Find the .xml file that describes the Qt label GRC block – it's very likely in gnuradio/gr-qtgui/grc – copy and modify it to your needs :) That way, you can have your own "image label". GNU Radio as project certainly wouldn't mind getting that new XML file as addition, neither :)

Hi Marcus,

I already got the Qt Label to show an image by editing the python file that GRC creates. The problem is that if I want to use GRC “interactively” to change parameters/settings/etc. that’s not available in the GUI I create then the python file is overwritten by GRC. So I was just wondering if there was a way inside of GNU Radio to use the Qt Label widget to display an image file. Thinking about it may be I could use an embedded python block or module – I’ll have to look into that.

 

Thanks,

 

Tim

Hi Timothy,

hm, basically, all the Qt GUI things are really Qt QWidgets and subclasses. The python file generated by GRC sets up the window and stuff. I think the quickest way of understanding how this all works together is making a small Qt-GUI-based flow graph, and diff'ing the python code before and after you add a Qt Label. You might be able to add a picture label just the same way.

If you haven't noticed these before: you can basically configure a grid layout by filing the "gui hint" field in the Qt GUI blocks with "row,col,rowspan,colspan", where rows and columns start with 0.

Best regards,

Marcus

Hi,

I am using GRC to create a flow graph that has a GUI and I’m looking for a way to add an image (a logo) to the GUI. Is there a way to use one of the Qt GUI widgets to add an image file? I know I can edit the python file created by GRC and add image file where I want but I think if I’m using GRC to make changes it will overwrite my modifications to the python file.

 

Thanks,
