QWizard - mandatory fields

[slava]

Per the manual the * make the field in QWizardPage manadory, i.e. the button "Next" enables only when that field is filled.

I do:

registerField("field*", lineEdit);

and that works fine with QLineEdit but the same thing doesn't fly with QTextEdit. I do:

registerField("field*", textEdit, "plainText");

(I have to add "plainText" since textEdit is not a default property of QWizardPage)
and that doesn't work - the button "Next" does not get enabled when that textEdit gets filled.
I've tried:

registerField("field*", textEdit, "plainText", "textChanged");

didn't help either...

registerField("field*", textEdit, "plainText", SIGNAL(textChanged()));

Thank you very much, this is working now.
Can I ask one more quesiton?
Is it possible to change mandatority of the fielf later as a condition from some event? Like if a user chooses "Yes" in the comboBox, the field is mandatory, if user chooses "No", the field is not madatory. I have tried:



Page::Page (QWidget *parent)
: QWizardPage(parent)
{
.....
registerField("field*", lineEdit);
....
}


void Page::event()
{
if (comboBox->currentIndex() == 0) registerField("field*", lineEdit)
else registerField("field", lineEdit)
}

... i.e. put the "field" with the * or without it?

It might prove to be easier to simply connect QComboBox::currentIndexChanged() to QWizardPage::completeChanged() and re-implement QWizardPage::isComplete().

Thank you very much! :)

And the last question, please....
I have sorted out those mandatory fields thing, but the last thing I need to resolve is the size of the pages.
Whatever size I put for the QWizardPages to be it does not change anything, I can not strach the window by a mouse and there is no maximize button at the top of the window.
I have tried
resize(...., ...)
etc, but nothing helped...

You could try passing Qt::Window as second parameter to QWizard constructor if you want to make it appear as an ordinary window instead of a dialog.

[slava]

sorry, how do I do that, in the header file?

[jpn]

QWizard wizard(parent, Qt::Window); // <---
wizard.addPage(...);
wizard.addPage(...);
...
wizard.exec();

[slava]

I did it. The "maximize" button appeared but when I press it it streaches out the window to the maximum only vertically, the horizontal size still stays the same :confused:

[jpn]

Did you set any maximum sizes (widths) and/or did you adjust any size policies?

Edit: Oh, and which platform are you working on? Could you edit your user profile to indicate that? Thanks.

[slava]

not for the whole form. I have some size policies for the widgets and spacers inside the form so they streaches out correctly but no size policies for the whole form.
I did the pages in QT Designer, then converted them by uic and inserted the result into my program. In the Designer in the Form Preview I have the maximize button and it work fine, but when I insert it to the overall program I get that trouble.
I work on Windows for now.

I can assure you that it works with minimal test wizard. Did you subclass QWizard? If so, I'd suggest trying out with a plain QWizard to see if your subclass does something faulty. Furthermore, if it doesn't resolve the problem, try leaving out page by page to see which page could cause it.

[slava]

I found it! It was the pictures at the top and at the left which was set by setPixMap, they were limiting the sizes of the window, once I took those off the window got able to be any size.
thank you! :)
