|
A font chooser dialog shows installed fonts.
|
|
The dialog is non-modal with its owning dialog,
|
|
which is usually a plugin procedure's dialog.
|
|
When a user selects a font,
|
|
the dialog calls back but the dialog remains open.
|
|
The chosen font is only a choice for the owning widget
|
|
and does not select the font for the context.
|
|
The user can close but not cancel the dialog.
|
|
The owning dialog can close the font chooser dialog
|
|
when the user closes or cancels the owning dialog.
