saving the state of the ui

[zgulser]

hi,

I wonder if there is possible to return the .ui class initial state. Actually, I want to change the contents of the ui file by a button click and I want the ui file come back to it's initial state just after another button click in the same window.

is this possible?

thanks in advance

You can save all properties of all widgets in a window and then reset them back when you need it.

I think QSettings is very convenient for such tasks.

To save a state use something like:



QSettings settings( "MyIniFile.ini", QSettings::IniFormat );
settings.beginGroup( "MyGroup" );
settings.setValue( "MyStateName", saveState(0) );
settings.endGroup();


To restore it use:



QSettings settings( "MyIniFile.ini", QSettings::IniFormat );
settings.beginGroup( "MyGroup" );
restoreState( settings.value( "MyStateName", QByteArray() ).toByteArray(), 0 );
settings.endGroup();


I develop mainly on Windows but prefer the INI storage format as it doesn't intefere with the registry and can be easily edited by hand (with the exception of states...).

You'll need to change your ini, group and state names accordingly (all the strings).

For more detailed work refer to QSettings.

Hope this helps.
