3rd Party Software

@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.

@gfxx so try to leave out folder open62541 and use only generated libopen62541.so .....

these step for qropcua:

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).

@Stuarte said in Problem connecting to web:

the web using Firefox 115.12.0esr (64-bit).

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.

You have to compile the library as static lib.

Hello, @orsini29 I am encountering the same issue and I am lost as well. I have read everything that has been suggested but I am still not sure how to concretely implement stmp into my project. Could you be more specific on how you have manage to do it please ? It would be a great help to me, thanks :)

@trin94 Thanks for getting back to me and for all your help

@mtrch
Agree with you, I say because I did practice what you mentioned here.
Yes, it is workable.
Best regards,
Thuan T. Nguyen

Ok finally builded, thanks for help :)

@hzha said in disposition qxmpp:

didn't work

In what way it didn't work?
Saying "didn't work" does not help much.

Please show your CMakeLists.txt. You are not linking against the Qt library.

@Christian-Ehrlicher

If you look at qwt oscilloscope example the curve data is updated in another thread than GUI.
I do the same. I update only the curve data and guard it with mutexes. In replot the data is locked. But I guess this must be the reason so I'll try to come up with a small compilable example to show the error.

@mtalha2621 My bad, I misread the error messages. What I had in mind when answering is for you to use your custom pipeline with OpenCV.

@Christian-Ehrlicher

Yeah, this seemed to be the problem...
Took much longer to than I want to admit before I found it...

I wanted to post my fix already, but newbies on the forum can only post every 10 minutes 😅
