tdf#130857 qt weld: Support Math's "Spacing" dialog
for the case of using native widgets with the qt6 VCL plugin:
> Currently, the image isn't always updated when choosing
> a different category via "Category" menu button. This
> will be addressed in a separate commit.
For some reason (not further analyzed so far), no
QApplication::focusChanged signal gets emitted (that would then
trigger the slot in QtInstanceWidget::applicationFocusChanged)
for the following scenario:
* start Math with the qt6 VCL plugin and environment variable
SAL_VCL_QT_USE_WELDED_WIDGETS=1 set
* open the "Format" -> "Spacing" dialog
* while the focus is still on the "Spacing" spinbox, click the
"Category" menu button and select another category, e.g. "Operators"
The problem cannot be observed when first moving focus away
from the "Spacing" spinbox.
To make sure the image gets updated, explicitly call
the SmDistanceDialog::SetCategory
Call the `GetFocusHdl` handler in SmDistanceDialog::SetCategory
after setting focus to the spinbutton which makes this work
for the case of using native widgets with qt6 as well.
