add multiple QCoombox using loop

Hello,

How can one add multiple QComboBoxes using a for-loop?

Like we do in qcheckbox as:

Code:

---

for (int k=0; k<3 ; k++)
{
   mCheckBox = new QCheckBox(tr("input %2:").arg(k));
}

---

Is there a similiar way to add multiple QComboBoxes aswell?

PS: i could not find the .arg() object in QComboBox :-(

Thanks!

arg() is a method of QString.

Okay, then what is the way of doing it for QComboBox?

I have a combobox next to checkbox. For checkbox I used the code as mentioned above.
Now I want to repeat this combination using a for-loop.

How can this be achieved?

Code:

---

for(int i=0;i<n;++i) {
  QComboBox *cb = new QComboBox;
  // ...
}

I have already tried this. But the comboBoxes are not repeated. Only the checkboxes are repeated. Following is my code:

Code:

---

QGridLayout* ChannelLayout1 = new QGridLayout(this);
QGroupBox   *GroupBox1        = new QGroupBox(tr("Box"));
 
		for(k=0; k < 5 ; k++)
		{
		   QCheckBox *mCheckBox1 = new QCheckBox(tr("input %2:").arg(k));
		   QComboBox *mComboBox1 = new QComboBox;
 
		   for(int i=0; i < 3; i++)
                            {
                                 mComboBox1->addItem(tr("Item %2").arg(i));
                            }
 
		   mComboBox1->setFixedWidth(200);
		   ChannelLayout1->addWidget(mCheckBox1);
		   ChannelLayout1->addWidget(mComboBox1,0,1,0,20);
		}
GroupBox1->setLayout(ChannelLayout1);

Please help.

You are putting all comboboxes in one place in the layout.

Ya, i figured that out. There was one more problem besides that in lines 15 and 16. The corrected lines are as follows:

Code:

---

15. ChannelLayout1->addWidget(mCheckBox1,k,0);		   
 16. ChannelLayout1->addWidget(mComboBox1,k,1);

Thanks!

@wysota:

Thanks for ur advice. I have sorted it out! :-)

You are trying to set the same layout to two widgets.
