Detailed Description

This class handle a transition between two states (including previous/next buttons). Specific things can happen for CamiTK SCXML transition (e.g., apply the selected action before going to the next, closing components...)

The transition's name is set as the button's text.

Example:

<camitk:onTransition>
    <!-- Closing some components -->
    <camitk:close>
        <camitk:component type="ImageComponent" name="inputImage"/>
        <!-- even if image2 is modified, it will be closed without asking the user for a filename -->
        <camitk:component type="ImageComponent" name="generatedImage" force="true"/>
    </camitk:close>
</camitk:onTransition>

ActionTransition::ActionTransition	(	QPushButton *	sender,
		const char *	signal,
		QState *	sourceState = nullptr,
		bool	applyPreviousAction = true,
		QTextStream *	logStream = nullptr
	)

Member Function Documentation

addComponentToClose()

void ActionTransition::addComponentToClose	(	QString	compName,
		QString	compType,
		bool	force = false
	)

add a component's name and type to the list of component to close during the transition.

Set force to "true" in order to close the component independently of its modified flag.
