Double Clicking on a phone
Joshua Grauman
I'm wondering if there is any way to change double click sensitivity
in Qt/Android? It usually takes me at least 10 times to get a double
click to register on my phone due to using a touch screen rather than
a mouse. I'm assuming I'm not clicking in the exact same spot both
times and so it doesn't register. Is there any way to make the radius
larger of what is considered the same spot for a double click? Also,
is there any *Qt-system-wide* way to implement a long-click, to
trigger a double click event? Thanks for any hints!

Hi Josh I m very interested in the fouble click issue as well since i ve the same problem with my app.
I succesfully implemented longclick with qtgestures. Look at https://github.com/qgis/Quantum-GIS/blob/master/src/app/qgisapp.h
Qttapanholdgesture is the keyword

click percentage quite a bit better. It's sort of a skill to acquire.
However, I still think it would be really nice to be able to lower the
sensitivity.

Usually, "double tap" is not implemented on mobiles like on Desktop...
When "double tap" is used on mobile, it works like this:
- First tap, select the item
- Second tap activates it
and this behaviour is expected ONLY for items which do not get
"activated" on single tap.
Basically it's not a double click but a "tap and tap again" which does
not rerquire sensitivy, since the second tap can occur at amy time.
I would definitely NOT rely on double click as on desktop because users
will not feel it familiar on mobile.
I had at least this experience on Nokia (Synbian), and i find it
similar on Android.

Well what about double click zoom in in google maps?

Zoom is expected to be pinch zoom...
it's ok to add an additional gesture like this, but you need a more
§"mobile" primary in my opinion...

I have pinch zoom, but i find myself using very often the double tap gesture on google maps, foremost when using my phone one handed.

specialized app and not intended for the general public. Those who
want to use it I'm sure will be willing to use some non-standard
interfaces for mobile, as long as things work reasonably well. It
actually works pretty well just recompiling. There's no way I'm going
to be able to redesign the entire interface, so I'm trying to make
minor tweaks here or there to make it run better on Android. Double
clicking actually works just recompiling, but changing the sensitivity
could make it much more usable. Thanks!

to do anything in my app. Maybe it's simply a matter of the double
click interval being too fast? Looking at the Qt source, it doesn't
look like any sort of distance/radius sensitivity is programmed in. So
I'm thinking now it's just simply a matter of needing to use a slower
double click interval. Does anyone have any thoughts about this?
Thanks!

doesn't look like that is the case...
