@borasemiz I have solved it. I discovered that I needed to refresh my plot, which is to say I needed to re-plot my plot. Let me: //I am just skipping to the click function of my button QCPItemStraightLine* line = (QCPItemStraightLine) (ui->widget->item()); line->point1->setCoords(5,6); line->point2->setCoords(5,7); ui->widget->replot(); //This line solved the problem.

Hi and welcome to devnet, When using stylesheets a special QStyle is used to render your styled widget. Since you are only modifying the background, changing the QPalette of your QTableWidget might be enough. Hope it helps

Hi and welcome to devnet, The latest state of SVG support is described here AFAIK if you need a full blown SVG renderer then you'd need e.g. QtWebKit

Hi and welcome to devnet, What about painting a partially transparent rectangle over the part of the text that should be highlighted ? You could draw the text first and then the rectangle over. Hope it helps

Hi, The only good answer is: benchmark. In any case, Qt's State Machine Framework is not know to be slow so unless you're expecting speed of light it should run well enough.

Cocoa VS Carbon was another situation, you would either build for one or the other, you wouldn't have both at the same time. In your current situation, how do you plan to distribute the wayland version of your application ?

Those plugins can be tricky… Happy coding !

@SGaist Ok, I just tried to rescaled my image array within an intensity between 0 to 255 and cast a uchar*, it's working now. Thanks

Qt provides Q_DECL_OVERRIDE which extends to the override keyword if C++11 is used and to nothing otherwise

if you call map[n] it will create an element if it's not contained. use map.value(n) instead. If you don't care about iterators becoming invalid after the removal use QMap::remove(). otherwise use itr = map.find(i); if(iter!=map.end()) map.erase(itr);

Yes, it's possible. For VC++ you can use Wix that integrates with Visual Studio. But you can take a look to use the Qt Installer Framework

@vinod Hi, this is the wrong solution. If you want to call your application from the explorer you should follow the same steps as if you would deploy your application on another machine. Modifying your PATH environment variable like that means that any application installed using Qt dynamically will now use the one you have in C:\Qt\Qt5.4.1\5.4\mingw491_32\bin which is not something you want.

I found solution. i remplemented keyPressEvent from QTextEdit class void MyTextEdit::keyPressEvent(QKeyEvent *e) { if(e->key() == 16777220){ //enter clicked return; } return QTextEdit::keyPressEvent(e); }

I use qml to make it work.WorkerScript
