Because Gui::ViewProviderLink can be used to override the view provider
of any object, it is not safe to assume view provider type without
explicit checking.
- indicate if one is in the Box Selection mode
- get rid on dialog if one really wants to cancel (no other Task dialog does this and it is annoying)
- fix clumsy dialog layout
When modifying primitives in complex geometries having a recompute for every keystroke can be annoying. Disabling keyboardTracking fixes this but keeps the immediate preview when using the spin buttons.
An empty block after a conditional can be a sign of an omission and can decrease maintainability of the code.
Such blocks should contain an explanatory comment to aid future maintainers.
If a body is in a Part container and a new primitive is created no preview is shown because the Part container is automatically made invisiible.
The user has to manually make the container visible but this is an error-prone procedure because the Attachment dialog reacts on user-selection and thus
unintended things can happen. So, this is a serious regression of usability.
The regression is caused by commit a06e0b7c2d but the commit log doesn't explain why the change was even needed.
So, this commit leaves the previous changes but re-adds the old check to filter out container objects.
Rename Python variable 'tv' to avoid potential conflict with others
(PS. I can't reproduce error caused by this. But there is no harm doing
it either).
Handle editing attachment through an App::Link.
for faulty geometry output, The user can still see all the error output in the task panel but by default they will see nothing in the Report View as Log is not Enabled for new users. See discussion https://forum.freecadweb.org/viewtopic.php?f=15&t=46803#p402533
========================================
1. The Grid has a default maximum of 10000 lines that is controlled via a new property. The grid is not created (is empty)
if a higher number of lines is necessary. This event is show as a Warning in the Report view.
2. The Grid now checks a new property ShowOnlyInEditMode before deciding whether to show the grid or not. This is a new
mode for ViewProvider2D and derived objects. If the property is set to true (and showGrid is true), the grid is only shown
if the object is in edit mode. If the property is set to false, the grid is shown regardless of whether it is in edit mode
or not (provided that showGrid is true).
3. Grid limits are now encapsulated (private). They can be set via a new function updateGridExtent.
