Re: [QGIS-Developer] Problems configuring the statusBar

[WhereGroup]

Hey AF,

oh, looks like the help() for those Qt objects is not as comprehensive 
as I hoped.


>>> type(iface.mainWindow().statusBar())


https://doc.qt.io/qt-5/qstatusbar.html ->
https://doc.qt.io/qt-5/qstatusbar-members.html ->
https://doc.qt.io/qt-5/qwidget.html#styleSheet-prop

>>> iface.mainWindow().statusBar().setStyleSheet("background-color:red;")

Now my status bar is red.

No idea about fonts...

Have fun!

Hello Johannes,
Querying was how I found the method 
self.iface.mainWindow().statusBar().styleSheet() along with many 
others. I circled back and tried to use 'help' to figure out what I 
was missing. However, help for 
self.iface.mainWindow().statusBar().styleSheet() only tells me that 
styleSheet is a method of the self.iface.mainWindow.statusBar instance 
that returns a string. I also explored another method 
self.iface.mainWindow().statusBar().setFont(), which is supposed to 
take a QFont, but I still haven't been able to make it work properly 
either.
The bottom line is that I can add widgets to the statusBar and style 
them, but even changing the font type for the whole statusBar remains 
elusive. At least this route allows me to move on with the project 
while I figure out all the other details.

Thanks,
AF

Hi  AF,

you can always query objects for their type with type(objectname) or 
even access their documentation in an interactive interpreter session 
with help(objectname). Then you know what methods and attributes they 
expose or which Qt documentation page is matching whatever object you 
are handling.


Be aware that pages like https://doc.qt.io/qt-5/qstatusbar.html only 
list the "direct" members and that the objects might have already 
inherited others. For that you can click the "List of all members, 
including inherited members" link.


CaSe matters! Best use an IDE that helps you with autocompletion and 
inspection, this helps a lot when learning. For PyCharm all you need to 
do is select the python-qgis.bat file as interpreter and let it scan the 
Python modules for a while.


When googling for QGIS Python classes, make sure you are reading 
up-to-date documentation matching your QGIS version, e. g. 
https://qgis.org/pyqgis/3.28/gui/QgisInterface.html


Cheers, Hannes

Hi Nyall,
Obviously I'm not an expert in Qt/QGIS (only been using it for a few 
weeks) and still have many things to learn. Most of the code works 
fine (by staying away from very complex structures) and styling 
widgets has been no problem until now when trying to do anything with 
the statusBar. From your comment, I went back to the 
PyQGISDeveloperCookbook(v3.22) and snippets like
    myicon = 
QIcon("/home/ubuntu/.local/share/QGIS/QGIS3/profiles/default/python/plugins/app/appicon.png")

iface.mainWindow().setWindowIcon(myicon)
iface.mainWindow().setWindowTitle("Tailoring QGIS")
had worked in the past. One problem has been to find specific 
documentation about iface.mainWindow().statusBar(), let alone examples 
and those online (e.g. 
https://gis.stackexchange.com/questions/210327/how-to-display-qgis-processing-bar-from-a-plugin) 
kind of suggests that my initial snippet could work. I'll continue 
reading the cookbook tomorrow but, in the meantime, is there any other 
documentation discussing iface in general or 
iface.mainWindow().statusBar() that I should also be reading? (Note: I 
also checked https://doc.qt.io/qt-5/qstatusbar.html)

Thanks,

P.S. Again sorry about the extra messages that shouldn't have been 
sent to the thread (hopefully it won't happen again)

Re: [QGIS-Developer] Problems configuring the statusBar

Hello Andrea,
Sorry for the delay as it has been a busy Sunday with several commitments.
I've been trying to implement your proposed solution using different
approaches but still unsucessfully (even after trying different
combinations). From several posts, a potential syntax would be something
like:
variable1 = self.iface.mainWindow().statusBar().styleSheet()
variable1.setstyleSheet("background-color: black;")
However, this is not effective and 'variable' is returning
QStatusBar::item{border: none;}, which I'm unsure how to intepret or how to
define the variable so that setstyleSheet can be applied.
I also tried a more simplified version (following the suggestion at
https://stackoverflow.com/questions/23490017/how-to-add-style-via-setstylesheet-without-losing-orignal-style-in-qt):

setstyleSheet("background-color: black;")
self.iface.mainWindow().statusBar().styleSheet()
However, it returns 'setstyleSheet' is not defined so it doesn't seem to
take setstyleSheet w/o an assignment. Do you have any suggestion on how you
would proceed?
Thanks,
AF
P.S. My apologies for the previous reply (it didn't go as anticipated)

Respectfully, your code has many fundamental issues. I would suggest
reading the qt documentation and getting a better grasp on qt and the qt
API before attempting to write this script.

This will output the string. However, doing anything of substance (e.g.

Hi AF,
maybe you need to use setStyleSheet(const QString ) to set a 
style sheet.
