when adding GD&T statements as described in https://wiki.freecadweb.org/TechDraw_Geometric_dimensioning_and_tolerancing
You will quickly get a lot of balloons and it is then very tiring to be forced to first select a balloon with a single-click in the drawing, then go to the model tree and there double-click to get the dialog.
This PR also removes unused includes from the dialog code.
the common rule is that if a dimension has equal over- and undertolerance, they are output on the same line as the dimension concatenated using the ± character.
This PR does this.
Note that this is not just cosmetics, it is even standardized in the GD&T norms.
also:
* use one format specifier for tolerances since the norms don't allow a different format for the over- and the undertolerance
* some code optimizations like a self-explaining function name, remove unnecessary/outdated comments
===============================================
Before this implementation, specific status via former mergeOverlayIcon() was greyed out
with the visibility.
With this commit, the developer has two options:
a) override mergeGreyableOverlayIcons, in which case the overlay will
be greyed out when the item is greyed out as per former mergeOverlayIcon()
b) override mergeColorfulOverlayIcons, in which case the overlay will
be superimposed after the icon is greyed out as it is the case for stardard
error and recompute flags.
2 weeks ago the properties EndTypeScale and LineVisible were added but not to the dialog.
This PR adds them t the balloon dialog-
It also took the opportunity to cleanup the code:
- add missing tooltips
- uniform tooltips in App and Gui
- uniform the UI element names
as reported here: https://forum.freecadweb.org/viewtopic.php?f=35&t=53664 the balloon text separation no longer works.
The regression was introduced by commit 76357b3fc . The mistake thereby was that the textHeight is already handled before the separators and that rectangular balloons behave differently because of the separator feature.
as discussed here: https://forum.freecadweb.org/viewtopic.php?f=35&t=53680&p=461356#p461349
* change default tolerance scale to 0.8
* the tolerance scale is directly applied, thus it must have non-italic label
* move tolerance scale to "Dimensions" tab
* move Fuzz settings to "Advanced" tab
* move Conventions to General tab since e.g. the projection angle is an important general setting
* add a note for the label font that this is also used for dimensions and that it there only has an effect for new ones
* use more useful step size of 0.1 for some scaling spinboxes
* sort UI fields in the C++ code to avoid doubled or missing entries (there were 2 doubled entries)
* uniform width of all preferences dialogs
* better alignment for the HLR dialog
Add the optional Qt::MSWindowsFixedSizeDialogHint parameter to all uses of the QInputDialog::getX static functions to silence a Qt/Windows debug mode warning about QWindowsWindow::setGeometry: Unable to set geometry. Increase the size of the unit calculator to eliminate the same warning. Finally, call adjustSize() on the "Unsaved Changes" dialog to silence the warning.
When exporting a hidden TechDraw::Page with exportPageAs[Pdf|SVG] a
Segmentation Fault occured.
The return value of getMDIViewPage() was only checked for the first call, but
not for the second call. showMDIViewPage() silently returns, when the
TechDraw::Page is hidden and does not load the page.
At the moment one has to specify the LineGroup as string. But one doesn't know what groups exist. So one has to check the Wiki, learn there where the groups are defined and then open the definition file with a text editor.
This PR simplifies this by reading the existing groups out of the definition file and fill the combobox accordingly.
It also give the user info what the selected LineGroup defines via the tooltip.
A nice side effect is that no typos can occur since you don't have to enter the LineGroup name as text.
