I actually have 6 QLabels, so I now have 6 timer and so on

Derive a class from QLabel and add that functionality to it. Don't write the same code 6 times!

My QLabels have the sizePolicy horizontal: preferred and vertical: fixed and a vertical length of 20.
When a text is displayed, the QLabel expands so that the elements above the QLabel are also moved upwards and after the text disappears, they go back to their initial place.

Fixed size policy means that widget uses its sizeHint() as the size. If you change the text the size hint also changes, so label grows/shrinks.

PATH ? Why did you change that environment variable manually ?

@Bonnie It works! Thank you Sir or Madame!

The question is very general. So what exactly is the problem you cannot solve, and what have you coded so far?

Hi,

To add a layout to a layout there's the "addLayout" method.

Hi,

How did you set the QLabel on your QScrollArea ?

If you put it in a layout on the scroll area then that's wrong.

Rather than giving the pointer to your MainWindow instance, pass directly the pointer to your label. Basically:

mainwindow->ui->label

Thanks for the support guys. I tried making a transparent QPixmap image using Qt::transparent fill for the axis and overlaying it onto my other QPixmap, however it didn't work properly. So I ended up just drawing directly onto the image itself. Not the most efficient method but it seems to work...

@rjmoses
Yes it will scale all images to match IconSize.

An update on this. It works perfectly and its a very low-cost solution. My processing time remains almost the same (~10mS) using this method since the painter does the scaling for you when it draws.

Thanks for your help guys.

@SGaist said in Add Qlabel as item in QTableview:

QStyledItemDelegate

Ok..I'll try with that.
from google search maybe this kind of output it will give, which maybe as our requirement.

Else, I have some lengthy approach..implement custom label with mousepressevent handled which emits the object name and add these custom labels, 20 in HLayout and add hlayouts in a vlayout...

Thanks!

@SGaist Thank you very much for the quick reply.

I've removed both the horizontal and vertical layout boxes and everything works exactly as I want.

Sometimes newbies make life more complicated for themselves than it needs to be!

Thanks again!

no, decrese the font size and see if it works. then you'll know whether you can change font size at all. If it works then that should be a hint as to why you cannot increase the size.

@mrjj I tried your code, here's the result:
0_1549363016752_5cd8c55d-9905-4b92-bb0b-126715f37cae-image.png

I resolve it.

I setted font of text as property of QML Text component.
(Like font.family : parent.fontfamily)

and on Qt 5.7's QML, there are no enough options to control font properties.

so, I moved to C++ side and set a whole application font.

QFont font = someClass.getLangFont();
//set property of font instance here
// such as hinting policy, style etc.
QApplication::setFont(font);

now it looks very cleary...

thank you..

Why are they not ?

The Basic Drawing Example shows that. In your case, you'd likely just have to paint your image using the correct scaling information.

@SGaist got it.

Thanks for your answer, unfortunately this part of my code is executed in a class that inherits from QMainWindow, I don't have access to the QApplication.

Edit:

It works using QCoreApplication::processEvents() instead.
