[Interest] system, general and fixed font on Linux

Hi, Looking at the output from the qtdiag app from a newly built Qt 5.5.0 install (installed into /opt/local), I noticed that its system, general and fixed width fonts were fonts I apparently chose one way or another, at some point in the past. Where is this information obtained from, I can't

Re: [Interest] Strategies to create dialog boxes dynamically in Qml

Hello Nuno, In finishUIDDialogCreation() (after your check for it being null) you can connect the signals you're emitting from your dialog to another function of your choice, for instance if you had a function named "handleOKClicked" then you can do this:

Re: [Interest] Qt at iOS - Custom Storyboard Launch Screen

Hi Robert, In our project, we use nearly the same method to create launch screen except that we use a .xib file to specify launch screen layout. It works well in both debug and release build. If you iphone runs iOS 9, please note that there is a bug in iOS 9 which will prevent launch

Re: [Interest] Qt at iOS - Custom Storyboard Launch Screen

Dear Liang Jian, Thank you for your input. 1. Qt-generated Debug projects: It's interesting that for Qt-generated Debug projects, it runs properly from QtCreator application run, but not in Debugger. Black screen if running such projects from Xcode. 2. Qt-generated Release projects: Launch

Re: [Interest] Setting current QOpenGLContext with an EGLContext

It works if I add a dummy OffscreenSurface and make my context current on this before making the PBuffer current. Not sure if this is the best way of doing it though? - Thomas On Tue, Sep 29, 2015 at 11:37 AM, Thomas Sevaldrud wrote: > Hi, > > I'm still working on the

Re: [Interest] QCameraViewfinder & screen orientation changed on iOS

I'd a problem with orientation using QML VideoOutput, not exactly the same, but the autoOrientation had some bugs, i.e: Doesn't recognize the Qt .InvertedPortraitOrientation orientation. I tried to fix it, instead assigning the angle in the events: onWidthChanged onHeightChanged Maybe it can

[Interest] Strategies to create dialog boxes dynamically in Qml

Hi, I’m trying to implement a custom dialog box on qml using dynamic object creation methods. I’m using the javascript approach to create the component and then the object. The object appears on the scene and it has two buttons. The question is. What are the strategies available to receive the

[Interest] [Qt3D] Node's parent-child relationship clarification, please?

Hi, In classical scenegraph approach, the path to a node gives the relationships between the nodes. For example, the following path root -> transform -> mesh means that the mesh node will be applied the transform given by the transform node. The scenegraph's root is the parent of the transform

[Interest] Show window without 'active' or 'focus'

How do I show a window without making it 'active' or giving it 'focus'. If I understand correctly: - a widget may be 'active' in which case it is drawn differently, for example an 'active' QTextEdit has a blinking cursor. - a widget may have 'focus' in which case it is the recipient of keyboard

[Interest] Setting current QOpenGLContext with an EGLContext

Hi, I'm still working on the EGL PBuffer/DirectX integration through Qt that I posted about last week :-) Thanks to good help from this list I now have the PBuffer and DirectX texture set up with the share handle. I also have a QOpenGLContext which I have used to set up the EGL PBuffer. I don't

[Interest] QAbstractVideoSurface as viewfinder on iOS

Re: [Interest] Setting current QOpenGLContext with an EGLContext

Well, there’s no nice solution since QOffscreenSurface is backed by a window, not a pbuffer on Windows. (arguably this should be changed in some future release, for ANGLE at least, but that won’t help you now) You can make a QOpenGLContext current with a QOffscreenSurface, then call

[Interest] QJSEngine leaking memory from QObjects until eval() is complete

I'm toying with an application that uses QJSEngine to perform queries and build reports. Mostly, I was curious how well JavaScript + QObjects would be up to the job. So far, it's been going great. However, I ran into a small hurdle today. It appears that QJSEngine when garbage collecting

[Interest] Animation control and high DPI effects

Hi, guys. This may be a little rambling, so I apologize. I recently re-wrote an older, stand-alone application that was using a fairly archaic framework to use Qt5. In designing the UI, I implemented some animation support (via QPropertyAnimation) on the widgets on the interface. I found

Re: [Interest] QCameraViewfinder & screen orientation changed on iOS

Problem is still actual. I refused from QCameraViewfinder. The main problem is that QCameraViewfinder eat resourses and on UI rotation widget doesn't updates its layouts and so on. In my implementation of view finder before drawing frame I invoke QCoreApplication::processEvents(). Without it

Re: [Interest] Qt 5.5 WinRT x64 VS2013 applications fail WACK Direct3D tests

Hi Alexander, First of all, thanks for bringing this to our attention. The lack of Trim() was a regression we let in 5.5.0, although the additional D3D tests failures are caused by new items in the Windows 10 WACK. The fix is now in the 5.5.1 branch of qtbase and will be part of the 5.5.1
