how to automatic press a key in Qt5.///

mrjj

Hi
Its a little vague what you want to do :)

You mean press a key in your own app for some other app ?

i just want to automatic reload and display infomation to a widget by Key_F5 but not touch F5 .

@Duy-Khang
well you can try sending it a key event (up and down events)

QKeyEvent * eve1 = new QKeyEvent (QEvent::KeyPress,Qt::Key_F5,Qt::NoModifier,"F5");
QKeyEvent * eve2 = new QKeyEvent (QEvent::KeyRelease,Qt::Key_F5,Qt::NoModifier,"F5");

qApp->postEvent((QObject*)ui->thewidget,(QEvent *)eve1);
qApp->postEvent((QObject*)ui->thewidget,(QEvent *)eve2);

Does F5 normally call your own code or is it a widget HTML browser and it is its code ?

in picture 1, i will change information and after picture 1 closed, I want picture 2 automatic update information. How I o=do it ?

Hi,

Looks like picture 2 is a dialog, so if you are using exec, just update the content of picture 1 and it will be refreshed automatically.

Other than that, you should provide more information about what is picture 1.

@Duy-Khang It all depends on how the picture-2 data is populated?
if this information is through database of student? then ,
in picture-1 you are having "Update" button right? Store the updated information into database first and reload the picture-2 to reflect that data is updated.
