I have a tab widget with two tabs in it in my Qt application. When I set the label text for a tab to a long word like 'Difference', some of the text goes out of the boundary of the tab and is not shown. How do I fix this so that the entire label text fits exactly in the tab?
Thanks,
Rakesh.
Qt receives that style from OS. By default on Windows text isn't truncated. You can set it manually using
QTabWidget::setElideMode( Qt::ElideNone );
I think elideMode would be helpful for you.
Try setting the value to Qt::ElideNone which will not show the ellipsis in the text, so I am guessing it might show the entire text.

i am trying to accomplish the following behavior with a QML TextArea:
I want single Words in the Text to be colored differently
I want the "select"-functions to be working for automated scrolling (user interaction is disabled)
There is a stream of text in the TextArea where one Word needs to be selected(highlighted). The user is requested to input some text elsewhere and press enter to proceed (not part of the question). After that the selection jumps to the next word and the last selected word is either colored green or red. There is only a small portion of the text visible (a few lines, managed by the TextArea height – not part of the question) and i need the text to scroll if the next word is out of that visible range .. therefore the selection is quite helpful because all interaction from the user – to scroll or select or whatever – is disabled (disabling is not part of the question)
my main problem is: if i use textFormat: TextEdit.RichText i can easily color the text how i like it to be (<font color=\"green\">{}</font>) but i cannot use the "select"-functions anymore because – as i would guess – the selection works on the "plaintext" and cannot correspond to the "richtext"-selection? Anyway selectWord() etc. does not work QTextCursor::setPosition: Position '-1' out of range is the result. But if i disable the RichText i don't know how to color the text. Maybe i could live without the selection if i could detect the current word – which would be colored blue etc. – and scroll if its out of the visible area to "fake" the selection behavior, but that's just a third option.
I would really either know how to color non-Rich Text or how to select Rich Text in a TextArea.
You can use QSyntaxHighlighter to highlight the words independent of the selection. See QQuickTextDocument and How to implement rich text logic on QML TextEdit with QSyntaxHighlighter class in Qt for more details.
When I'm make a button on the screen in the storyboard and have more text in it than the buttons width. The text just keep on going on a straight line past the buttons end. When this happens I want to have a line break so I can have the text on two lines, but I can't figure out how to get two lines of text in a button in the storyboard..
Any ideas how I can get this done in the storyboard?
Set Line Break to "Word Wrap":
Set the frame of the button whatever you want by the code and set Line break to "Word Wrap".
Hope it will solve your problem.
Not only should you "Word Wrap" the text but, you should also use the auto layout debugging tool and select the "add missing constraints."
For example, we have a QLabel with MaximumWidth set to 400.
When we try to display some text with pixel width more than 400, it's shown cut off.
Is there any way to make QLabel display this string in multiple lines without using QFontMetrics or the like?
If I understood your question correctly, you should use the setWordWrap function for your label, with true as its parameter.
QLabel lbl("long long string");
lbl.setWordWrap(true);
In order to show multiple lines in QLabel, right click on QLabel and select 'change rich text'. This brings up dialog where you can type the text as you want to see including enter key. Setting the word wrap is not required for this.
If you set the word wrap as well (in QLabel properties) than it will wrap each individual line in the Qlabel if it was longer than the real estate.
As another option to wrap text using Qt Designer, you can check the box under Property Editor for a QLabel:
I want to display a big string in a Qlablel for this I simply have created a label in the Qt GUI editor.
Then set the string with the Wordwrap property to "ON".
Here text is not coming to the next line itself. Instead, it's crossing the view region.
However, if I give an "\n" it works well.
How do I put up the big string in a label to display in a visible region?
label->setWordWrap(true);
See the QLabel::setWordWrap(bool on) documentation.
First, what does one call the ghost caption that appears in a text edit if that edit has no real text?
Second, has anyone invented that particular wheel for Flex text components?
Thanks
It's called a Watermark.
I'm not an expert on Flex but here is one example:
