In OSX they work pretty good, in windows you really suffer. The driver works fine for several non-Qt apps (Adobe Suite works just fine) 0) It's not a driver issue 1) Wacom support is broken in Qt, several bugs are closely related 2) QtCreator, qmlpuppet and every single Qt App is affected by bugs right now 3) There is no official Wacom support 4) Few % of Qt apps are in fact targeting Wacom 5) Nobody cares about Wacom anyway, or the bug should be solved by now (some bugs are 2+ years old) 6) Digia wrote a patch, but it's a hack and was rejected 7) There are examples showcasing Qt's Wacom support but this is not true, Wacom is broken, nobody complains because 5) Huh? I don't follow you here. I'm sure Krita isn't the only Qt application that needs tablet support. This list looks to me like a mish-mash of things that aren't a reason from dropping wacom support at all and things that aren't true or relevant. Another point to consider: 1) Quick 2.0 is the way to go, but it targets designers 2) Designers use mostly Adobe suite and other similar tools (this means probably Wacoms in there) 3) Even with the Wacom unplugged the bugs are present, killing the usefulness of even QtCreator 4) Many scenarios will pop where designers+coders work in the same workstations 5) These wacom problems will become common as time passes Myself have a room with 40+ workstations where the driver is installed/uninstalled at least once a week, it's a nightmare. Huh? Qt Creator works fine here... And I've got a wacom plugged in all the time. You seem to be saying that people designing an application with Qt Creator have trouble because they have a wacom attached, and that that's a reason Qt should drop its tablet support? That sounds weird to me. Is it better to remove Wacom for Qt5? what do you think? I think that would be utterly disastrous. I haven't tried porting Krita to Qt5 yet, but for me on Windows and Linux, Qt's wacom support is good enough to write big, complex applications like Krita. Sure, there are bugs, though most problems I encounter come from Ubuntu patching stuff for multitouch support. But I am sure I would have more bugs if I tried to do tablet handling on my own, like in the Qt 3.x days. And what are you going to do with api's like QTabletEvent? Remove those as well? I thought that moving to Qt5 was supposed to be smooth and easy.

Re: [Development] Removing Wacom support in Qt5
About the state of QTabletEvent in Qt 5: For platforms other than xcb this event will never be delivered. To be on par with Qt 4 somebody needs to step up and add support for Windows and OS X. The support on QPA level is there in QWindowSystemInterface, now it's up to the platform plugins to do something with it. On Linux, QTabletEvents are supported, I added this a few months back using my Wacom Bamboo. It should be considered experimental though. Event delivery, position and pressure, proximity enter/leave seem to work. Other things (e.g. additional properties like tilt which I cannot test with the Bamboo) may not.

Re: [Development] Removing Wacom support in Qt5
0) It's not a driver issue 1) Wacom support is broken in Qt, several bugs are closely related 2) QtCreator, qmlpuppet and every single Qt App is affected by bugs right now What do you mean by qmlpuppet? We have had a commercial QML application based on Qt 4.8 up and running fine on a wacom powered roughbook. Issues like the ones with QtCreator is not a good reason enough to me to drop from Qt. 3) There is no official Wacom support As Boudewijn said, it is not so costy to get a device. I hope Digia or someone else can stand up to get this supported officially for those situations where it does not work. 4) Few % of Qt apps are in fact targeting Wacom 5) Nobody cares about Wacom anyway, or the bug should be solved by now (some bugs are 2+ years old) We do care, but it just worked for us.

[Development] Qt 5, QOpenGLFunctions
Hi everybody, did anyone try to use the QOpenGLFunctions object. I'm currently struggling with uploading my custom texture (simple uchar array) to the fragment shader. The problem is the following: As there is no solution via the QSGShaderProgram yet, I tried to use QOpenGLFunctions as it is described and explained here (http://qt-project.org/doc/qt-5.0/qopenglfunctions.html#openGLFeatures) and as it is used by the ShaderProgram anyway. Unfortunately the glBindTexture(...) method is not declared in the header, it is just missing. Does anyone know whether this is intended (then the example in the api should be changed I think) or was it accidentally forgotten? There are also some other important functions from the OpenGL ES standard missing, I think. Did someone already address this problem?

If as one of the bugs says, there is actually a full-screen invisible window just to catch all the tablet events, I wonder if the API is so clunky that such hacks are necessary, or just used to be necessary and now we need to completely rethink it.

I know that my contributions so far have mostly been to QtCore, and I'm still interested in contributing there, since I have a strong personal interest in multithreading and C++11, but I also see that QtWidgets could do with a bit of TLC, and I feel more at home here than, say, QtQuick. As most of you will know, at the QtCS, KDAB promised to produce a QtWidgets maintainer. I've talked with Till and other KDABians, and I have been ensured of their full support on this. So I guess the question now becomes: would you, the community, have me? :) Great to hear you're stepping up. My only worry is that the widget cluster is a big beast. Even with item views carved out it's rather large. In that respect I really want to find someone else in addition that would take over some parts and share the load (I'm actually looking around currently…).

[Development] Failed to start video surface on QML
Hi, I am starting to study QML. I make a simple application to play a video
with QtMultimediaKit, it does nothing, printing the message failed to start
video surface, then the video keeps on black. Following the source code:
import QtQuick 1.1
import QtMultimediaKit 1.1
Item {
width: 410; height: 210
Video {
id: videoW
source: /media/Datos/Media/Videos/Series/Hunter x Hunter/hunter.avi
x: 5; y: 5; height: 200
width: 400
}
}
Im using Ubuntu 12.4 with Qt 4.8.1.

I'm confused? Are you working with 4.8 or with Qt5? In Qt 4.8, we used to disable c++11 support for webkit and javascriptcore, because there where too many errors upstream with C++11 at the time. Maybe it is no logner true for webkit, but the JavaScriptCore of QtScript has not been updated (and will not). So it is still the case in Qt5.
