Is it possible to style QPushButtons separately from a qss stylesheet whether it has an icon applied or not?
Something like:
QPushButton[hasIcon="true"] {
background-color: green;
}
QPushButton[hasIcon="false"] {
background-color: red;
}
Thank you!

We are using a class on the html-element to determine whether the user is in dark or light mode of the app.
<html class="dark-mode"></html>
This class is added using Renderer2 in a service that detects the selected setting of the user. This works fine so far.
Now, we have to adjust all the components to look good in the dark mode as well. But the problem is Angular's ViewEncapsulation.
What we thought would come in handy, is to simply update the SCSS of the component:
.headline {
color: black;
.dark-mode & {
color: white;
}
}
Or in plain CSS:
.headline {
color: black;
}
.dark-mode .headline {
color: white;
}
Now this doesn't work, because the class .dark-mode seems to be encapsulated, as expected.
How can we solve this problem?
:host-context provides access to css classes above the :host. By using :host-context you are able to check if any of the parents of the host have a specific css class and apply styling:
:host-context(.dark-mode) h2 {
color: white;
}

I'm currently try to custom my QPushButton in Qt (PyQt in fact). So I set StyleSheet to do it.
But the problem is that I need to set this button to Default by setDefault to True.
And if I do that, I've a sort of color drool over ... how can I get rid of it?
Here is an example:
button = QPushButton('login')
button.setDefault(True)
button.setObjectName('login')
button.setStyleSheet(
"""
QPushButton#login {
background-color: #4caf50;
color: white;
border: none;
}
QPushButton:pressed#login {
background-color: #59b75c;
}
"""
)
Button appears green, but text is not fully white... I've try to set StyleSheet on QPushButton:default But it does not change anything at all
I can see you have a small error in your code. you gave us
QPushButton:pressed#login {
background-color: #59b75c;
}
but this does not work.
The correct way to do it is
QPushButton#login:pressed {
background-color: #59b75c;
}
also, be sure that after the '#' you use the objectName of the pushButton and not the text of the button.
Here is a link with some styleSheet examples
After long searches on the internet, I finally found how to do. I've to set outline to none to remove it.
QPushButton#login {
background-color: #4caf50;
color: white;
outline: none;
}
Then slobbery color disappear.
I want the treewidget header to look as if it's a label, so, I guess, I have to make it transparent? How do I do it?
I tried treeWidget->setStyleSheet("QTreeWidget::header {background-color: transparent}"); but it doesn't work.
The header is not a subcontrol of an itemview, thus QTreeWidget::header will not work. The header rather is a children widget of the view.
That means you could access the header via stylesheets with QTreeWidget QHeaderView {/*style here*/ }
For the background color of a header view you can check out the official Qt example.
In your case as you are setting the stylesheet directly to the view you can omit the parent so the following will do what you asked for:
treeWidget->setStyleSheet("QHeaderView::section { background-color: transparent; }");
In order to set the headers transparent, you have to add the following to the widget stylesheet:
QAbstractItemView QHeaderView {
show-decoration-selected: 0;
background: transparent;
}
QAbstractItemView::section QHeaderView::section {
show-decoration-selected: 0;
background: transparent;
}
Yesterday I decided to try Polymer 1.0 and I'm already facing difficulties when trying to styling the paper-toolbar.
The documentation says that the background colour can be changed by using:
--paper-toolbar-background
But how can I use it on CSS?
I tried the following:
paper-toolbar {
--paper-toolbar-background: #e5e5e5;
}
Also this:
paper-toolbar {
--paper-toolbar {
background: #e5e5e5;
}
}
But neither worked. What is the correct way to do it?
Thanks.
If you are styling it on your main page, then you have to apply styles using <style is='custom-style'>. This is to make Custom CSS Properties work.
Applying is relatively easy. paper-toolbar provides 2 custom properties and one mixin. --paper-toolbar-background is a property that changes the background color of the toolbar while --paper-toolbar-color changes its foreground color. --paper-toolbar is a mixin applied to the toolbar.
To use these properties is just the same as applying styles in your elements. As an example
<style is="custom-style">
paper-toolbar {
--paper-toolbar-background: #00f; /* changes the background to blue*/
--paper-toolbar-color: #0f0; /* changes the foreground color to green */
--paper-toolbar: {
font-size: 40px; /* Change default font size */
}; /* Notice the semicolon here */
}
</style>
I couldn't find a solution to this problem either until recently. I have two toolbars and I didn't want to change the CSS for all toolbars just the header toolbar.
To change the CSS for every toolbar, in your external css file add the following:
paper-toolbar.paper-toolbar-0 {
background: orange;
color: red;
}
However, that doesn't address the problem. To change a single paper toolbar based on a class like the following:
<paper-toolbar class="header">
...
</paper-toolbar>
The above uses the class called "header" so in my CSS I added:
paper-toolbar.header {
background: orange;
color: red;
}
... and it worked! Yay! That means with this you should be able to override any CSS of any of the other elements doing the same thing. This is completely untested but I think it should work like:
<elementName>.<classname> {
...
}
Hope this all helps!
I'm trying to make a universal CSS layout for a large application my companies working on. I ran into a problem while trying to style all asp:label's to look a certain way. I was having the same problem with buttons but I figured that out:
input[type="submit"] {
background: red;
}
that will make all the buttons have a red background....
So, does anyone know how to style asp:label's ??? Everything that I've attempted is listed below, but to no avail:
label {
background: red;
}
asp:label {
background: red;
}
input[type="label"] {
background: red;
}
Since a label just outputs a span, I would imagine that it's like this:
span { background-color:Red; }
