Hello,
a while ago I was asked to develop an app in QT and being new to it I've done some things poorly.
One of those things was to draw a graph..
At first I did this by just adding QFrames with backgrounds and used fixed calculated positions.
Now I wanted to do this with a layout, so that their positions would be calculated automatically and resize of widgets wouldnt be a problem.
I then added QHBoxLayout but then the 'poles' of the graph were centered vertically instead of the bottom..
After that I tried using QGraphicScene with the anchor property of QGraphicsView set to bottom but I'm still not getting results.
How should I go about drawing a simple graph?
Btw, some extra question of things I had in mind:
1. Are there spacers you can use with QGraphicScene?
2. Do you always need to hide and show a window in order to draw to it?
Would really appreciate some help, thanks!
