QTableWidgetItem set background color on click (over stylesheet )
-
@nevdokimof
So far as I understand it, the whole point is that stylesheet entries override whatever you try to do in code, so you won't achieve it that way (unless @dheerendra knows better than I).When I need to do this, I do it by:
- Set a dynamic property on the item in code (I use a dynamic property named
class, personally; you might usecoloror whatever for this). See https://wiki.qt.io/Dynamic_Properties_and_Stylesheets & http://doc.qt.io/qt-5/stylesheet-examples.html#customizing-using-dynamic-properties. - Create rules in the stylesheet for the various property's values to produce the desired effect.
Is that what you would like to do?
[P.S. Funnily enough, I happen to have just looked at a new post https://forum.qt.io/topic/97783/style-text-in-qtextedit/4, that is using exactly the principle I use, saved me going find an example in my own code! You would adapt for your various
QTableWidget::itemrules, but that is the coding principle I recommend://StyleSheet QTextEdit[styleVariant="1"] { // Custom Style } QTextEdit{ // Default Style } // connect pushbutton clicked(bool checked = false) signal to onPushButtonClicked onPushButtonClicked(bool checked) { if(checked) textEdit->setProperty("styleVariant", 1); else textEdit->setProperty("styleVariant", 0); }.]
@JonB this would be the thing if I could get
QWidgetpresentation ofQTableWidgetItem, but then I would just set background color of widget.QTableWidgetItemitself doesn't contain membersetProperty(or similar), so I can't achieve what I want in your way. Thanks for advice tho, didn't know about widget dynamic properties. - Set a dynamic property on the item in code (I use a dynamic property named

@JonB this would be the thing if I could get

QWidgets... :( I'm having a think, if I have anything to add I'll get back.... -

When user clicks that "selects" the item, doesn't it? So have you tried
QTableWidget::item:selectedrule instead? -

QTableWidget::item:selectedrule instead?@JonB I don't want to allow user "select" (as Qt means it) items. In my case items are supposed to behave like regural push buttons.
The reason why I don't use
QPushButtons + vertical layout (or whatever) in first place is scroll bar inQTableWidget. -

Given that we're not achieving what you originally asked for: if you just want a scrollbar, what about using aQScrollAreaaround yourQPushButtons' layout, which is how to get a lightweight scroller without needingQTableWidget? -

@JonB yeah, that might be it. I'll try this way, you helped me a lot, thank you.
Original question is still unanswered though, would be interesting to know if there is a way to do what I've described in first post.
@nevdokimof
I believe your original question is indeed answered: "No, you cannot alterQTableWidgetItemdynamically while using a stylesheet precisely because it is not aQWidget".

Previously you talked aboutQTable..., now you're sayingQTree..... But the same is the case either way.QTableWidgetinheritsQTableView. It should be the case that anythingQTableWidgetdoes you could do yourself usingQTableView. TheQ...Widgets are effectively just a convenience implementation off theQ...View, they provide an "item-based table view with a default model" if that's what you want.However, I think you will have the same issues whether you use a
QTableViewor aQTableWidget. Why do you think aQTableView/QTreeViewwould solve your issue? -
I came cross the same problem. Any solution? After stylesheet is set for QTableWidgetItem, it seems impossible to change anything for example: background color. "QTableView::item{color:%5;border-color:%6;border:0px;padding-left:%7px;}" is used in qtablewidget and I would like to set different background color for every another row. Without stylesheet, padding can not be set.
