qspinbox

With a QSpinBox is it possible to display the thousand separator of a number while user enter it like 10,000 Which is the best way to do that ? pnezis You could subclass QSpinBox and reimplement the textFromValue which is responsible for the display of the value to the spinbox widget. A possible implementation could be the following: QString MySpinBox::textFromValue(int value) { return this->locale()->toString(value); } Using locale is the best way since it will display the separator based on the user's settings. i know this is late but this may help other people. i used this to update the

I need to implement a QSpinBox control which should be able to process int64 values as it's minimum & maximum values. Current implementation only supports int32 values. End of the day my QSpinBox should accept any value between 9223372036854775807 and -9223372036854775808 What do I need to do, if I'm to achieve this by subclassing QAbstractSpinbox ? Derive from QAbstractSpinBox . Add a QValidator to the QLineEdit to only allow valid int64 values. Add a property called value to provide access to the int64 member that actually holds the value. Reimplment stepBy(int steps) to modify the number.

I have a control with several QSpinBox objects inside a QScrollArea. All works fine when scrolling in the scroll area unless the mouse happens to be over one of the QSpinBoxes. Then the QSpinBox steals focus and the wheel events manipulate the spin box value rather than scrolling the scroll area. I don't want to completely disable using the mouse wheel to manipulate the QSpinBox, but I only want it to happen if the user explicitly clicks or tabs into the QSpinBox. Is there a way to prevent the QSpinBox from stealing the focus from the QScrollArea? As said in a comment to an answer below,

I am trying to set the background color for a double spin box, and I am not sure what function I should use. I saw some function called SetBackgroundRole which accepts a Qt::ColorRole , but I am not sure how to use this one as well. Kindly let me know, what's the simple way to change the background color of a QComboBox or QDoubleSpinBox ? Jérôme Using a QPalette isn't guaranteed to work for all styles, because style authors are restricted by the different platforms' guidelines and by the native theme engine. To make sure your background color will be correct, I would suggest to use the Qt
