If you are using the register in a kiosk mode, using a kiosk window manager is a simpler solution than the following. See Other_Resources#Other_resources.2Fideas.

640x480 Howto

Edit /LanePOS/register/xmlRegister/renderXmlRegister-Tk

cp LanePOS/register/xmlRegister/renderXmlRegister-Tk/renderXmlRegister-Tk \
LanePOS/register/xmlRegister/renderXmlRegister-Tk/renderXmlRegister-Tk-640x480

sub initDisplay
{
    #my($top) = MainWindow->new();
    $top = MainWindow->new();
    hideCursor($top);
    $top->title("L'anePOS: registerTk");
    # force 640x480 resolution
    $top->geometry('640x480');
    outerFramesUi($top);
    $entEntry->focus();
#    &Tk::MainLoop;
    $entEntry->update;
    return 1;
}

• Render the new register:

./renderXmlRegister-Tk-640x480 sample-touch-register.xml > my-register
./my-register

This will result in the app being forced to 640x480, but not all of the buttons can be seen:

Now all of the font sizes have to be mangled so the application fits in the space we gave it.

cp LanePOS/register/xmlRegister/sample-touch-register.xml \
LanePOS/register/xmlRegister/sample-touch-register-640x480.xml

• Render the new register:

./renderXmlRegister-Tk-640x480 sample-touch-register-640x480.xml > my-register
./my-register

• And now we should have something like this:
