QUESTION
here's my problem: I'm using Qt, I've got two QLineEdits (name, author) and one QTextEdit (description) in my form. I need to set placeholders for each of them, so i wrote this code:
...ANSWER
Answered 2022-Mar-08 at 09:59There is preety easy way of doing this programatically.
You can change the QPalette
of your QLineEdit
and QTextEdit
and modify the QPalette::Text
with setColor
.
Another way of doing the same is catching signal if it is empty
or not and setting stylesheet.
https://doc.qt.io/qt-5/stylesheet-examples.html There is no reference of doing this in QT documentation.
If you want to look about complex examples other than this:

QUESTION
I am creating a stylesheet .qss
file for the GUI. I am trying to add the QToolButton
method autoRaise
to the style sheet as:
ANSWER
Answered 2021-Dec-15 at 20:42The autoRaise
(without a final "D") is a Qt property.
The :syntax
is used for pseudo states, normally indicating a state of the widget or a generic property.
They are predefined and common to all widgets, even if some states are only supported by some widgets (like :read-only
for a text widget) and based on the CSS pseudo-classes; see the full list of supported pseudo states.
If you want to set the style based on a property, you must properly use the property selector syntax:
QUESTION
Is it possible to change the QSizePolicy
property from the stylesheet?
So far I know every QWidget
has the property sizePolicy
. But the QSizePolicy
constructor takes two arguments; so I'm not sure how to set this property from a QSS file. Also calling:
ANSWER
Answered 2021-Dec-03 at 07:49It seems it is not possible out of the box. I will have to subclass whatever QWidget
I want and add two Q_PROPERTIES
for each direction of the QSizePolicy
. See this thread.
QUESTION
I want to use a QGroupBox which will be checkable, but i don't the content widgets of QGroupBox to be disabled when the QGroupBox checkbox is Unchecked.
checked : bool This property holds whether the group box is checked
If the group box is checkable, it is displayed with a check box. If the check box is checked, the group box's children are enabled; otherwise, the children are disabled and are inaccessible to the user.
By default, checkable group boxes are also checked.
I want to have a checkbox in QGroupBox title bar, but i don't want the above feature to be applied.
The checkbox logic will be select-all, select-none, so when the checkbox is unselected the user can modify inner QGroupBox checkbox elements.
I want to keep an interface-ui like the following:
Maybe i have to use a QFrame with QPaintEvent or QSS stylesheet, but i am not expert with this.
Edit: I also want triState for QGroupBox checkbox if possible.
