How to remove Scroll bar of QCombo Box

I am able to hide the scroll bar arrow of the combobox using following line,


comboBox->setStyleSheet("QComboBox::drop-down::down-arrow {image:url}");


but my problem is that when I hide this arrow the space for this arrow in to the comboBox remain there so the letter which I enter in to the comboBox made off-centre,
So how can I remove this space in to the comboBox and show my letter centre,
Here I attached the picture, through the help of this picture you can clearly understand my problem,

Hm, is this task homework you have to do?

And you won't find an easy solution, because removing the "drop down" from a combobox is nonsense (like having a button without a click-able area). So no build in solution for that, but you can subclass the style and change the drawing there. Or use a proxy style.

Perhaps you really want a QLineEdit, QCompleter and QValidator.

Or perhaps you don't want to use widgets at all. This looks more like a platform game than a UI of a utility program.

Thank you all for your valuable reply, I fill that I can solve my this problem using QLineEdit, I make my code through this,

Now I wanted to know that how to read value which i return inside the QLineEdit,
I try this, but it didn't work,

QString *a;
a=LineEdit->text();
qDebug("%s",a);

but it shows the error can not convert QString to QString in assignment,


Then I try this
qDebug("%s",LineEdit->text());
can not pass object of non trivially copyable type.

So please suggest me how can I read the value of LineEdit....

Are you sure the message didn't say it couldn't convert QString to QString* in assignment?

yes wysota..... is there any other way through which i can get this value???

Do you understand the difference between QString and QString*?

Yes I know it very well but it didn't work so i try QString *......
Have you any solution how to read value which was written inside the LineEdit....?????????????????????????????????????? ???????????????????

So why are you trying to assign QString object to QString pointer? You read the value properly, using QLineEdit::text() but then you fail to use it correctly by trying to assign it to a pointer.

Hello friends Thanx for your replies,
I make my application using following code,

Code:

---

QString p;
p=lineEditBox->text();
 
QStringList stringList= p.split("",QString::SkipEmptyParts);
for (int i = 0; i < stringList.size(); i++)
{
if(i==stringList.size()-1)
{
lineEditBox->clear();
lineEditBox->setText(stringList.at(i));
}
}

---

... :)

}

I don't try to find nice words: This horrible. Do you understand what this code does? Do you really think you need a loop to set the last word of an array to your line edit. Also why are you clearing the edit before setting a new text? With setting a new text, line edit clears itself automatically.

Yes lykurg I complete my task using this....
If you have any other simple suggestion then please write it..... :)

Hmm... what is the purpose of this line?

Code:

---

QStringList stringList= p.split("",QString::SkipEmptyParts);

I got this solution from above thread.....

But this "solution" does something much different than your code. So again, why did you put this line there?
