QCheckBox::isChecked() property is not working...

[Cutey]

Hi,

QCheckBox's isChecked() property is not working.
When I tried to check the corresponding QCheckBox object isChecked() by using the following code.

if (checkbox[i]->isChecked() == true)
{     }

if (checkbox[i]->isChecked() == true)
{     }

To copy to clipboard, switch view to plain text mode 

The strange is that rest of all property is working fine except the isChecked(). FYI, By default this is returning "false" value.

Please Please could any one give me a "workaround" for this problem.

Hi,
maybe try cb->checkState () == Qt::Checked

[triperzonak]

or maybe use

QCheckBox::setCheckState ( Qt::CheckState state )

(i think its more proper)

I tried these ways but nothing is working fine. Any more help..????

Erm?

// main.cpp
#include <QtGui>
 
int main(int argc, char* argv[])
{
	QApplication app(argc, argv);
	QCheckBox checkBox;
	qDebug() << checkBox.isChecked(); // "false"
	checkBox.setChecked(true);
	qDebug() << checkBox.isChecked(); // "true"
}

// main.cpp
#include <QtGui>

int main(int argc, char* argv[])
{
	QApplication app(argc, argv);
	QCheckBox checkBox;
	qDebug() << checkBox.isChecked(); // "false"
	checkBox.setChecked(true);
	qDebug() << checkBox.isChecked(); // "true"
}

Thanks a lot folks... At last I got my exact problem.

My problem is that QCheckBox/QRadioButton::isChecked() property in QScrollArea is returning FALSE by default .

It's strange for me. Could any one help me in this regard...
Please find the attachment where you could get my project's prototype. In that code checkout the "void OptionDlg:: processUserInput()" method.

Please Please Help me folkssssssssssssss.

My dear,

Please download the file and look into the files. There you could find all necessary files.
I did not attach as a separate files because forum supports only 5 files max to attach.

look at code and find the bug
