QML and Qt Quick

It's okay, it fixed itself ! The move to Qt6.8 has taken QtGraphs out of Technology Preview status, and functions like append(x,y) that weren't accessible in QML now are.

I found a simpler way to do it, see the following: import pathlib import sys from PyQt5.QtGui import QFont, QFontMetrics, QColor from PyQt5.QtWidgets import QApplication from PyQt5.Qsci import QsciScintilla, QsciLexerPython class SimplePythonEditor(QsciScintilla): def __init__(self, parent=None): super().__init__(parent) # Set the default font font = QFont() font.setFamily("Courier") font.setFixedPitch(True) font.setPointSize(10) self.setFont(font) # Margin 0 is used for line numbers fontmetrics = QFontMetrics(font) self.setMarginsFont(font) self.setMarginWidth(0, fontmetrics.width("00000") + 6) self.setMarginLineNumbers(0, True) self.setMarginsBackgroundColor(QColor("#cccccc")) lexer = QsciLexerPython() lexer.setDefaultFont(font) self.setLexer(lexer) if __name__ == "__main__": app = QApplication(sys.argv) editor = SimplePythonEditor() editor.show() editor.setText(pathlib.Path(sys.argv[0]).read_text()) sys.exit(app.exec())

@JLouis56 Not 100% sure what you are saying, but the The Qt Resource System allows you to embed resources like JPG files inside your executable. Then there is nothing to store externally, when you run the program outside Creator or release it to someone else the images are accessed by your application inside itself.

Which Qt Version are you using?

I understand. From now on, we will not add photos and will display it as text. Thanks for your reply.

@flaudio I could do that, but I greatly want to keep that second parameter a QVariant. This function is eventually going to be used for a variety of purposes, and I'll need to convert that argument to several different things.

Hi @KeshavJ, I don't think that there are other ways to use animation in canvas. Using canvas you can handle pixel by pixel movement using a Timer (very ugly alternative). Instead of using canvas, have you tried a Shape component? It could be a valid alternative. Advantages: use declarative programming (real qml power) and higher performance (test with a qml profiler). Disadvantages: less flexible (i.e. fixed number of points to draw).

In some Qt Quick Controls styles the icon are rendered in monochrome. Linux has a different default style than window.

Yea exactly @Lord_Naikon thank you for your support I just made two uniform buf with same set of data as mentioned now its working. Thank you soo much

could u add the example code for this

MinGW perfectly works now !!!! If anyone moving MSVC->MinGW you should check project cmake's "Current Configuration". which would be set to C:/Qt/5.15.2/msvc2019_64/ ~~~. It must be changed to C:/Qt/5.15.2/mingw81_64/~~~ And in QML file, Map field should have "achors.fill: parent" All fixed well. super thanks to @SGaist you saved my life

Thanks for all the help, guys. I was able to get this working like so: GridView { required property Space space property var spaceFeatureList: sceneModel.featureUuidList(false, space.uuid) ListModel { id: spaceFeatureListModel } Component.onCompleted: { spaceFeatureListModel.clear() for (var i = 0; i < spaceFeatureList.length; i++) { spaceFeatureListModel.append({ "uuid": spaceFeatureList[i] }) } } model: spaceFeatureListModel Connections { target: sceneSetupPane function onFeatureListChanged(spaceId, activityId, status) { if (spaceId.localeCompare(space.uuid) === 0) { if (status) { var i for (i = 0; i < spaceFeatureListModel.count; i++) { if (spaceFeatureListModel.get(i).uuid === activityId) { break } } if (i >= spaceFeatureListModel.count) { spaceFeatureListModel.append({ "uuid": activityId }) } } else { for (i = 0; i < spaceFeatureListModel.count; i++) { if (spaceFeatureListModel.get(i).uuid === activityId) { spaceFeatureListModel.remove(i) break } } } } } } The function could probably use some optimizing, but it works. Thanks again.

IIRC, the app version and driver version might not be linked. As for Qt Graph, AFAIK, the goal is for it to replace Qt Charts in an improved way but I haven't had the occasion to use it yet so I am sorry I can't be of more use on that front.

the question is resolved - you can delete it, the problem is that for some reason the model 3d inside Node does not respond to clicks. I will find out why.

I prefer less logic in when I call a function, and more logic where the function simply exits when some parameters are still missing, but that's a...philosophical difference.

Hi, I think that's a question better asked directly to the GammaRay authors

I don't know whats happened. But after trying today, the problem perished. Maybe an sdk update did it. Don't hope it will get back. Problem solved for now.
