Resetting Qt Style Sheet
- by mree
I've managed to style my QLineEdit to something like this:
void Utilities::setFormErrorStyle(QLineEdit *lineEdit)
{
lineEdit->setStyleSheet(
"background-color: #FF8A8A;"
"background-image: url(:/resources/warning.png);"
"background-position: right center;"
"background-repeat: no-repeat;"
"");
}
I called the function using
Utilities *util = new Utilities;
util->setFormErrorStyle(lineNoStaf);
The flow should be something like this:
User open form
User fill data
User submit data
Got error
Use setFormErrorStyle()
User edit the text in the QLineEdit and the style disappear
This function should be reusable over and over again, but how can I connect QLineEdit signal such as textChanged() to a function in other class that will reset the Style Sheet and then disconnect the signal so that it won't be running continuously every time the text changed ?
