    You can use it the same way it's done for the Qt libraries in your cmake file.

    @Aman55 Yes, you need to look at the stack trace pane in the debugger when that happens, so that you know where it comes from.

    Hi Slandino, I started working a few days ago on a project to mix Qt and flutter. I have already some working code, but it's using offscreen buffers (my final objective is to make a plugin to have a flutter layer in OBS) so I've not even looked on how to render to a window context. But the code may still work for you. I've commited the mess of code I wrote so far to https://github.com/hefsoftware/temp_qt_flutter (it compiles on windows, at least for me). Hope it will give you some help.

    @JonB Hi these I have already included.
    Also, I have seen a few examples at Github. I have tried to compile with MSVC as well as MinGW.
    These are the errors:

    moc_india_map_test.obj:-1: error: LNK2001: unresolved external symbol "public: static struct QMetaObject const QgsVectorLayer::staticMetaObject" (?staticMetaObject@QgsVectorLayer@@2UQMetaObject@@B) moc_india_map_test.obj:-1: error: LNK2001: unresolved external symbol "public: static struct QMetaObject const QgsRasterLayer::staticMetaObject" (?staticMetaObject@QgsRasterLayer@@2UQMetaObject@@B)

    after I try to run the project.

    Same issue, I have also got this cmake warning:

    -- qmlplugindump failed for org.kde.quickcharts. -- Could NOT find org.kde.quickcharts-QMLModule (missing: org.kde.quickcharts-QMLModule_FOUND) The qml plugin 'QuickChartsplugin' is a dependency of 'project', but the link target it defines (KF6::QuickChartsplugin) does not exist in the current scope. The plugin will not be linked.

    @3n3l said in TUIO multi-touch:

    Got it working, the issue was that my sending application would be in focus and then my qml application would not receive touch events when being out of focus (What?).

    I've been bitten by that issue category. Using a virtual machine that won't know it has lost focus from the physical input hardware is another solution, although not as convenient as the environment variable.

    One of the examples provided by qcustomplot is a plot of a cos wave (https://www.qcustomplot.com/index.php/tutorials/basicplotting) I'm sure you can adapt it for your needs

    I considered bypassing Epics with Qt Charts/Graphs because of EPICS's limited support. CLosing the thread.

    I managed to fix the issue. The flatpak version only draws StyledPanal frame shadows when the parent widget is using a grid layout where at least one of the spacing values (horizontal or vertical) is not 0. Any other layout (VBox, HBox, Splitter or Dialog ) and the frame shadows are not drawn. So the fix in my case was to place each of my QTableViews inside of an otherwise empty QWidget that uses a grid layout with any non 0 spacing (negative values work as well).

    Since when has Firefox something to do with Qt?

    I don't think this is directly possible. You could try to use QWidget::createWindowContainer to start a browser and capture its full window. Some smart event filtering could then resize and move the captured window together with your own main window.

    Hey, that sounds awsome! Could you explain which files you edited or even share your files for Qt 5.15.2 ?
    Sorry, I´m just a user of 3D Software and would really enjoy working with the spacemouse in my Qt apps.
