@J-Hilk Thank you. Fortunately, this is a source-code library, so no DLL to worry about. There might be an equivalent function taking a memory buffer I could use, in which case I could let QFile open the file, as suggested by @Christian-Ehrlicher. Otherwise, copying the file to a non-Unicode path seems to be the only way.

@SGaist Yes I'm using c++, do you have any examples of how I can use this library for this case?

@Mihan said in Question about QThread with more than one QObject: I thought there was only one-to-one correspondence. This would be very strange, all GUI items have to be in main thread. How should that be possible if each instance would need a specific thread!

Thank you for your help. Calling lupdate form time to time is OK. I've updated repository with working code and more suitable name: https://github.com/pozemka/cmake-qt-translation-example

@sierdzio, false alarm! After reopening my project everything got built and no file existance errors were present. Your hint about adding QCoreApplication really helped!

Again: use a debugger and QT_FATAL_WARNINGS as described e.g. here to see which QPixmap triggers your error!

@Sai-Raul said in Image showing in QLabel: Already tried that And what was the outcome? Please update your code accordingly.

@kshegunov I found the problem, as you said, the local event loop is run before the global one(QMessageBox::info() is called in constructor)，but why? Where can I explain?

@Q139 Use ui->nameOfPromotedWidget

@mrjj @SGaist @jsulm Having been able to achieve some steps, can you help me here: def appendSelection(self): try: rows = {index.row() for index in self.tab.selectionModel().selectedIndexes()} lines = [] itemList = [] itemList.append(self.fname) itemList.append(self.pixpath) itemList.append(self.passlb) itemList.append(self.datetx) for row in rows: for col in range(self.tab.columnCount()): itemArray = self.tab.item(row, col) text = "" if itemArray is None else itemArray.text() if (col == 0): itemList[0].setText(text) if (col == 1): itemList[1].setText(text) if (col == 2): itemList[2].setText(text) if (col == 3): itemList[3].setText(text) Column 2 is the image column. I want to append it to a qpixmap inside a formlayout. The qpixmap in the formlayout is self.passlb. it is a QLabel. So how do I append it just like other data (text) get appended to form qLineEdits. I tried: if (col == 2): itemList[2].setPixmap() But it didn't work. Kindly help with the right line of code.

Hi and welcome to devnet, Are you sure it's Qt 4.0 ? Which version of cmake are you using ?

Hi, You have the model index, so if it's the left most one, draw the left round corners and if it's the right most one, draw the right rounded corner. The other option is to use one delegate for the first and last column to do the special painting. Note that this is not the correct solution if your users can reorder the columns.

Tricky one ! Glad you found out and thanks for sharing :-)

@JonB But that's the thing, at the end of dropEvent it seems like the drag-and-drop operators are not yet completed (things like removing rows and so on happen after we exit it). So that's going to take some unspecified time t and we must set the timer to an interval that is guaranteed to be greater than t. If we guess too low, we run the risk of running the action on an inconsistent state, so we must guess high and that may introduce a bit of a delay. Also, does timer use application-time, or wall time? If wall time, then we would not guarantee correctness because in principle the OS may interrupt the application after dropEvent exits but before drag-and-drop is over, and when we resume it the time hits and we run it on an inconsistent state. Anyway, this is all pretty academic, I think in practice your solution would work well.

@Lightshadown Because you dont have any layout, it doesn't resize properly. Assign a layout to all container where you now can see the red crossed circle. Then everything will work and resize as expected. To achieve the design you have currently, you probably need multiple cascading layouts.

@Creatorczyk Like @mrjj's question suggests only designer elements are translated (to be precise - those from UI file that qmake knows of when generates ui header file). My solution to dynamically (in code) created actions/elements is to add tr() calls to changeEvent(). Works every time.

Hi @JonB, yes, that worked perfectly. Thanks for solving this :D
