Get font info OUT of a widget

mpersico has asked for the wisdom of the Perl Monks concerning the following question:

Plenty of examples out there showing how to create a font and set a widget to use it, but how do I GEt the font information OUT of an existing widget? I want to know its size (height), so that given how many lines I have, I can intelligently resize the height.

Thanks

G'day mpersico, Whenever you post a question here that's asking for information related to a module, please ensure you specify which module you are referring to. Vague references to fonts and widgets (as you have here) give no hint as to which of the many Perl GUI modules you're using. Providing a link to the module is even better — see What shortcuts can I use for linking?. I noted a few of your past nodes asked about Tk. Assuming that's what you're still using, the information you want can be found in the Tk Font documentation. This lists a number of methods which seem to do what you want, e.g. `fontMetrics()`, `fontMeasure()`, etc. -- Ken	[reply] [d/l] [select]

ask the widget for the information, use configure	[reply]

assuming this is about Tk, add `use Tk::WidgetDump; $mainWindow->WidgetDump; MainLoop;` to your program and see if it has the details, see Tk::options See also Tk::Style	[reply]
