[SOLVED] Getting size of viewable aread of QTextEdit

voidtrance

Hi all,

I'd like to get the size of the viewable area of QTextWidget. What I mean by "viewable area" is the window in which the user can see the document content. This viewable area does not include the scrollbars (if they are shown), just the content windows.

The layout of the application is such that I have a QTabWidget which contains the QTextEditor widget. So what I would expect to happen is that if I do the following sequence:

Open a new tab
Resize application window
Open a new tab

the tabs opened at step 1 and 3 would show a difference size. However, they don't. The sizes returned by QWidget.size() on both the editor widgets are the same.

I don't understand how that could be. Any help?

voidtrance

Any ideas on how I can get the size I am looking for?

Have a look at QTextDocument::size()
You get from the document() function.

This is just guessing. Did not code test it :)

I am not exactly sure what QTextDocument::size() returns but it is not the size of the visible area of the document. In fact, if I follow the same procedure as in the original post, the size printed return by QTextDocument::size() is exactly the same regardless of the fact that the visible area has been shrunk to about 25%.

And you have set a layout so that the editor auto adjust to the size of the tab widget and the form
also has a layout that makes the tabwidget auto adjust to the size of the form?

I must be doing something wrong here as
ui->textEdit->size().width();

Does report different sizes when i resize the form.

sorry for not understanding.

I am a little confused about your question regarding layouts but as far as I know everything is setup correctly.

The QTextEdit widget in question is embedded in several layers of other widgets but they all have their layouts set correctly. The QTextEdit widget properly changes when I am resize the main window. Also, the scrollbars properly resize themselves to represent the chunk of visible content when I resize the main window.

All of that leads me to believe that I have them embedded properly. However, QTextEdit->size() still returns the same size regardless. Therefore, I am thinking that I am doing something wrong. I'll investigate further.

Ok. what Im asking is if you setup the layouts but from your answer,
it seems you have them setup and working as
expected.

My mini test must be wrong in some regards as Size() before and after resize mainwindow does
give changed values.

If you make a mini sample using the forms editor and just placing a tabwidget
and give it 2 tabs with TextEdits, does size() then give you expected values?

voidtrance

OK, well, I feel dumb!

The reason why the size printed every time was the same is because I was printing the size prior to the QTextEdit widget receiving its initial resizeEvent(). Therefore, I kept getting some default size and not the actual size after Qt had properly placed the widget.

Marking as SOLVED.

Ahh. And since i did via a button, i was way past resizeEvent()

Thank you for updating.
