@JonB Sure thanks for your words

@rajendrasp79 said in How to build and run simple qt application: it is working fine. so please mark your issue as solved then, thanks.

@chris_rookie One possibility might be to follow the pattern in https://stackoverflow.com/questions/17221621/how-to-set-qt-tooltip-width. A more complex discussion is in https://stackoverflow.com/questions/4795757/is-there-a-better-way-to-wordwrap-text-in-qtooltip-than-just-using-regexp.

@mrjj thank you.please give me a reputation

So you have to override the flag() method to fix that

Two years too late, but as I was having the exact same issue it might help a lost soul in the future. A workaround for this is to save a temporary image and copy to clipboard the url to the file. This is recognized in most software on Mac (PPTX, Keynote included) and should work on Windows. void ToClipboard(const QPixmap& pixmap) { QString filename = "/tmp/screenshot.png"; pixmap.save(filename); QList<QUrl> urls; urls << QUrl(filename); QMimeData* outputMime = new QMimeData; outputMime->setUrls(urls); qApp->clipboard()->setMimeData(outputMime); } Take care of the typical caveats when writing to disk from an application, but for most applications that might need this (user-generated, user-controlled operations) this is an ok workaround.

Yes it Run Thanks a Lot ..

@mrjj Great now its reaaly works , Thanks a lot HAve Fun .. :-) MArked as solved

@jsulm said in Clearing QLineEdit leads to segmentation fault and crash: @Shoaib-Muhammad Member variables are variables defined in a class, like: class A { private: int aVar; // aVar is a member of class A }; Local variables are variables defined in a local scope. Local scope can be inside function or method for example: class A { private: int aVar; // aVar is a member of class A void someMethod() { int aVar = 0; // This is a local variable which only exists inside someMethod and is NOT the same as aVar above! // aVar = 0; //If you do it like this then you access the member variable } }; The problem with your code is exactly this: you define local variables with exactly same names as your member variables. Thank you for the concise and clear explanation. It does make sense now that you mention it.

@SGaist Thanks.

Hi, If you want to use your application outside Qt Creator, you have to follow the deployment instructions. The most simple is to use windeployqt for that.

Hi, The visualRect method comes to mind for that.

Is there no way to initiate styleDelegate with pressed flag maybe? Regards Dariusz

@Chris-Kawa Dear Chris, thx again. this solved a lot. I have incorporated your recommendations. Now the image gets "cropped". You may tell me again what's wrong or why this happens. thx again in advance. The actual test: http://files.lacunasolutions.com/various/ImageViewerBogo-mod3.zip

@J-Hilk thanks for your feedback

Finally found the solution. I modified the udp buffer to a very large value as mentioned here... http://thewowza.guru/how-to-increase-udp-buffers-under-windows-os/ using setsocketoption to about 1250000 and voila! it works with out any packet drops. Finally relieved :)...

@dheerendra thank you for your quick answer. But I want to block ONLY the vertical and horizontal resize, but I want TO ENABLE just the window corner resize, like a proportional image resize keeping the window aspect ratio. option 1: blocks all option 2: blocks all option 3: I have the MainWindow::resizeEvent(QResizeEvent *event) method, but I don't know how to filter this specific window corner resize event. Could you help me?

@SamurayH Thank you so much! I'm looking for this line for hours in the Qt documentation...
