[Interest] Questions regarding Scene Graph (QSGClipNode, QSGTexture, QSGOpacityNode)

1. Could you tell me please how one can set custom geometry for QSGClipNode (not the rectangular one)? Should I just create QSGeometry with QSGGeometry::defaultAttributes_Point2D() attribute and add vertices? Will Scene Graph recognize that polygon is closed (I need clipping to have a form of

[Interest] QStateMachine as C++ (or Python) backbone of QML app

Hi all, Back in 2010 there were a couple of interesting threads on this list regarding the use of state machines: http://comments.gmane.org/gmane.comp.lib.qt.general/29861 http://comments.gmane.org/gmane.comp.lib.qt.general/36760 In the second one, which was about using a C++

[Interest] .pc file generation

Hi, Re: https://codereview.qt-project.org/#/c/140954/ Is the justification for omitting .pc files still relevant that "frameworks are currently broken anyway"? They don't appear to be, but omitting pkg-config files for them makes it impossible to build all dependent software that uses

[Interest] QPushButton shortcut works on Qt 4 but not 5

Hi all, Maybe I'm doing something completely wrong, but on Qt 4.8.7, this works (pressing Ctrl+O prints "clicked"): test.cpp: #include #include #include #include #include class MainWindow : public QMainWindow { Q_OBJECT public: MainWindow(QWidget *parent = 0) :

Ok I solved an other problem. So, if somebody has the same problem: Use add_library($PROJECT_NAME} SHARED...) instead of add_executable($PROJECT_NAME} SHARED...) since on the android it is only a shared library and not an executable. > Am 06.05.2016 um 17:56 schrieb NoRulez

Re: [Interest] qt.labs.controls / QtQuickControls2: ToolBar, Label / Image Colors, tinting...

To make it work with black images the formule should be that : gl_FragColor = (tex + color) * qt_Opacity; But your color must have alpha at 0 else you'll loose the alpha of the texture. Here is the bug of graphical rendering issue when using graphical effects :

Re: [Interest] qt.labs.controls / QtQuickControls2: ToolBar, Label / Image Colors, tinting...

Your image is black because the shader is multiplying the color. You should do your image sources in white to get the correct result. You can also change the operation in the line : gl_FragColor = tex * color * qt_Opacity; As I know if you are using a GraphicalEffect by image you'll have the

Hi all, In a fullscreen page-based embedded QML app (HMI), I find myself often wanting to disable all signal connections when the page is not active (on top of stack). I found this 5 year old bug: https://bugreports.qt.io/browse/QTBUG-18245 I think Daniel's analysis in the comments is very

PS. I just realized you're worried that the functions are virtual. Well this is of no consequence, the vtable is respected (if I remember correctly that's specified in the standard). So the following should also be working without any problem: QObject::connect(a, Interface::someSignal, b,

@ Xavier: the ToolButton Image still is black, but perhaps I did something wrong. It's the first time I used a ShaderEffect Do you really think it could cause problems on Android / iOS apps ? Images are small images @ J-P: ColorOverlay works well and also looks easier to understand for mobile

Re: [Interest] Are slots even needed these days?

Nobody's mentioned that Qt4-style connect syntax is required to solve the diamond inheritance problem that frequently appears when using a signals/slots interface. Ex: class Interface { public: virtual QObject* asQObject()=0; protected: //signals virtual void someSignal()=0; public:
