Hi and welcome to devnet,

Did you build Qt yourself ?
Can you provide a minimal compilable example that shows this behavior ?

@lorenwell said in Howto dynamically modify 2D array of QvariantList?:

What I am doing wrong?

You forgot to add/replace list2 in list1 after you modified it.

UPDATE
I have narrowed it down to TAB widget....

@JonB said in How to get the text output from an ui program with the qprocess:

NOTE: Whether what you call "an ui program" will actually write anything at all to stdout/err is a different matter.

I assumed that project "a" (the one running as QProcess) is @nicker-player 's own additional Qt GUI app :)

//project a: int main(){ qDebug()<<"output"; }

One more thing, the issue is hard to reproduced.
Only one time found in our linux terminal.

@Christian-Ehrlicher Thanks dude, after trying the same code with Qt 6.6.3 the connection works. So we just need to wait for a patch for this problem. Dang, I thought there was an error in my code or my setup.

@Shubham_Senpai
Please edit your post and use the code tags to format the code you post.
Makes it much easier to read and reply :-)

@sierdzio
Simple minds not only think alike, but also post at the same time :-)
But I must admit, knowing color hex codes by heart exceeds my level!

@Luganda01
I have succeeded in pushing the translations to the dev branch.
What to do about the 5.15 branches remains to be seen.

Regards,

Kizito

I still fail to understand what you're doing. What do you mean by "installed qt-everywhere-src-5.15.13" - do you mean you built Qt by yourself?

You alse seem to built Qt statically (@ChrisW67 pointed out that already) - is that what you want?

Well, it was the newAVIImage slot the instigator of this error. It used glTexImade2D for all frames images. You should instead use glTexImage2d for the first frame, then use glTexSubImage2D for the subsequent frames. It seems like a memory problem that takes a while to reset.

@Hamza-Umair said in How should I use the model/view for my application:

@jeremy_k I can not use an item view becuase the items are different? In my understanding of qt item model/view, you can not do that. I am probably wrong though.

You absolutely can have different types of data in a single view. Use a designated role in a designated column to indicate the type. A view delegate can use this role to alter the display for each type.
QStandardItem::type() is another way to represent this strategy.

A view can also use a filter model to remove types that should be hidden. QAbstractItemView::setRootIndex() can be useful for limiting display to children of a particular node (i.e. the Bond list of a particular Molecule)

The address book demonstrates filtering and multiple views from a single model.

@Sevi hi,

What you did is pass the Qt qml sources, so windeployqt will copy absolutely everything.

The qml parameter should point to your project's qml files so only what is required is copied.

@AnneRanch said in change central widget size ?:

Can I change / set heigh of the central widget to occupy only part if the QMainWindow display area ?

No.

void MyGLWidget::newAVIImage(QImage image) { static int ss =0; image = image.mirrored(); // bindTexture(image); glBindTexture(GL_TEXTURE_2D, m_tex); image = image.convertToFormat(QImage::Format_RGB888); if (ss==0) { glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, image.width(), image.height(), 0, GL_RGB, GL_UNSIGNED_BYTE, image.bits()); ss=1; } else { glTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0, image.width(), image.height(), GL_RGB, GL_UNSIGNED_BYTE, image.bits()); } update(); }

The above code solved the problem, that is using glTexImage2D for all frames was the culprit, it should be used only for the first frame. Subseqent frames should use glTexSubImage2D.

@jdent
You have to iterate through the rows looking for the value you want.
If you use a QSortFilterProxyModel you can take advantage of binary search for speed if you sort by primary key. QSqlRelationalTableModel is not important here, all that gives is a "lookup" on one field to map e.g. an integer value to a corresponding string from a related table for display.

@Christian-Ehrlicher Thanks for the assistance. I managed to build and install it. Found the dylib and manually pasted it into ../macos/plugins/sqldrivers and in the build directory of my program but my program says that it still can not find the driver. I will provide some screenshots. If you notice anything wrong please let me know.
Sorry for the link but they are too large apparently https://imgur.com/a/qPy7eko

I tried to debug further but some things i get are just strange. I can't figure out why this happens:

ORIG TOP LEFT 0 ORIG BOTTOM RIGHT QPointF(450,292) ORIG TOP LEFT 0 ORIG BOTTOM RIGHT QPointF(450,292) ORIG TOP LEFT 0 ORIG BOTTOM RIGHT QPointF(450,250) ORIG TOP LEFT nan ORIG BOTTOM RIGHT QPointF(450,250) ORIG TOP LEFT nan ORIG BOTTOM RIGHT QPointF(450,250) ORIG TOP LEFT nan ORIG BOTTOM RIGHT QPointF(450,250) ORIG TOP LEFT nan ORIG BOTTOM RIGHT QPointF(450,250) ORIG TOP LEFT nan ORIG BOTTOM RIGHT QPointF(450,250)

Here is the code i get the debbug from:

#include "handleitem.h" #include "resizablehandlerect.h" #include <QGraphicsSceneMouseEvent> #include <QDebug> #include "resizablepixmapitem.h" HandleItem::HandleItem(Position position) : handlePosition(position) { setFlag(QGraphicsItem::ItemIsMovable); } void HandleItem::mousePressEvent(QGraphicsSceneMouseEvent *event) { ResizableHandleRect *rectItem = dynamic_cast<ResizableHandleRect *>(parentItem()); if (!rectItem) { return; // Wenn das Parent-Item kein ResizableHandleRect ist, beende die Funktion } QRectF boundingFrameRect = rectItem->selectorFrameBounds(); OriginTopLeft = mapToScene(boundingFrameRect.topLeft()); OriginBottomRight = mapToScene(boundingFrameRect.bottomRight()); QRectF SceneBoundingFrameRect(OriginTopLeft, OriginBottomRight); qDebug() << "ORIG TOP LEFT" << OriginLeftCenter << "ORIG BOTTOM RIGHT" << OriginBottomRight; OriginBottomCenter = SceneBoundingFrameRect.bottom(); OriginTopCenter = SceneBoundingFrameRect.top(); BottomCenterWasDragged = false; TopCenterWasDragged = false; } void HandleItem::mouseMoveEvent(QGraphicsSceneMouseEvent *event) { ResizableHandleRect *rectItem = dynamic_cast<ResizableHandleRect *>(parentItem()); if (!rectItem) { return; // Wenn das Parent-Item kein ResizableHandleRect ist, beende die Funktion } QRectF boundingFrameRect = rectItem->selectorFrameBounds(); QPointF topLeft = mapToScene(boundingFrameRect.topLeft()); QPointF bottomRight = mapToScene(boundingFrameRect.bottomRight()); QRectF SceneBoundingFrameRect(topLeft, bottomRight); //qDebug() << "HandlePosition: " << handlePosition; switch (handlePosition) { case TopLeft: break; case TopCenter: SceneBoundingFrameRect.setTop(event->scenePos().y()); if(SceneBoundingFrameRect.bottom() < SceneBoundingFrameRect.top() && BottomCenterWasDragged == false){ qDebug() << "-- (2)SWITCH Top to Bottom"; handlePosition = BottomCenter; TopCenterWasDragged = true; } break; case TopRight: break; case RightCenter: break; case BottomRight: break; case BottomCenter: SceneBoundingFrameRect.setBottom(event->scenePos().y()); if(SceneBoundingFrameRect.bottom() < SceneBoundingFrameRect.top() && TopCenterWasDragged == false){ qDebug() << "(1)SWITCH Bottom to Top--"; handlePosition = TopCenter; BottomCenterWasDragged = true; } break; case BottomLeft: break; case LeftCenter: break; default: break; } if(SceneBoundingFrameRect.topLeft() != OriginTopLeft && BottomCenterWasDragged == true){ SceneBoundingFrameRect.setTopLeft(OriginTopLeft); BottomCenterWasDragged = false; qDebug() << "(1*)Correct Top, Bottom was Dragged!" << SceneBoundingFrameRect.topLeft(); } if(SceneBoundingFrameRect.bottomRight() != OriginBottomRight && TopCenterWasDragged == true){ SceneBoundingFrameRect.setBottomRight(OriginBottomRight); TopCenterWasDragged = false; qDebug() << "(2*)Correct Bottom, Top was Dragged!" << SceneBoundingFrameRect.bottomRight(); } QPointF topLeft2 = mapFromScene(SceneBoundingFrameRect.topLeft()); QPointF bottomRight2 = mapFromScene(SceneBoundingFrameRect.bottomRight()); QRectF NEWBoundingFrameRect2(topLeft2, bottomRight2); rectItem->setSelectorFrameBounds(NEWBoundingFrameRect2);

If you want only a single instance of your application running you should take a look at QtSingleApplication

That’s a known bug. Working on it…..
