For FileMaker, the new TextView.ShowFontPanel function can show the font dialog and let user change the font settings. For MacOS, the function will show the system font panel, which allows you to adjust font information asynchronously.
For Xojo, the new TextArea.WinShowFontPanelMBS function can show the font dialog for a text area. Please use NSColorPanelMBS class and NSTextViewMBS usesFontPanel property for MacOS. The panel floats and allows to change font information for current text area.
In both cases, the dialog shows with current font selection, than user can change them and the new font settings are applied to the current selection in the text.
Changes are coming to next prerelease of our FileMaker and Xojo Plugins. If you like to test today, please email us.
