Hie..
I am using QT to make a small program. How should I get the text from the QLineEdit named lineEdit1 and put it into another QTextLabel ??
the command

i tried

textLabel1.setCaption(/*what do i write here*/);

does it differ when you use designer (hence you write this code in a slot of a button in a *.ui.h) and when you use cpp (hence you write this code in a slot of a button in a .cpp) file ???

Please help

The QLineEdit class has a "text" property, so you cold try this:
Furthermore, you can connect the signal from lineEdit1, "textChanged(QString)" to the textLanel1 slot, "setText(QString)", and then whenever the line edit is modified, the label will be updated automatically.

Hi.
I wrote exactly this in the slot for a button which is evoked when the signal clicked() is emitted from the button. But is shows some compiling error. I guess it is because I am using designer and I wrote that code in .ui.h file which somehow is not supporting the same command. So what is the solution? Should I stop working with designer coz I am getting a lot more issues with improving the functionality of many of the buttons.
Or is there a way to get out of this trauma of having to write long code just to get something like a textbox tested of some small property.???

Please help.

Also...if after getting the text can i convert it to a double value by function (atof()) ??

Okie here is what i do..

void (this is a slot_name))
{
Qstring a;
a = lineEdit->text();
static float b =0;
b+= atof(a);
std::cout <<b<<endl;
label->setCaption(a);
}

here everything works but the last line. the labels caption is not changing?????
and this was a hand coded program.
If I make a program by designer, how do I get this code running?? Where do I write these lines?????

At least in Qt3, you should add
at the end. Probably the same with version 4...
