When reading and comparing Qt5-docs and Qt6-docs, I read,
that there are no differences in the functions!
So it is not necessary to have the differentiation
between the Qt-Versions.
Code compiles without errors or warnings for Qt5 and Qt6.
Maybe not (yet) perfect, but it looks pretty good to me!
Why am I doing this to myself?
All this crap with fonts and stuff!
It's been crap for as long as I can remember.
Now that the problem with the translations of keyboard shortcuts has been resolved and rotation using the space bar works reliably in principle, I took a closer look at the rotation function itself in the element editor.
I noticed, for example, that arcs can be rotated at an angle of 15°. This doesn't really make sense, as the “arc” part doesn't have the “rotation” property. There is only width and height.
And somehow rotating arcs didn't work well: start- and span-angles weren't adjusted.
Lines and polygons can be rotated in 15° increments, which doesn't make much sense, if other parts that can only be rotated in 90° increments are selected at the same time.
To make a long story short:
I reworked the rotation functions of the graphical parts so that now all parts are rotated in 90° steps around the origin! This means that it is now possible to mark several parts and rotate them around the same point at the same time!
In addition, the functions for mirroring graphic parts at y-axis (shortcut "M") and flipping at x-axis (shortcut "F") have been implemented.
I have saved the text elements for later!
(or someone else)
If the version number of QElectroTech is requested in the forum in case of error messages or anomalies, the Qt version used is very often stated because the entry “About QElectroTech” does not appear very prominently in the help menu: The entry “About Qt” is used much more frequently because it appears eye-catchingly as the lowest entry. However, specifying the Qt version is often not helpful for troubleshooting: We need the QET version!
That's why I'm moving the “About QElectroTech” entry to the bottom, so that it is easier to see and find!
