Basic stuff here...

[MrShawn]

Can you provide a link to your specific example?

@Uberlinc It should be

ui->buttonBox

[Uberlinc]

Do you mean:

#include <QtWidgets>

#include "gotocelldialog.h"
#include "ui_gotocelldialog.h"

GoToCellDialog::GoToCellDialog(QWidget *parent)
: QDialog(parent)
{
setupUi(this);
Ui->buttonBox->button(QDialogButtonBox::Ok)->setEnabled(false);

QRegExp regExp("[A-Za-z][1-9][0-9]{0,2}");
lineEdit->setValidator(new QRegExpValidator(regExp, this));

connect(buttonBox, SIGNAL(accepted()), this, SLOT(accept()));
connect(buttonBox, SIGNAL(rejected()), this, SLOT(reject()));

}

void GoToCellDialog::on_lineEdit_textChanged()
{
Ui->buttonBox->button(QDialogButtonBox::Ok)->setEnabled(
lineEdit->hasAcceptableInput());
}

This yielded "Expected Primary Expression before ->"
(as well as the original two errors.)

I tried it with a Ui::buttonBox and it gave "buttonBox is not a member of Ui"

Suggestions?

Thanks.

@Uberlinc said in Basic stuff here...:

Ui

[Uberlinc]

I can find the code listings, but not the zip file.
Am I missing it here?

@jsulm
It uses the old ? / other way with ui
class GoToCellDialog : public QDialog, public Ui::GoToCellDialog
:)

[Uberlinc]

Okay, yes the downloaded version works.

The only thing that I can think of is that when creating the form, I selected "Dialog" instead of "Widget."
I must have missed that the first time around.

Would this have caused this problem?

Thanks.

@Uberlinc
well for
"buttonBox was not declared in this scope."
i would guess on something with the UI and maybe left
over files in your build folder.
Using Dialog and not widget should not have changed the name of buttons / if it was created.

[Uberlinc]

Okay.
I guess this is something that will come easier to me with more experience.
Thank you to all who assisted.

I will push on!

@Uberlinc
well push on and it will be super :)
Sometimes one needs to clean build folder. ( as in delete all in it)
