copy string from text box

[Rekha]

how to copy a string from one text box to another textbox?
there are 2 text boxes, text1 and text2 and an enter button.. on pressing enter button contents from text1 widget should get transferred to text2..
only the function to copy from text1 to text2 is required..
Pls check the following code is correct

void update()
{
     QString str;
     str=text1->toPlainText();
     text2->setText(str);     
}

void update()
{
     QString str;
     str=text1->toPlainText();
     text2->setText(str);     
}

To copy to clipboard, switch view to plain text mode

What did you try so far? And what is a "text box"? QLineEdit? QTextEdit? QTextBrowser? ...

// line edit
lineEdit2->setText(lineEdit1->text());
 
// text edit
textEdit2->setPlainText(textEdit1->toPlainText());

// line edit
lineEdit2->setText(lineEdit1->text());

// text edit
textEdit2->setPlainText(textEdit1->toPlainText());

To copy to clipboard, switch view to plain text mode 

PS. QLineEdit offers a signal returnPressed().

pls help me out

You have just added a function update(), it's not declared as a slot. And why on the earth do you modify a file automatically generated by UIC? Next time you run UIC your modifies get overwritten.

See designer docs for Using a Component in Your Application.

You did not read the link, did you?

Don't modify the source code generated by the UIC (UI Compiler). Just include the .ui file in your project and go read this link again to see how to use it properly in your project. Pay special attention to sections "The Single Inheritance Approach" and "The Multiple Inheritance Approach" and choose one of them.

I have attached a small example illustrating how to do what I believe you want to do. The example uses the single inheritance approach.

Hi,

On the page :
http://doc.trolltech.com/4.1/designe...component.html
I have tried the :
The Multiple Inheritance Approach
with the :
A Dialog With Auto-Connect

The code is ( too ;-) ) simple.

Regards.
