Then next step is that you can either create a resource file and add the stylesheet. If your class inherits from a QWidget then to make the stylesheet work you need to override the paintEvent and write. Can you paste the implementation code for your class. Also try Browse in your stylesheet.
I tried the following but it does not work either. Thank you SAM but the difference from my application is that Browse is created from a login class and not from the main window. Could you please test it?
Stylesheet of login works. But for browse not. Also, I don't use a style sheet file, I use the style sheet editor when i open login form and right click, select change style. Just for the test , you can use write the required styles to a. Thats what I made, but it does not work on my MAC. I don't use setstylesheet but when I used it once, it worked. Setstylesheet will hardcode it. We can change this by specifying subcontrol-position and subcontrol-origin to anchor the indicator differently.
We can also use top and left to move the indicator by a few pixels. This positions the myindicator. Since red seems to be our favorite color, let's make the text in QLineEdit red by setting the following application-wide stylesheet:.
However, we would like to give a visual indication that a QLineEdit is read-only by making it appear gray:.
At some point, our design team comes with the requirement that all QLineEdit s in the registration form with the object name registrationDialog to be brown:. For example, to set a background-image that scrolls with the scroll bar:. The main difference is that a tristate QCheckBox has an indeterminate state. We will look at an example where the drop down button of a QComboBox appears "merged" with the combo box frame.
The title bar and the buttons of a QDockWidget can be customized as follows:. If one desires to move the dock widget buttons to the left, the following style sheet can be used:. Let us look at an example that moves the QGroupBox 's title to the center. To create a line edit with rounded corners, we can set:. The password character of line edits that have QLineEdit::Password echo mode can be set using:. To provide a special background when you hover over items, we can use the ::item subcontrol.
For example,. Individual items of a QMenu are styled using the 'item' subcontrol as follows:. The QProgressBar 's border , chunk , and text-align can be customized using style sheets. However, if one property or sub-control is customized, all the other properties or sub-controls must be customized as well. For example, we change the border to grey and the chunk to cerulean. This leaves the text-align , which we customize by positioning the text in the center of the progress bar. A margin can be included to obtain more visible chunks.
In the screenshot above, we use a margin of 0. For a QPushButton with a menu, use the ::menu-indicator subcontrol. Checkable QPushButton have the :checked pseudo state set.
The QScrollBar can be styled using its subcontrols like handle , add-line , sub-line , and so on. Note that if one property or sub-control is customized, all the other properties or sub-controls must be customized as well.
The left-arrow and right-arrow have a solid grey border with a white background. As an alternative, you could also embed the image of an arrow.
If you want the scroll buttons of the scroll bar to be placed together instead of the edges like on macOS, you can use the following stylesheet:. QSizeGrip is usually styled by just setting an image. If you want to change the color of the slider parts before and after the handle, you can use the add-page and sub-page subcontrols. For example, for a vertical slider:. QSpinBox can be completely customized as below the style sheet has commentary inline :. The grip or the handle is customized using the ::handle subcontrol.
We can provide a background for the status bar and a border for items inside the status bar as follows:. Note that widgets that have been added to the QStatusBar can be styled using the descendant declaration i. For a tab widget that looks like above, we make use of negative margins. Negative values draw the element closer to its neighbors than it would be by default. The resulting stylesheet looks like this:. This is possible with the selection-background-color property and the syntax required is:.
In the following snippet the indicator background-color in unchecked state is customized:. The background and the handle of a QToolBar is customized as below:.
The QToolButton has no menu. See Customizing QPushButton for an example. See Customizing QPushButton for an example of the usage of the menu-indicator pseudo state. In this case, we style it as follows:. QToolTip is customized exactly like a QLabel. In addition, for platforms that support it, the opacity property may be set to adjust the opacity. The branches of a QTreeView are styled using the ::branch subcontrol. The following stylesheet color codes the various states when drawing a branch.
When styling a QPushButton , it is often desirable to use an image as the button graphic. It is common to try the background-image property, but this has a number of drawbacks: For instance, the background will often appear hidden behind the button decoration, because it is not considered a background. In addition, if the button is resized, the entire background will be stretched or tiled, which does not always look good.
It is better to use the border-image property, as it will always display the image, regardless of the background you can combine it with a background if it has alpha values in it , and it has special settings to deal with button resizing. The numbers after the url gives the top, right, bottom and left number of pixels, respectively.
