Symbian dialog box usage

Id = EGeneralQuery;

Control = AVKON_DATA_QUERY

{

Layout = EFloatingPointLayout;

Label = "Enter value :";

Control = FLPTED

{

Maxlength = 10;

Min = 0;

Max = 100;

Default = 0;

};

};

}

};

}

STRUCT FLPTED

{

WORD maxlength = 18;

DOUBLE min =-9.9e99;

DOUBLE max = 9.9e99;

DOUBLE default = 0; // if! (Min <= default <= max), default = min.

}

The corresponding class of the floating point request dialog box is CAknFloatingPointQueryDialog. The following code is used as an example:

TReal value = 2.12345;

// Create dialog instance; value is a TReal reference that is used for // the editor

CAknFloatingPointQueryDialog * dlg = new (ELeave) CAknFloatingPointQueryDialog (value );

// Launch the dialog with resource R_DEMO_FLOATING_QUERY

If (dlg-> ExecuteLD (R_DEMO_FLOATING_QUERY ))

{

// OK pressed, value is the entered floating point number in the // editor.

}

In addition to the above, there are many types of Dialog in Symbian. Since I have not analyzed them, I will not give them one by one.
