Detailed Description

This class contains some static methods for showing native alert windows.

Member Function Documentation

◆ showMessageBox()

static void JUCE_CALLTYPE NativeMessageBox::showMessageBox	(	AlertWindow::AlertIconType	iconType,
		const String &	title,
		const String &	message,
		Component *	associatedComponent = `nullptr`
	)

static

Shows a dialog box that just has a message and a single 'ok' button to close it.

The box is shown modally, and the method will block until the user has clicked its button (or pressed the escape or return keys).

Parameters

iconType	the type of icon to show
title	the headline to show at the top of the box
message	a longer, more descriptive message to show underneath the title
associatedComponent	if this is non-null, it specifies the component that the alert window should be associated with. Depending on the look and feel, this might be used for positioning of the alert window.

◆ showMessageBoxAsync()

static void JUCE_CALLTYPE NativeMessageBox::showMessageBoxAsync	(	AlertWindow::AlertIconType	iconType,
		const String &	title,
		const String &	message,
		Component *	associatedComponent = `nullptr`,
		ModalComponentManager::Callback *	callback = `nullptr`
	)

static

Shows a dialog box that just has a message and a single 'ok' button to close it.

The box will be displayed and placed into a modal state, but this method will return immediately, and the callback will be invoked later when the user dismisses the box.

Parameters

iconType	the type of icon to show
title	the headline to show at the top of the box
message	a longer, more descriptive message to show underneath the title
associatedComponent	if this is non-null, it specifies the component that the alert window should be associated with. Depending on the look and feel, this might be used for positioning of the alert window.
callback	if this is non-null, the callback will receive a call to its modalStateFinished() when the box is dismissed. The callback object will be owned and deleted by the system, so make sure that it works safely and doesn't keep any references to objects that might be deleted before it gets called. You can use the ModalCallbackFunction to easily pass in a lambda for this parameter.

◆ showOkCancelBox()

static bool JUCE_CALLTYPE NativeMessageBox::showOkCancelBox	(	AlertWindow::AlertIconType	iconType,
		const String &	title,
		const String &	message,
		Component *	associatedComponent = `nullptr`,
		ModalComponentManager::Callback *	callback = `nullptr`
	)

static

Shows a dialog box with two buttons.

Ideal for ok/cancel or yes/no choices. The return key can also be used to trigger the first button, and the escape key for the second button.

If the callback parameter is null, the box is shown modally, and the method will block until the user has clicked the button (or pressed the escape or return keys). If the callback parameter is non-null, the box will be displayed and placed into a modal state, but this method will return immediately, and the callback will be invoked later when the user dismisses the box.

Parameters

iconType	the type of icon to show
title	the headline to show at the top of the box
message	a longer, more descriptive message to show underneath the title
associatedComponent	if this is non-null, it specifies the component that the alert window should be associated with. Depending on the look and feel, this might be used for positioning of the alert window.
callback	if this is non-null, the box will be launched asynchronously, returning immediately, and the callback will receive a call to its modalStateFinished() when the box is dismissed, with its parameter being 1 if the ok button was pressed, or 0 for cancel, The callback object will be owned and deleted by the system, so make sure that it works safely and doesn't keep any references to objects that might be deleted before it gets called. You can use the ModalCallbackFunction to easily pass in a lambda for this parameter.

Returns: true if button 1 was clicked, false if it was button 2. If the callback parameter is not null, the method always returns false, and the user's choice is delivered later by the callback.

◆ showYesNoCancelBox()

static int JUCE_CALLTYPE NativeMessageBox::showYesNoCancelBox	(	AlertWindow::AlertIconType	iconType,
		const String &	title,
		const String &	message,
		Component *	associatedComponent = `nullptr`,
		ModalComponentManager::Callback *	callback = `nullptr`
	)

static

Shows a dialog box with three buttons.

Ideal for yes/no/cancel boxes.

The escape key can be used to trigger the third button.

If the callback parameter is null, the box is shown modally, and the method will block until the user has clicked the button (or pressed the escape or return keys). If the callback parameter is non-null, the box will be displayed and placed into a modal state, but this method will return immediately, and the callback will be invoked later when the user dismisses the box.

Parameters

iconType	the type of icon to show
title	the headline to show at the top of the box
message	a longer, more descriptive message to show underneath the title
associatedComponent	if this is non-null, it specifies the component that the alert window should be associated with. Depending on the look and feel, this might be used for positioning of the alert window.
callback	if this is non-null, the box will be launched asynchronously, returning immediately, and the callback will receive a call to its modalStateFinished() when the box is dismissed, with its parameter being 1 if the "yes" button was pressed, 2 for the "no" button, or 0 if it was cancelled, The callback object will be owned and deleted by the system, so make sure that it works safely and doesn't keep any references to objects that might be deleted before it gets called. You can use the ModalCallbackFunction to easily pass in a lambda for this parameter.

Returns

If the callback parameter has been set, this returns 0. Otherwise, it returns one of the following values:

0 if 'cancel' was pressed
1 if 'yes' was pressed
2 if 'no' was pressed

◆ showYesNoBox()

static int JUCE_CALLTYPE NativeMessageBox::showYesNoBox	(	AlertWindow::AlertIconType	iconType,
		const String &	title,
		const String &	message,
		Component *	associatedComponent = `nullptr`,
		ModalComponentManager::Callback *	callback = `nullptr`
	)

static

Shows a dialog box with two buttons.

Ideal for yes/no boxes.

The escape key can be used to trigger the no button.

If the callback parameter is null, the box is shown modally, and the method will block until the user has clicked the button (or pressed the escape or return keys). If the callback parameter is non-null, the box will be displayed and placed into a modal state, but this method will return immediately, and the callback will be invoked later when the user dismisses the box.

Parameters

iconType	the type of icon to show
title	the headline to show at the top of the box
message	a longer, more descriptive message to show underneath the title
associatedComponent	if this is non-null, it specifies the component that the alert window should be associated with. Depending on the look and feel, this might be used for positioning of the alert window.
callback	if this is non-null, the box will be launched asynchronously, returning immediately, and the callback will receive a call to its modalStateFinished() when the box is dismissed, with its parameter being 1 if the "yes" button was pressed or 0 for the "no" button was pressed. The callback object will be owned and deleted by the system, so make sure that it works safely and doesn't keep any references to objects that might be deleted before it gets called. You can use the ModalCallbackFunction to easily pass in a lambda for this parameter.

Returns

If the callback parameter has been set, this returns 0. Otherwise, it returns one of the following values:

0 if 'no' was pressed
1 if 'yes' was pressed
