BStringView

Derived from: public BView

Declared in: be/interface/StringView.h

Library: libbe.so

Summary

A BStringView object draws a string that the user can neither select nor edit. BStringView object are typically used as labels for your app's UI. If you need to present text that can be selected and/or edited, wse a BTextView object.

Constructor and Destructor

BStringView()

	BStringView(BRect frame, const char *name, const char *text,       uint32 resizingMode = B_FOLLOW_LEFT | B_FOLLOW_TOP,       uint32 flags = B_WILL_DRAW) BStringView(BMessage *archive)

Initializes the BStringView by assigning it a text string and the system plain font (be_plain_font). The frame, name, resizingMode, and flags arguments are passed unchanged to the BView constructor.

The frame rectangle needs to be large enough to display the entire string in the current font. The string is drawn at the bottom of the frame rectangle and, by default, is aligned to the left side. A different horizontal alignment can be set by calling SetAlignment().

~BStringView()

	virtual ~BStringView()

Frees the text string.

Static Functions

Member Functions

Alignment() see SetAlignment()

"Archived Fields"

Archive() , see

	virtual status_t Archive(BMessage *archive, bool deep = true) const

Calls the inherited version of Archive(), then adds the string and its alignment to the BMessage archive.

AttachedToWindow()

	virtual void AttachedToWindow(void)

Sets the BStringView's low color and its background view color to match the background color of its new parent view.

See also: BView::AttachedToWindow()

Draw()

	virtual void Draw(BRect updateRect)

Draws the string along the bottom of the BStringView's frame rectangle in the current high color.

SetAlignment() , Alignment()

	void SetAlignment(alignment flag) alignment Alignment(void) const

These functions align the string within the BStringView's frame rectangle and return the current alignment. The alignment flag can be:

B_ALIGN_LEFT	The string is aligned at the left side of the frame rectangle.
B_ALIGN_RIGH T	The string is aligned at the right side of the frame rectangle.
B_ALIGN_CEN TER	The string is aligned so that the center of the string falls midway between the left and right sides of the frame rectangle.

The default is B_ALIGN_LEFT.

SetText() , Text()

	void SetText(const char *string) const char *Text(void) const

These functions set and return the text string that the BStringView draws. SetText() frees the previous string and copies string to replace it. Text() returns the null-terminated string.

Archived Fields

The Archive() function adds the following fields to its BMessage argument:

Field	Type code	Meaning
"_text"	B_STRING_TYPE	Text displayed in the view (present only if it is not NULL).
"_align"	B_INT32_TYPE	Alignment of text in frame.
