[Interest] expanda tab depending of QTabWidget

[Freddy Martinez Garcia]

Hi guys, I don’t know how ask this question, even ai don’t know how really I 
nee to looking for because I don’t know what’s the name of the QTabWidget 
property which let me as Finder does in OS X.

In OS X, if you create a new tab, we could see that each tab is expanding in 
the entire width of the application, it’s mean that if I have 3 tabs, the width 
of each tab will be the width of the QTabWidget / 3

Has Qt any way to do that ? 

regards

Thanks for the info. My app is used in rural and areas with low connectivity 
and needs to upload a lot of data. I was just looking to get an idea if they 
are having signal issues or some other kind of issue. My current MO is to get 
the GPS location then look it up on OpenSignalMaps, and deduce what their 
signal should be. It's not a complete database. So I was hoping the signal info 
could also be used to trigger an attempt when it got a "good enough" signal.

[Interest] No resize after hiding the navigation bar on Android under QML.

[Tr3wory]

Hi all,

I have a full screen QML application on Android.
I create a QQuickView in main() and use showFullscreen() to show it.

On my Samsung phone (with physical navigation buttons) everything is fine,
the status bar gets hidden, and my application uses the full area of the
screen.

On my Nexus (with on-screen navigation bar) the status bar and the
navigation bar gets hidden, but my application does not use the full
screen, the area under the (now hidden) navigation bar is light gray, and
unusable.

After some research, it looks like in native Android code I would need to
set the system ui visibility to
SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |
SYSTEM_UI_FLAG_LAYOUT_STABLE,
but I can't find a way to do that from Qt.

Does anybody faced the same problem?

Best,
tr3w

Re: [Interest] Probable Qt bug in widgets display

This looks like a paint bug to me. The best way forward for you is to 
create a small self contained application that shows the problem. In 
this case, it should probably be possible to do it in 10 lines of code 
or so. And then add a description on how to reproduce it. Create a bug 
report with those two things.


The good thing about the small test case is that you also make it very 
clear if it really is a Qt bug or if you did something on your side that 
triggers it.

Here are two screenshots:

It seems this also happens with windows RDP sessions.

[Interest] qdoc: dynamically change index file's URL

[Lorenz Haas]

Hi,

currently I use qdoc for my custom project and link against Qt classes
with --indexdir + depends. This is working fine, however, the URLs in
the Qt index files (from the default Qt installer) are
"http://doc.qt.io/qt-5;.

Now I want to create my documentation to use inside Qt Creator and
thus the URLs should be like "qthelp://org.qt-project.qtcore/qtcore/".
Is there any way to do so from _inside_ the qdocconf file since I do
not want to alter the original Qt index files.


Thanks

Lorenz
