How to set QDate global variables
-
Hello everyone, this is my first time here to ask something.
I have some editDate in ui, in GUI, and it is troublesome to set a QDate variable for every declaration.
to Explain more clearly, I have the following:
void MainWindow::on_pushButtonTestDate_clicked()
{
QDate A = ui->dateEditA->date();
QDate B = ui->dateEditB->date();
// ........some codes
}void MainWindow::on_pushButtonTestDate2_clicked()
{
QDate A = ui->dateEditA->date();
QDate B = ui->dateEditB->date();
// ........some codes}
My question is:
How to make those QDate A, QDate B etc. global variable, define one time somewhere and can be used in every "void MainWindow::...."?Not quite sure if I expressed easily to be understood or not.
But this problem really really stuck me for a lot of days, and made me not able to move on for the work....Thank You All!

Hi and welcome
To make a variable available to all function of mainwindow ,
you just need to make it part of the class.
so in mainwindow.h
class Mainwindow:: public QMianwindow {
private:
QDate A;
QDate b;
};Its called a member variable. and is "global" to all functions of the class.
