This adds a mini-framework for display of extra icons in layer tree views
next to layer and group names. Tool tip text can be associated with indicators
to give extra context for indicators. In addition, a signal gets emitted
when user clicks indicators and custom actions can be defined.
The main window's layer tree view (ToC) gets support for indicators
that are shown when a vector layer has a filter applied. This makes it easier
for users to understand that they are looking at a subset of all data.
Clicking the indicator's icon brings up query builder.
- Switch to flags instead of boolean argument
- Move logic for layer validity to canRunUsingLayer
- Add unit test
Also remove settings flag to hide duplicate features action
metadata editor to make their operation more self-explanatory
for users.
Also add tooltips to the buttons describing their function, and
allow the buttons to operate on multiple selected rows at once.
Fixes#18090
* avoid using lambdas and use dedicate class and subclasses for each widget type (lable, groupbox, tree, etc)
* this makes the code much more clearer
* allow creating custom highlight widgets with API
From the clazy docs:
"Warns when a signal, slot or invokable declaration is not using fully-qualified
type names, which will break old-style connects and interacting with QML."
This fixes an unreported bug that without detecting an
invalid input when using a comma as a decimal separator
silently converts the entered value to NULL.
Since locale support in QGIS is in its early stages
we convert commas to dots within the validator,
this is common practice in almost all web applications
where you can enter a comma instead of a dot and
the conversion appears while you digit.
This comes with brand new tests for QgsFieldValidator.
Bonus: small fix in sipify.
I realise this adds another toolbar button... but I'd strongly
argue that the toolbox is used FAR FAR more often than many of the
other toolbar actions!
Ensure that dialogs are always correctly deleted when appropriate.
Also, if an algorithm is running in a background task and hits
an error, we automatically re-show the algorithm dialog and the
associated log for debugging.
Fixes#16858
