General and Desktop

Hi, Yes it does. It's called automatically when you load a new translator. If you want to implement something similar for a non Designer based widget, see the Prepare for language changes chapter in Qt's documentation.

@BushyAxis793 one last thing: making your root account available on any and all point of access of your MySQL server is a wrong idea. You should rather create a dedicated user that has access to a specific database for that purpose.

@JonB Thank you, what you said helped me find what I was doing wrong : I did set the GraphicsView's sceneRect width and length properties. Setting them to 0 make it work as I needed. The screenshots are what I had as view, on the first one the scale as 100% and there are GraphicsItems to the left but no scrollbars. The second screenshot is at scale 30%.

@Raul200000000009 said in Can not read from QTableWidget: Any ideas? Take a look into the QString documentation would be a good start.

@Perdrix Code is fine. Not sure what your question is. If you identify the row by comparing the text of one column against what you are looking for that's OK. Then you set each column's item to some text that's OK. If, for example, there were other magical calls, such as "set a whole row of columns to this list of values" then it would be documented, but it isn't.

@Abderrahmene_Rayene Thank you! The problem solved. Have a nice day!

@JonB It looks like the crash is gone, thanks for the help.

@nslw Then replace -Wno-inconsistent-missing-override with -Wno-suggest-override in the settings I mentioned.

@Mesrine I guess understand. I will access the QML side in the form of a direct directory in the form of array[0]. thanks for helping.

@Xav12358 So you have it working now, right? I have no idea about the QtCore.SIGNAL("...") syntax you are trying to employ, never used it and would not use it. I tried with your original syntax involving self.emit(SIGNAL("item_signal(str, QImage)"), "hello", QImage()) and got the same error as you about str needing to be registered. Threw that away and replaced with "proper"/"normal" syntax: self.item_signal.connect(self.new_image_callback) ... self.item_signal.emit("hello", QImage()) and all is well.

@Paul-Colby It is unfortunate that a global data index is not available, as that would have solved the issue that I was having. I went ahead and implemented the third option. I may revisit how I am loading the files in the future to rewrite the test_data functions to only include the data that I need.

@Christian-Ehrlicher Thats a good point. Thanks! Using the same definition for both libraries if not included correctly the headers could define the export on the symbol that should have an import statement. This is not completely clear to me so Let me try. I let you know :). Yes, that was the problem. Many thanks.

@JoeCFD Yes, that was the problem Adding the proposed code fixed the problem.

@zhaiyg I guess qwt is made mainly for 2D. VTK has much more for 3D rendering.

ok, I know how to do this but its really really ugly. It essentially is 2 sets of 10 calls to invoke in my sourcecode and some logic to decide which of the invoke() methods I actually call. I have 10 calls based on the amount of arguments there are. So, Qt is awesome it deprecated the methods only to force me to write 10 of them.. Then the invoke returns false if you pass in a default-constructed QMetaMethodReturnArgument which indicates 'void'. No, you have to call it without that argument if the method returns void. So... Yeah, another set of 10 calls.. I'm hoping I missed something, because this is beneath Qt

@TomZ Thank you, I follow the order you mentioned and it works fine. if (doSVG) { painter.setFont(fNum); painter.setPen(pNum); painter.save(); painter.translate(c.toPointF()+ b.toPointF() +tit->pos()); painter.rotate(radToDeg(ra)); painter.drawText(- ti->boundingRect().width()/2, -2, QString::number(n)); painter.restore(); } [image: f90e196d-9f24-4761-b97f-8be48db48754.png]
