How to style a table in QTextEdit

[HenkCoder]

@mchinand
I have a button that asks lets you create a table.

Is this the problem?

@HenkCoder
Have you tried plain setDefaultStyleSheet/setStylesheet("table{width: 100%; border-collapse: collapse;}") on something?

[HenkCoder]

@JonB
Sorry, I didn't understand what do you mean.

[mchinand]

Try just creating a table statically in code first to figure out how to get the stylesheet working.

[HenkCoder]

@mchinand
Ok.

Hi,

I think you are mixing two very different things here:

• Qt Style Sheet for customizing widgets
• QTextDocument Rich Text support shown through QTextEdit.

What you want to do is handled by the later. See the Rich Text chapter in Qt's documentation.

@SGaist Hello,
So, I got the border collapse working by doing this:

TextEdit *edit{getTabTextEdit()};
    QTextTableFormat format;
    format.setBorderCollapse(true);
    edit->textCursor().insertTable(lineNum, columnNum, format);

But I don't know how to set the table's width to change when the textedit's width changes and I don't know how to put its width to 100% as CSS does.

If memory serves well, something like:

format.setWidth(QTextLength(QTextLength::PercentageLength, 100));

@SGaist Yes! This was right!
Thank you so much, but I have one last question, sorry about that.
When I create the table it's like this:

but then when I type something in a cell the line separing the different cells adapts to the text. How do I avoid that?

I just wanted to expand the table to the TextEdit's width not also this feature.

[SGaist]

So you want the column to all take the same percentage of space ?

This post is deleted!

[HenkCoder]

@SGaist Yes, but in the way that they are distribuited, for example if I have 3 columns each one will be 33% but I don't want that they adapt with the text.

[SGaist]

Then QTextTableFormat::setColumnWidthConstraints looks like what you want.

[HenkCoder]

@SGaist And how do I do that? I tried to search online but I didn't find any solution that may help me, because they are reguarding QTableView.
I also checked the documentation but it doesn't explain much and I still don't know how to use it.
Thanks in advance.

[SGaist]

QTextLength oneThird = QTextLength(QTextLength::PercentageLength, 33);
QVector<QTextLength> constraints(3, oneThird);
format.setColumnWidthConstraints(constraints);

@SGaist This was the right solution! Thank you so much!
