Use MainWindow ui in another class?

[pditty8811]

How do I use the ui-> property or attribute of MainWindow from another class(class called GetInfo).

Here is the function I want to move to another class:

@void MainWindow::grabDate(){

ui->lblDateChange->setText("August 5, 1940");

}@

I'd like to move it to another class called GetInfo. So I would think it would look like this:

@void GetInfo::grabDate(){

ui->lblDateChange->setText("August 5, 1940");

}@

Its a simple label that I change the text of. I launch it within MainWindow with grabData();

Also, how do you create an object of MainWindow class in another class? Is that even possible.

Can I do this to create object of MainWindow in GetInfo class?:

@MainWindow objMainWindow;@
or
@
MainWindow objMainWindow = new MainWindow;
@
Please help.
Thanks.

I don't know what is your purpose but I can guess you look for a rapid way to create widgets in your application; then you would not want to touch the Ui::MainWindow as it should manage your ui logic, I mean it should remain created in main.cpp; for widgets creation by designer just add other designer's form providing code for creating widgets having a QWidget's parent

anyway, regarding your code:

bq. Can I do this to create object of MainWindow in GetInfo class?:

MainWindow objMainWindow;

this is enough to create a QMainWindow object in your class but since ui is created in MainWindows class's constructor:

@MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)@

and is private, you need a public getter for it in MainWindow

hope this help! :)

Cheers!

What is a public getter?
