My thinking here is whether this needs to be supported officially -
e.g. by making the panel wider by default. Alternatively we could add
a method to QgsProcessingAlgorithmDialogBase to handle resizing of
this panel.

Heck yes! There's a TON of work which processing would greatly benefit
from. Here's a very short brain-dump of potential high-value projects:

- if you're a user of any of the 3rd party providers (GDAL, GRASS,
SAGA), these need a lot of love. There's lots of open tickets against
them, some of which would be quick fixes for someone more familiar
with the underlying provider library. Similarly if you're on Win or
OSX there's quite a few open tickets against these providers (most
testing is done on Linux)

- if you're a model user, a nice project would be improving the inputs
panel in the modeler dialog. It's been discussed (somewhere, can't
find it now) that this panel should be reworked to be a list of inputs
used within the model, with + / - buttons to add a new input and
remove a selected input. And then we could add up/down buttons to
allow inputs to be reordered for models, since they are currently just
shown in a semi-random order and there's no way for users to
reorganize them logically. All the API stuff should be in place for
this, it's just Python GUI work that's needed.

- another high value task is porting the QGIS algorithms from Python
to c++ (for speed and stability). At the same time we do this we
upgrade each algorithm to support "data defined" parameter values
(e.g. buffer width based on expressions!). The goal here is to move
all the QGIS algorithms across to c++, EXCEPT those which have
dependencies on Python libraries.

- there's rough notes on
https://github.com/nyalldawson/QGIS/wiki/Processing-Algorithm-Bugs-and-Enhancements
concerning improvements we can make to existing algorithms which would
be fantastic to see explored

- Or, the funnest processing job, adding more algorithms! There's a
rough wish-list at
https://github.com/nyalldawson/QGIS/wiki/Algorithm-hit-list , some of
which are just a matter of exposing existing QgsGeometry methods as
processing algorithms (e.g. exposing QgsGeometry::transform(
QTransform  ) as an algorithm to allow rotate/shear/scale
transforms), and some of which require adding wrappers to GEOS
functions to QgsGeometry (GEOSMinimumWidth_r,
GEOSMinimumClearanceLine_r, GEOSNode_r, GEOSSharedPaths_r) and then
exposing as processing algorithms. Others need javascript->c++ ports
of functionality from turf/mapbox js libraries, if that kind of thing
interests you.

I'm happy to mentor. Just let me know.

Re: [QGIS-Developer] QGIS3 plugin migration issue

[André William]

Thank you Nyall, I understand.
The reason I needed to resize the window was to better fit some image
content in my HTML help.

Taking the opportunity, I'm a C++ and Python developer and I would love to
contribute on the project. Is there any need for help in the Processing
Framework (since I'm already a bit familiar with it) or in others areas? I
would probably need some guidance at first but I've been using QGIS and
developing plugins for some time now, so I guess it wouldn't be too big a
learning curve.

Re: [QGIS-Developer] Custom widgets and Qt Designer 4 and 5

[Etienne Trimaille]

Hi Matteo,

I'm finally trying to use custom widgets from QT Creator instead of using
promoted widgets.
I'm facing the same issue with the generated path. It's not using
"qgis.gui" so it's failing during the import in QGIS.

Did you fix this issue?
I can manually fix these imports, but I'm asking if there is a fix for
that. Thanks

Re: [QGIS-Developer] GDAL 2.2.4 Python 3.6.4 Install error in Mac OS X El Capitan (10.11.6) and QGIS3.0 : setup.py and gdal-config errors

[William Kyngesburye]

Well, you shouldn't be installing GDAL-python from pip if you're using my GDAL 
framework and QGIS3.  My GDAL framework has the python module linked into the 
python site-packages.

But, I can see a problem that I should fix - pip doesn't see my gdal-python, so 
other modules that need GDAL will want to install GDAL from pip (this may be 
why you were doing this).  I ran into this with the proj module, so I created a 
wheel for that so pip sees it.  I need to do the same for GDAL, and Shapely 
(GEOS).

Hi all.
Sorry, I asked Admire from Kartoza to help me in this period, he might have 
overlooked this one.
Done now.
Thanks for your patience.

This would be the way I prefer, or include that same "widgetery" in the
layout properties. The "current" page could update based on the portion of
layout that is visible, as already happens for the grids panel.

I love the idea of having a list of available templates with some
thumbnails. But it won't fix the issue of not being trivial to see a pages
properties once te layout is created.

Re: [QGIS-Developer] GDAL 2.2.4 Python 3.6.4 Install error in Mac OS X El Capitan (10.11.6) and QGIS3.0 : setup.py and gdal-config errors

[Noli Sicad]

Disregard this error.

The processing plugin loads now properly.

I think downloaded and installed the wrong version (32bit / 10.6) of
the python3.6.x. instead of 64bit / 10.9). It seems that python 3.6.5
is properly installed now.

Re: [QGIS-Developer] [Qgis-user] QGIS 3 Print Composer - Page Properties

[Tom Chadwin]

I've only recently looked at layouts, so apologies if this is not helpful.
How about, in the right-hand tab of the right-hand menu (is it called
Items?), there is a permanent item, perhaps in italics, called Page, and at
the top of that panel, some indication of which page is currently selected?
You could then change which page is selected by clicking any item on it.

This would then mean that the second tab could be used for page properties
as it is for item properties. 

Tom
