Detailed Description

A file open/save dialog box.

This is a Juce-based file dialog box; to use a native file chooser, see the FileChooser class.

To use one of these, create it and call its show() method. e.g.

{
    WildcardFileFilter wildcardFilter ("*.foo", String(), "Foo files");

    FileBrowserComponent browser (FileBrowserComponent::canSelectFiles,
                                  File(),
                                  &wildcardFilter,

Constructor & Destructor Documentation

FileChooserDialogBox()

FileChooserDialogBox::FileChooserDialogBox	(	const String &	title,
		const String &	instructions,
		FileBrowserComponent &	browserComponent,
		bool	warnAboutOverwritingExistingFiles,
		Colour	backgroundColour,
		Component *	parentComponent = nullptr
	)

Creates a file chooser box.

Parameters

title	the main title to show at the top of the box
instructions	an optional longer piece of text to show below the title in a smaller font, describing in more detail what's required.
browserComponent	a FileBrowserComponent that will be shown inside this dialog box. Make sure you delete this after (but not before!) the dialog box has been deleted.
warnAboutOverwritingExistingFiles	if true, then the user will be asked to confirm if they try to select a file that already exists. (This flag is only used when saving files)
backgroundColour	the background colour for the top level window
parentComponent	an optional component which should be the parent for the file chooser. If this is a nullptr then the dialog box will be a top-level window. AUv3s on iOS must specify this parameter as opening a top-level window in an AUv3 is forbidden due to sandbox restrictions.
