Re: [QGIS-Developer] Customize list of algorithms shown in Vector or Raster menu

[DelazJ]

Merci Etienne. I find them.
Do you know if only Vector and Raster menus are allowed or could I set my
own main menu? (i know i can test but... :) )

Hi,

It's already possible in QGIS 2. In your processing options, you can setup
your own vector and raster menus.

[QGIS-Developer] Customize list of algorithms shown in Vector or Raster menu

[DelazJ]

Hi,

By default, some of the Processing algorithms have a shortcut in Vector or
Raster menu. Most of them are equivalent to the old Ftools or GDALTools
core plugins items.

Question: Is it (/will it be) possible for end users to extend these menus
with any of the other core algorithms? Or is that menu structure hardcoded
in QGIS (regardless what plugins can do)?

Thanks,
Harrissou

No bother at all :)

I am just playing around with some ideas for improving the WMS layer
support. The whole 'hijack QGIS native dialog' thing is just a sidetrack
that is not really my main goal. It just seemed like a wacky, fun idea to
try out. just to see if it is possible!

That might be the plan for the long run. For now I'm just having some fun
at lunch break ;)

Yeah I am aware there is a proper way to do this, and this is not it. This
is just toying and poking at stuff to see what is possible.
On a more "serious" tone, I agree with you 100%. This is not something that
I'd be putting out there for the world to use.

Re: [QGIS-Developer] Replacing a dialogue with another at runtime with Python

[Denis Rouzaud]

Hi Ricardo,

Sorry to bother, but I think this kind of hack should be discouraged.

This modifies QGIS behavior in a hidden way by replacing native dialogs.
And as you pointed, there is probably no way of uninstalling your plugin
properly. It will require QGIS to restart to work as expected, which is not
that bad, but still.

If you think current behavior is not optimal, I would suggest to either:
* bring your improvements into master instead of a plugin
* create a dedicated button and menu entry in your plugin for your
customized dialog

With the latter option, I think it would be possible to add your menu entry
and button in the layer menu and layer toolbar, respectively.

Just my two cents.

Denis

Re: [QGIS-Developer] Replacing a dialogue with another at runtime with Python

[Ricardo Filipe Soares Garcia da]

Hi all

Answering my own question for posterity

Turns out I can disconnect all slots from a signal by calling
`my_action.triggered.disconnect()` without any arguments. My goal of
replacing the native QGIS 'Add WMS/WMTS layer' dialogue with another one
can be achieved like this:

```python

def my_handler():
print("Hello")

action = iface.actionAddWmsLayer()
action.triggered.disconnect()
action.triggered.connect(my_handler)
```

This leaves another problem to be solved: How to restore the native QGIS
dialogue when my would-be plugin is deactivated by the user. The following
seems to work on QGIS 2.18:

```
provider_registry = qgis.core.QgsProviderRegistry.instance()
add_wms_dialog = provider_registry.selectWidget("wms")
action.triggered.disconnect()
action.triggered.connect(add_wms_dialog.show)

```

Best regards

​What would you think about publishing a QGIS Server update on blog.qgis.org
once the latest information has been gathered? I'd like to see Server
presented and advertised more ​widely.

​I'd be glad to help write the post if someone can help with the necessary
insights.

Anita​

[QGIS-Developer] QGIS3D in OSGeo4W

[Andreas Neumann]

Hi Windows packagers - probably Jürgen? 

Now that QGIS 3D is in master - do you plan to enable this compile
option? A requirement is the upgrade of qt to version 5.9. Do you see
any blockers upgrading to qt 5.9 or can this be done? 

Thanks for the discussion,

Hi Etienne,

from my point of view, this is the perfect time to start stressing QGIS
server 3! We just discussed bout starting working with it this morning on a
new project.

Maybe Alessandro and René-Luc can tell us more about the plugin side.

Paul is currently fixing issues raised by the OGC test engines. Richard,
could you find some time to expose them on a public url?

Régis

[QGIS-Developer] QGIS Server 3 status

[Etienne Trimaille]

Hi devs,

We would like to start testing QGIS Server 3: OGC services and Python
plugins.

I think I read that the QGIS Server refactoring was finished and it seems
that most of OGC tests are working:
http://37.187.164.233/ogc/latest_wms_1_3_0.html

Is it possible to have the status of QGIS Server 3?
Are there some major known issues? Are Python plugins fully supported? Can
we start porting plugins to the QGIS 3 Server API? Is there some highlights
to know for Python plugins?

Thanks for the all the work which has been done!

Regards,
Etienne
