setInputMask prevent the use of spaces and avoid the sense that something's written

[hakermania]

Hello.
I have a lineedit and I have set its input mask to nnnnnn (numbers+letters) but I have two major problems:
1) I don't want when I click to the lineedit the cursor to go to the end(it goes to the X position where X is the number of the 'nnnn' I have set to the input mask), as there is something written to the lineedit, while it isn't.
2) I want also to prevent the user from inputting spaces, is this possible?

1) I don't want when I click to the lineedit the cursor to go to the end(it goes to the X position where X is the number of the 'nnnn' I have set to the input mask), as there is something written to the lineedit, while it isn't.

use :

ui->lineEdit->setCursorPosition(x);

ui->lineEdit->setCursorPosition(x);

To copy to clipboard, switch view to plain text mode 

where x is the position where you want the cursor to be.

2) I want also to prevent the user from inputting spaces,

use the validator :

QRegExpValidator *noSpaceValidator=new QRegExpValidator(QRegExp("^[A-Za-z0-9]+"),ui->lineEdit);
 
     ui->lineEdit->setValidator(noSpaceValidator);

QRegExpValidator *noSpaceValidator=new QRegExpValidator(QRegExp("^[A-Za-z0-9]+"),ui->lineEdit);

     ui->lineEdit->setValidator(noSpaceValidator);

To copy to clipboard, switch view to plain text mode

I'd like to use this but the is not a slot that says on_lineedit_focused/clicked
ui->lineEdit->setCursorPosition(x);

Take a look at QWidget::focusInEvent() and related event handlers.

I'd like to use this but the is not a slot that says on_lineedit_focused/clicked
ui->lineEdit->setCursorPosition(x);

this should do the trick :

connect(ui->lineEdit,SIGNAL(editingFinished()),this ,SLOT(editFinshied()));
 
 
void MainWindow::setCursor()
{
    ui->lineEdit->setCursorPosition(3);
    disconnect(ui->lineEdit,SIGNAL(selectionChanged()),this ,SLOT(setCursor()));
 
}
 
void MainWindow::editFinshied()
{
    ui->lineEdit->selectAll();
    connect(ui->lineEdit,SIGNAL(selectionChanged()),this ,SLOT(setCursor()));
 
}

connect(ui->lineEdit,SIGNAL(editingFinished()),this ,SLOT(editFinshied()));


void MainWindow::setCursor()
{
    ui->lineEdit->setCursorPosition(3);
    disconnect(ui->lineEdit,SIGNAL(selectionChanged()),this ,SLOT(setCursor()));

}

void MainWindow::editFinshied()
{
    ui->lineEdit->selectAll();
    connect(ui->lineEdit,SIGNAL(selectionChanged()),this ,SLOT(setCursor()));

}

To copy to clipboard, switch view to plain text mode 

good luck !

Use a validator instead of an input mask.
