QCheckBoxes

[arjita]

I am new to Qt ..can nyone tell me how can I add around 36 checkboxes in a wizard???

Do you use Qt Creator or Qt Designer? You can do this using Qt user-interface.
Otherwise you should create pointers and objects in your ui-class constructor (example from Qt Doc):

@
QCheckBox *checkbox = new QCheckBox("Case sensitive", this);
@

The best way to use Checkboxes is to use them inside QGroupBox.
Hope it helps.

Please read "QCheckBox":http://qt-project.org/doc/qt-5.0/qcheckbox.html documentation. QCheckBox inherits "QAbstractButton":http://qt-project.org/doc/qt-5.0/qabstractbutton.html and "QWidget":http://qt-project.org/doc/qt-5.0/qwidget.html so you can add it to a layout as a standard widget.

I'd suggest to re-think your GUI design. Do you really expect your users to find their way through 30+ checkboxes on a single page of a wizard? Is that a usable interface?

If you must present that many checkboxes, and they are all on the same level, considder using a list with checkable items. Make sure you add a filter above the list to the user can trim down the list quickly to only the relevant items.

I think use dynamic checkboxes.

This is my code, but this is C#.

@private void GenerateDynamicControls(int amount)
{
//Clear existing
pContainer.Controls.Clear();

        for (int i = 0; i < amount; i++)
        {
            //Create the Textbox
            TextBox dynamicTextbox = new TextBox();
            dynamicTextbox.Name = "dynamicTextbox" + i.ToString();
            dynamicTextbox.Width = 290;
            dynamicTextbox.Height = 20;
            dynamicTextbox.Left = 9;
            dynamicTextbox.Top = 10 + (dynamicTextbox.Height * i) + (10 * i); //initial + height + padding
            dynamicTextbox.Text = @"This is textbox number " + (i + 1).ToString();

            //Create the Button
            Button dynamicButton = new Button();
            dynamicButton.Name = "dynamicButton" + i.ToString();
            dynamicButton.Width = 75;
            dynamicButton.Height = 23;
            dynamicButton.Left = dynamicTextbox.Left + dynamicTextbox.Width + 5;
            dynamicButton.Top = dynamicTextbox.Top; //Center the button vertically to textbox
            dynamicButton.Text = "Show";
            dynamicButton.Click += new EventHandler(Button_Click); //hook the Click event

            //Add them to the container
            pContainer.Controls.Add(dynamicTextbox);
            pContainer.Controls.Add(dynamicButton);
        }
    }@

Andre said right,36 checkBox in a single form are not good for interface!
but! if you are newbie, u can use this method for generate dynamically controls :
@
for(int i=0;i<37;i++){
QCheckBox *chkbox = new QCheckBox();
chkbox->setText("test");
chkbox->setParent(ui->groupBox);
}
@

all of properties can be include in the "for" statement.
have a good code ;)

I am using 36 checkboxes for vertices in a graph .Checkboxes will consist of alphabets and digits and user will be required to check the box corresponding to vertices in his graph...

Boy, it sure sounds I should be glad I don't have to use your application... Anyway, best of luck!
