BTextView does not reformat its text when resized

[Trezker]

The textRect isn't resized when the BTextView instance is.

I looked through TextView.cpp and found that it should work properly if _ResetTextRect() is called in BTextView::FrameResized.

BTextView::FrameResized(float width, float height) {

BView::FrameResized(width, height);

+ _ResetTextRect();

_UpdateScrollbars();

}
