Context sensitive help

[wysota]

There is QHelpEvent and QWhatsThisClickedEvent and QAssistantClient. If you want to keep all the help related code in one place, I suggest you do it in the application object as all events pass through QCoreApplication. Global coordinates may help you pinpoint the widget under cursor or you may install an event filter somewhere to gather and handle all help events in one place.

Of course the simplest way is just to use What's This architecture.

First of all, sorry for not being clear enough.

I have "what's this" texts and tool tips set all around, but that's not what I was talking about when referring to "context sensitive help". What I was talking about was indeed about using QAssistantClient as providing some more verbal help.

One could catch for example key press event for F1 at the application level and launch the Assistant and/or switch the page when required. I though creating a QShortcut with key sequence of QKeySequence::HelpContents was the correct cross-platform approach for triggering the help.

All the context sensitive help related code for finding the correct page in the help documentation is already done at application level, in a QApplication subclass. As mentioned earlier, the correct help page for Assistant is determined according to the current widget (or it's parent / grand parents) containing the focus.

The only problem is that the slot containing the help functionality in the QApplication subclass is not triggered whenever a modal dialog is active. Otherwise it's working as desired.
