Using widget plugins in Qt Designer

[Michael DePalatis]

I would like to use the custom CurveWidget and ImageWidget plugins for Qt
Designer which seem to be defined in a "qtdesigner.ui" file (found for me
on Linux in /usr/local/lib/python2.7/dist-packages/guiqwt/tests). However,
I cannot figure out how to actually do this, and the Qt Designer
documentation that talks about plugins seems to assume I want to write my
own plugins rather than just install those written by others. It is worth
noting that with Python(x,y) in Windows, it is setup automatically to give
me these plugins. Does anyone know how I can add these on Linux?

In our library [1], we do it as follows:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
from guiqwt.qtdesigner import create_qtdesigner_plugin
PlotPlugin = create_qtdesigner_plugin("guiqwt", "guiqwt.plot",
"CurveWidget",
icon="curve.png")
ImagePlotPlugin = create_qtdesigner_plugin("guiqwt", "guiqwt.plot",
"ImageWidget",
icon="image.png")
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I hope this helps

I appear to be missing something. This creates some Python objects, but
then how do I translate this into something that Qt Designer can understand
when I'm running it by itself?

Ups..., sorry, you are right.
I forget about these details because we use a custom-modified qtdesigner
[1] that takes care of it ...

But I would say that you just need to set the PYQTDESIGNERPATH
environment variable to contain the dirs where your plugins are created
(make sure you define them in files whose name ends in "*plugin.py"). Have
a look at the QtDesigner docs:

http://pyqt.sourceforge.net/Docs/PyQt4/designer.html#writing-qt-designer-plugins
