Quick and dirty:

struct Style : QProxyStyle
{
void drawControl(ControlElement element, const QStyleOption *opt, QPainter 
*p, const QWidget *w) const
{
if (element == QStyle::CE_TabBarTab) {
QFont f = p->font();
f.setBold(true);
p->setFont(f);
}
QProxyStyle::drawControl(element, opt, p, w);
}
};

...
yourTabWidget()->tabBar()->>setStyle(new Style);


May need some polish.

I haven't actually found out how to properly link against the _
named libs yet however, because it seems when running a Qt based app,
Dalvik only provides /system/lib and /vendor/lib as library load paths and
not /vendor/lib/egl. I sent another mail to the list regarding this
specific issue a couple of days ago, but no-one has answered it yet.

 I should find it there yes. But the irony is that I can't find it anywhere. Meanwhile the Samsung has it where you would expect. I'm looking for an OpenGL for it, but the Adreno SDK doesn't have it. Any idea where I mght find it?

 

Many thanks.

You'll probably find it at /vendor/lib/libOpenCL.so.

I'm not sure which version of OpenGL ES you need, but you have both versions available to link against using the NDK at least.

I've been wanting to do a writeup on the whole QML videofilter -> OpenCL pipeline through shared GL context, but haven't really found the time. There's not that many great examples to go by out there for Android and it seems to me at least, that it's a bit of a greenfield effort, even though the Qt guys have put in some great initial building blocks.

Re: [Interest] Video Filters on Android

2018-04-04 Thread Jason H

Thanks! I'm trying to do this on a Pixel 2 XL, but there is no libOpenCL.so on it! (directory listing included later)

 

I'm searching for it. I'm looking at the Aredno SDK, 

 

I'm sort of at a loss for what all I need to include for android. You mention GLESv2, but you also mention v3.

Re: [Interest] QTimer at 30Hz interval?

2018-04-04 Thread Jason H

Easy! You can't! But you can come very close. Remember on a multitasking OS, 
you're dealing with a time division multiplexing, and a scheduler, so getting 
scheduled at 30hz is impossible. But there are a few things you can do. 

On linux you (a process) can set your priority and even scheduling method. This 
will get your jitter down. If you can always the kernel you can change the time 
size

The best thing is to use a hardware interrupt, which you may not be able to do. 

At this point I have to ask why 30Hz? 30 FPS Video is really 29.77. not many 
things are actually 30.0 hz. And not-vomiting VR takes at least 60fps.

One trick I've done to get better resolution is, if you can work with jitter, 
is to set a low timer internal and check if the accumulated interval has 
accumilated work for you. Because the timer timout waits *at least* that many 
milliseconds, being called sooner and checking for work might work better than 
always overshooting. (I actually came up with a way to saturate a CPU with 
encryption while having a UI progress bar update smoothly by letting the timer 
interval adjust itself.) You can use 1 or 0ms. With 0, your slot will be called 
by the event loop when is empty as fast as it can be called.

Using widgets? You didn't say what context.

Maybe you can set a dynamic property on the tab when you want it to be
bold, and attach a special style using properties in the stylesheet.

Yes, using widgets.

I've tried a dynamic property however as far as I can see, I can only 
set the dynamic property on the entire tab bar - not a specific tab. 
How can I set it on a specific tab?

Alternatively suffix an asterisk; Tab -> Tab*. Then remove it on highlight.

Re: [Interest] Video Filters on Android

2018-04-04 Thread René Hansen

I never got that specific example to work, but assuming you're building
with the Android NDK, you can include:

#include 
#include 

Which will give you access to *eglGetCurrentContext()*.

I'm using the r10e ndk, since that's what works with Qt at the moment. GLES
v3 is available in toolchain v21:

$ ls ~/Code/Android/android-ndk-r10e//platforms/android-21/arch-arm/usr/lib/
crtbegin_dynamic.o  libGLESv2.solibdl.so
libstdc++.a
crtbegin_so.o   libGLESv3.solibjnigraphics.so
 libstdc++.so
crtbegin_static.o   libOpenMAXAL.so liblog.so
 libthread_db.so
crtend_android.olibOpenSLES.so  libm.a
libz.a
crtend_so.o libandroid.so   libm.so
 libz.so
libEGL.so   libc.a  libm_hard.a rs
libGLESv1_CM.so libc.so libmediandk.so

If you want to link against OpenCL, you still need to pull a
*libOpenCL.so* from
an actual device though.

Re: [Interest] Home built of the "official" Maintenance Tool

2018-04-04 Thread René J . V . Bertin

OK, I figured this out. With the risk of kicking in open doors:

- the maintenancetool/MaintenanceTool binary is "just" the installerbase 
executable.
On Mac it will be modified to depend on embedded Qt frameworks by the actually 
installer when it writes the MaintenanceTool bundle, but it fails to embed 
those 
frameworks because they weren't bundled with the other installer data. 
Suggestion: use macdeployqt to create a fully functional MaintenanceTool.app 
bundle during the initial creation of the installer.

- the information required to run the MaintenanceTool on the installed software 
is expected under the same name as the tool itself.

- An up-to-date self-built MaintenanceTool.app copy will continue to fail with 
the message that it's out-of-date because the tool version is not obtained from 
the app itself, but from the database of installed items. IMHO that's an 
anomaly.

Yeah, but it doesn't have signals to fire on a timeout... 
QElapsedTimer's major purpose is measuring time, not sending (repeated) 
signals. So it's more like QTime, not like QTimer.

Re: [Interest] QTimer at 30Hz interval?

2018-04-04 Thread Konstantin Shegunov

Hi,
Just an idea:
I believe by default QTimer doesn't have that fidelity, however you can
check if your platform supports Qt::PreciseTimer and stagger two of them,
one at 30 ms, and one at 31 ms. Both would go to one handler, where you
check if the timeout has expired and trigger the needed slot on demand.

My use case is for Linux only so I'd be happy with some Linux-specific
