Slate基础使用说明

1. 简单教程

2. 要点说明     

2.1  TCommands以及TCommands基类

/** A base class for a set of commands. Inherit from it to make a set of commands. See MainFrameActions for an example. */
template<typename CommandContextType>
class TCommands : public FBindingContext

/**
 * Represents a context in which input bindings are valid
 */
class SLATE_API FBindingContext
	: public TSharedFromThis<FBindingContext>

2.2  FUICommandInfo

private:

	/** Input commands that executes this action */
	TArray<TSharedRef<FInputChord>> ActiveChords;

	/** Default display name of the command */
	FText Label;

	/** Localized help text for this command */
	FText Description;

	/** The default input chords for this command (can be invalid) */
	TArray<FInputChord> DefaultChords;

	/** Brush name for icon to use in tool bars and menu items to represent this command */
	FSlateIcon Icon;

	/** Brush name for icon to use in tool bars and menu items to represent this command in its toggled on (checked) state*/
	FName UIStyle;

	/** Name of the command */
	FName CommandName;

	/** The context in which this command is active */
	FName BindingContext;

	/** The bundle to group this command into. The bundle must have been added to the BindingContext first. */
	FName Bundle;

	/** The type of user interface to associated with this action */
	EUserInterfaceActionType UserInterfaceType;

	/** True if should we use long names for when getting text for input chords */
	bool bUseLongDisplayName;

2.3  FUICommandList

class SLATE_API FUICommandList
	: public TSharedFromThis<FUICommandList>

2.4  FUIAction

/**
 * Implements an UI action.
 */
struct SLATE_API FUIAction
{
	/** Holds a delegate that is executed when this action is activated. */
	FExecuteAction ExecuteAction;

	/** Holds a delegate that is executed when determining whether this action can execute. */
	FCanExecuteAction CanExecuteAction;

	/** Holds a delegate that is executed when determining the check state of this action. */
	FGetActionCheckState GetActionCheckState;

	/** Holds a delegate that is executed when determining whether this action is visible. */
	FIsActionButtonVisible IsActionVisibleDelegate;

	/** Can this action can be repeated if the chord used to call it is held down? */
	EUIActionRepeatMode RepeatMode;

2.5  UICommand

#define UI_COMMAND( CommandId, FriendlyName, InDescription, CommandType, InDefaultChord, ... ) \
