General and Desktop

One possible way would be to have a QThread and use the worker object approach.

Hi, Follow the guide lines shown in Creating Shared Libraries with regards to the macros.

Hi everyone, Little update of my progress: Using a persistent editor seems to be the best solution from my point of view It is completly transparent from the creation in paint() (calling openPersistentEditor -> createEditor) to its destruction (calling closePersistentEditor provoking a re-opening and a redraw of the editor) The editor, a custom widget, responds correctly after handling setModelData, updateEditorGeometry and editorEvent I'm still not sure that is the good way to proceed but it works fine. I'm closing the subject. Thanks for your reading.

Hi, Before anything else read here why adding this moveToThread call is the wrong thing to do.

I solved! the problem was of the macro: #ifdef _DEBUG #define new DEBUG_NEW #endif this macro only works if compiled under the Visual Studio development environment in DEBUG mode. just change the macro in: #ifdef QT_DEBUG #endif and add in .pro file: CONFIG(debug, release|debug):DEFINES += QT_DEBUG and Hola works with this macro under the Qt Creator development environment in DEBUG mode

@mrjj I don't want to resize it via a dialog. I need to do that with the mouse (manually)

@JonB , @jsulm , @VRonin thanks QString dd ="2018-08-01"; qDebug() << "ddddd" << dd; QDate da=QDate::fromString(dd,"yyyy-MM-dd"); QString dw = da.toString("dd-MM-yyyy"); well this is solved like this :D

@mrjj I tried your code, here's the result: [image: 0a2df4f3-38c9-4f54-affe-c60ba74d14c0.png]

@SnuggleKat No problem, happens sometimes :-)

@SGaist thanks

Hi, We can't see your images. By the way: What version of Qt ? What OS ? What compiler ? What graphics card ?

I'm throwing darts at the wall to see what sticks -- since the video is not showing correctly I've tried all sorts of combinations of showing the various individual components. Right now, the only thing that works is if I create a QCameraImageCapture, attach it to the camera, and after a couple of seconds call setEncodingSettings on it, that seems to trigger the videoItem to show the image. Interestingly, even if no image is showing, that imageCapture object correctly pulls the data off of the webcam and stores it to a file.

Thanks for the analysis ! Would it be possible for you to provide a minimal project with the two corresponding Xcode projects ? If not already there, would you open a feature request on the bug report system with it ?

You're welcome ! If you have all the answers you need, please mark the thread as solved using the "Topic Tools" button so that other forum users may know it's good :)

Hi @UnitScan, so please mark this topic as SOLVED too. Thanks!

Can we finally see where and how you emit dataChanged()? And with which indexes?

I didn't figure out why deleteChar() didn't do its job but I managed to find a workaround: if e.key() == 16777235: try: if self.tracker != 0: cursor.select(QTextCursor.BlockUnderCursor) cursor.removeSelectedText() self.appendPlainText(self.name) self.insertPlainText(self.commands[self.tracker]) self.tracker += 1 except IndexError: self.tracker = 0 return Basically I am removing the block and adding the necessary stuff back to it along with the last used command. Here's a little demo on what I'm working on: https://raw.githubusercontent.com/Fuchsiaff/Content/master/Peek 2019-02-04 21-06.mp4
