stackedwidget for different class which they have their own .cpp , .h, and .ui

mrjj

Hi
If I understand you correctly,
you can maybe use the promote feature.

Say you have
UI A,B,C
B and C contains widgets like buttons etc.

on A you put a stacked widget
and on page 1 it has all of B, and on page 2, it has all of C
and they still live in their own UI files. ?

That you can do via promote. In short you place a QWidget in the stacked paged and it will be replaced
by all widget from an UI file. When you run the program.
Note: select QWidget as parent, not dialog when you create B,C.

If its not what you mean, then sorry :)

@mrjj I did put a widget on the stackedWidget. Even though it is a QDialog, I created a widget inside of it. I was able to call the files and add them into the stackwidget. My question now is how do I call a qpushbutton created from Page1?

mrjj

@marlenet15
well , say the place holder widget is called Wid2, (the one you promoted)
then you can access any widget using the normal

ui->Wid2->SomeButton

its being created in the ui_xx file for the UI that contains the promoted widgets.

Each widget should be self-contained so what exactly do you want to do with that button from another widget in your stack ?

marlenet15

I want to press that button to go the next page that is in the stack

SGaist

In that case and from a design point of view, does it really belong to a widget inside the stack ?

marlenet15

Yes it does.

SGaist

Then add a signal to that widget that will forward the button clicked signal. Something like nextPageRequested. That will be cleaner and easier to understand when you read the code.

marlenet15

I know but how am I supposed to access that widget when it is in another class?

connect(Page1->nextButton, SIGNAL(clicked()),this,SLOT(goToPage2()));

Where Page1 is the widget that contains the button "nextButton" and when you press it will go to Page2

SGaist

That's what I wrote: you don't access the button, you only connect Page1.

Are you trying to re-implement QWizard ?

marlenet15

Yes but I do not want to use QWizard since I don't want it in that style. The only similarity is that I can go from one page to another.
