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.

I am new to Material UI and I am currently testing on TextField.
When the value is longer that the width of the field, you still can read the text with clicking on the field and drag to right.
I would like to ask if there is a way to change the font color (Or any other thing) if length of the string is longer than a certain value in order to indicate there are some texts left behind.
(Single line edit field is necessary since there are many fields required to show on screen)
Thank you very much!
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.
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 entered one space as a QLineEdit's text in the Qt Creator GUI Designer. I can see that the space is there in the designer wiew, but if I compile and run it, the space disapears. I want this space to be a QLineEdit's default text, how can set it, or tell Qt to do not delete that one space?
My guess is that space disappears because UIs are stored as XML and nodes consisting only of whitespace are strippd (see this question).
But you can set the space to the QLineEdit in the window's constructor:
ui->lineEdit->setText(" ");
If what you want is to have a default text when the widget is empty, use the setPlaceholderText(QString)
If you want to just set a initial value, then do it in the constructor of your app/widget/class with setText(QString)
Hoping to obtain the help of some Flex 3/4 gurus out there...
I am attempting to dynamically change the color of a subset/portion of text in a Spark TextArea control. Using the MX-based TextArea, I could leverage the mx.controls.textClasses.TextRange type and change the color directly as follows:
TextRange tr = new TextRange(theTextAreaControl, false, beginIndex, endIndex);
tr.color = somePredefindColor;
Input Parameters to TextRange constructor:
1st argument: The TextArea control that will provide access to the underlying textField property
2nd argument: Indicates the TextRange will not modify the content of the TextArea
3rd argument: The beginning index position in the TextArea text string
4th argument: The ending index position in the TextArea text string
How would I go about doing this for a Spark-based TextArea control? I am looking to dynamically change the font color for a range of text, not just the entire TextArea AND I cannot statically specify the font color. The problem I run into when trying to re-use the TextRange type is that the 1st argument is expected to provide the textField property, which is currently not on the Spark-based TextArea control. I thought about extending the Spark-based TextArea control to provide this accessor property but that seems like overkill and is probably not the best approach.
Any help would be greatly appreciated.
Thanks,
Michael
When manipulating Spark text components, you'll want to use the Text Layout Framework (TLF), which is built on top of the Flash Text Engine (FTE) that was introduced in Flash Player 10. It gives you major control over how the text is displayed (at the cost of being pretty complex.) Here's a good place to start: Using Text Layout Framework
