my plugin worked back in QGIS 2.2. But in the latest
versions the iface.openFeatureForm() is always in add mode (like
setIsAddDialog
<http://qgis.org/api/classQgsAttributeDialog.html#a2fbbff1c23be058caa26cc5aaf7040e8>).
That is, after accepting the dialog, it adds a new feature, and does not
update my temporary feature. This leaves no room for any changes before the
feature commit. I described my problem in the following bug report, and
Matthias Kuhn adviced me to create my own Dialog, so that's what I'm trying
to do. I would be glad to use iface.openFeatureForm() only

https://hub.qgis.org/issues/11099

Thanks for your help

I found this thread very helpful. It seems to be that to the dialog into edit mode this has to be done programmatically by calling startEditing() - not by simply having the layer in edit mode. Can anyone else verify that? Regardless, thanks for the pointers and suggestions in the thread. Much appreciated.

Hello,

even calling startEditing() programmatically, I don't seem to be able to
open the Form in editable mode.

Any help with this will be appreciated

Thanks,

I found that I had to invoke the feature form myself to get the form into edit mode.

layer.startEditing()
self.iface.openFeatureForm(layer, feature, True)

It was not enough to invoke startEditing from within the feature form init method.

Am not sure if this is by design.

Here's a crude PHP script to login and upload your <plugin>.zip file when it's been updated.

Requires libcurl

https://github.com/nzfarmer1/qgisplugintools/blob/master/upload.php

p.s. have just made a new release of TelemetryLayer - starting to get down to a short list issues that could use a more experienced plugin developer if anyone's keen ... ? :)

There
is already a make option for this: perhaps it is not easy enough
to find?

All the best.

Feel free to see a working example in the latest release of TelemetryLayer

https://github.com/nzfarmer1/telemetrylayer/blob/master/tlbrokerconfig.py (Line : 143)

If you install the plugin you can see it working by double clicking a group in the legend.

There's also an example showing how to wrap the dialog init within a class with state and to reflect dynamic changes made to the features while the dialog is open

https://github.com/nzfarmer1/telemetrylayer/blob/master/featureforms/editformfactory.py
https://github.com/nzfarmer1/telemetrylayer/blob/master/tltopicmanager.py

(Code's a bit rough as this is a work in progress)

I wanted to give an update on this.

Use case 1:
- Store a reference to the feature in the data portion of a QWidget
- On a callback, make the layer editable and pass the stored feature to the openFeatureForm

This works and enabled the feature to be edited. HOWEVER, the feature may already have been changed so could be in a stale state.

Use case 2:
- On the same call back, look up the new feature using layer.getFeatures()
- Make the layer editable and pass the "returned" feature to the openFeatureForm

This fails. Feature form opens as non editable.

Use case 3:
- Use the original feature.
- Copy the attributes from layer.getFeatures() to ensure the old feature is in sync.
- Make the layer editable and pass the "updated" feature to the openFeatureForm

This appears to work ok. See issue raised here:

https://hub.qgis.org/issues/11395

Telemetry Layer has been updated to support the working scenario:
