Detailed Description

HPrintTable is a print preview and printer dialog, which can print a HTable or HList or HPlainDataMatrix objects. When you create this object, a popup dialog will appear with a print preview.

This class will generate the printed document according the meta data class (HTable/HList/HPlainDataMatrix) and the data will came from these class too.

HTable *mytable=...
...
HPrintTable *d = new HPrintTable(this,mytable);
d->exec();
delete d;
...

or you can print a result of a query

HSqlHandler h;
HPlainDataMatrix *pdm = h.submitNResultQuery(3,"SELECT name,age,address FROM peoples;","Error occured");
HPrintTable *d = new HPrintTable(this,pdm);
d->exec();
delete d;
delete pdm;

signal

The gui uses this signal to pass the refresh request to the HDataField descendants. This printing class won't use this signal, but I left this signal here avoid the connect error warnings.
