Qt resource is innitialized by a static object constructor (see
https://wiki.qt.io/QtResources). When we put resources into a static
library, the linker removes that static objects and thus the resources
themselves. To correct that we append resources to the main executable
sources list. This is done via custom function qbt_target_sources which
knows where to read the executable' name.
gui/mainwindow.ui: Warning: The name 'actionExecutionLogs' (QAction) is already in use, defaulting to 'actionExecutionLogs1'.
gui/mainwindow.ui: Warning: action `actionSearch_engine' not declared
gui/mainwindow.ui: Warning: action `actionRSS_Reader' not declared
Add helper function to initialize shutdown message.
Group similar functions together.
Merge shutdown() function into its only caller.
Add override keyword
Both download handlers (in the tab and widget classes) convert model
index into an URL, set row color, and call download function.
Make the download button handler (in the SearchWidget class) call the
slot of the SearchTab class.
1. Extract "transaction" support for QSettings into separate class
TransactionalSettings.
2. Define macrto with explicit name for the case when this "transaction"
support is needed.
3. A bit optimize QHash <-> QSettings copying: replace assign with
insert() and remove repetitive key lookups.
4. In save() check dirty status before getting the lock too.
The changes from items 1 and 2 make text more structured and the logic
of the SettingsStorage class gets separated from the implementation level
task of guarding the settings serialization. The changes in 3 and 4 do not
make the app much faster, but neither make any harm to the code readability.
Since we already have searchtab.ui, let's set up all the widgets there.
Additionally, save a bit of vertical space by putting results label in
a row with the filter widgets.
