I am trying to make a QPushbutton that will increase in size to fit the text platform independently.
The text can be very long and I need the button to size itself so that all the text can be visible.
For example: I have a button with text "Restore defaults" , it is visible in win 7 . When i run this in mac os , only a part of the text ("tore defaults") is displayed.
Could anyone tell me how to solve this problem, to make all the text appear on the button.
QPushButton should already do that by default. Check your form in Qt Creator and see if "Maximum Size" is set to something other than the default. If so, set both width and height to 16777215 (or click on the small red arrow next to the property).
If you are manually setting the size in code, you can use the sizeHint property to get the right dimensions:
button->resize(button->sizeHint().width(), button->sizeHint().height());

I am using Qt via PySide6/PyQt to create a QTextEdit widget which fills the main window. As it accumulates text from the user, I would like to dynamically zoom out (using .zoomIn / .zoomOut) to keep all the text visible on screen at once.
I am not quite sure how to go about detecting if the text is overflowing in the text box.
Is there a Signal for this or some other obvious way to detect this that I am not seeing?
I'm working with qtpropertybrowser right now and I want to expend this with a new ability. When I click on the editor, it shows me a QLabel and a QToolButton, with the button I can choose a imagefile, the filename will be shown on the QLabel. When I left editor, it shows me the image. I wrote my own manager and editorfactory, all is working. But it shows me the image only in size of an icon ( I used the valueIcon methode for this). Is there a way to change the height of the line so the image shown is bigger?
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 have a QDialog I'm working with. It is made somewhat like a QMessageBox. I noticed that the size of the QMessageBox (and the size of its label) depends on the size of the message displayed.
How would I make the size of my QDialog adjust automatically like a QMessageBox? Presently my QDialog contains a button box and a label, and the QDialog is layout Vertical.
(I know I could just use the message box directly but eventually I will have more complex dialogs.)
Automatic solution:
Use layouts and set size policies to QSizePolicy::Expanding. In QtDesigner, once all your children are placed on your QDialog, then click on the Adjust Size button next layout ones. Your QDialog will be automatically resized at runtime.
Manual solution:
The QWidget class has a method adjustSize that resize the QWidget to fit its content. Just call it when all children are set.
Set your dialog to be expanding, and very small. Then, be sure to set your message before showing the dialog. When shown, it will try to find its proper size, based on the size of the objects it contains. (This happens recursively, so if the dialog isn't the direct parent of the label in which you show your message, make sure everything between the label and the dialog is set to use layouts.)
A TIP : if you try to use "adjustSize()" function when dialog is hidden, it may not be works fine. It would be better to use it after the "show()" function.
