Wild idea.

Reimplement void QLineEdit::focusOutEvent ( QFocusEvent * e ) and check what QLineEdit::validator()::validate() returns.

So you want to revert to original value in the text lenght is < 7 ?
You can use focusInEvent to save the original text in a qstring and focusOutEvent to revert.

ui->line_edit_font1->setInputMask("\#NNNNNN");

Then I can't input anything since it wants me to input all seven digits at the same time (copy paste works, but I can't type the digits one by one).

That is strange, btw my example was wrong. The format
for Hex-Digits is "HHHHHH". I am pretty sure this should work.
But I can not try it out at the moment. Can you try again with the
format:
ui->line_edit_font1->setInputMask("HHHHHH");

Thanks! Will test it out tomorrow Didn't know there was an input mask for hexes already existing

I can't see such signals in Qt Creator when I right click the lineEdit and select "Go to slot...".

They aren't signals. They are virtual methods. You have to reimplement those methods to use them.

I don't know how you can use this in Qt Designer, but you can use those methods like this:

mylineedit.h
PHP Code:
#ifndef MYLINEEDIT_H
#define MYLINEEDIT_H

#include <QLineEdit>

class MyLineEdit : public QLineEdit
{
    Q_OBJECT
public:
    MyLineEdit(QWidget *parent = 0);

protected:
    void focusOutEvent(QFocusEvent *event);
    void focusInEvent(QFocusEvent *event);

};

#endif // MYLINEEDIT_H 
mylineedit.cpp
PHP Code:
#include "mylineedit.h"

MyLineEdit::MyLineEdit(QWidget *parent) :
    QLineEdit(parent)
{
}

void MyLineEdit::focusInEvent(QFocusEvent *event)
{
    //Save text from line edit
}

void MyLineEdit::focusOutEvent(QFocusEvent *event)
{
    //Restore text if it is not valid
}

Sorry for changing the subject, but the GConfItem problem still remains for both D-Livil and me..

I use WinXP, and I'm afraid I can't install libs using Madde, or is it possible?

I've downloaded libgq-gconf-dev_0.2-3+0m5_armel.deb from the package page,
Then I unpacked everything into:
E:\NokiaQtSDK\Maemo\4.6.2\sysroots\fremantle-arm-sysroot-1030-slim\usr
and added your suggestion to src.pro:

But I still can't include GConfItem..
Copying doesn't seem like the right way to do it, but I'm clueless.

==================================================

I did manage to include GConfItem by putting these files in my project, but those files also had their own includes, and it seemed endless to me.
It wouldn't build because I don't have those headers.

Another thing.. I see "#include <gconf/gconf.h>" here and there, but in my setup it's "#include <gconf/2/gconf/gconf.h>". I didn't change anything manually, just a straightforward Nokia Qt SDK install.
The #include lines in those headers point to <gconf/....h>, so that's a dead end.


I hope I don't bother anyone too much about this, but any help would be great

Well.. I think it's solved

Use system("command");
But be careful with system commands

For instance, when you use
Code:
system("gconftool-2 -R /apps/osso/hildon-desktop/views");
It outputs this:
Code:
 current = 1
 active = [1,2,3,4]
 /apps/osso/hildon-desktop/views/1:
  bg-image = /home/user/MyDocs/.images/abstract1_01.jpg
 /apps/osso/hildon-desktop/views/2:
  bg-image = /home/user/MyDocs/.images/abstract1_02.jpg
 /apps/osso/hildon-desktop/views/3:
  bg-image = /home/user/MyDocs/.images/abstract1_03.jpg
 /apps/osso/hildon-desktop/views/4:
  bg-image = /home/user/MyDocs/.images/abstract1_04.jpg
I'll write how to catch that output in a QString tomorrow, time for some sleep first..


I've been able to set backgrounds with the following:
Code:
system('gconftool -s /apps/osso/hildon-desktop/views/1/bg-image -t string "/home/user/MyDocs/.images/abstract1_01.jpg"');
(For every desktop)
