Change pressAndHold Timeout

Schneidi

Hi,

i use the MouseAreas pressAndHold signal alot for drag and drop purposes.
The docs say that the timerout is currently set to 800 ms. But i couldn't find a way to
change the time after that the signal is emitted.

Is there a way to change that ?

Because if you have a lot of drag and drop going on the timeout seems a bit anoying.

Thanks guys.

You implement drag and drop by your own? Why you don't use drag property? Or is there also a timeout to start the drag?

Schneidi

I had to implement it by my own because of my application structure.
I couldn't just drag an object around because I had to drop it to completely different object structures. Thats why i instantiate dedicated drag objects.

Its a bit tricky to explain.

So I used the pressAndHold signal to create a new draggable object.

Hmmm, ok and what if you implement this also by your own? With pressed signal start a timer, with released stop it. And if the timer has a value that you like, send your own signal?

Schneidi

ok that is one way to do it. so if there is no way to just change the timeout i could go to every part for the drag and drop handling and do it all by hand.

Hi,

From a quick look at the source code, it seems to be a hardcoded value

Where i can find the source? Sorry but every time i google for MouseArea only found examples but not the source itself.

Seems already requested. Check "this":https://bugreports.qt-project.org/browse/QTBUG-24793

bq. Where i can find the source?

If you have source installed, goto <QtDir>/5.3/Src/qtbase/src/gui/kernel/qplatformtheme.cpp and check QPlatformTheme::defaultThemeHint(ThemeHint hint)

Thanks SGaist,

you're right its still hard coded.

case MousePressAndHoldInterval:
    return QVariant(800);

It would be nice if we were be to customize these settings in a future release.
Because they have a huge impact on the user experience.

To bad that this can't be overwritten.
Guess i have to wait for a user response to decide whether or not i'm going to implement this all by myself.

Thanks guys.
