@class wxWrapSizer

|
|
A wrap sizer lays out its items in a single line, like a box sizer -- as long
|
|
as there is space available in that direction.
|
|
Once all available space in the primary direction has been used, a new line
|
|
is added and items are added there.
|
|
|
|
So a wrap sizer has a primary orientation for adding items, and adds lines
|
|
as needed in the secondary direction.

@a orient determines the primary direction of the sizer (the most common

case being @c wxHORIZONTAL). The flags parameter can be a combination of

the values @c wxEXTEND_LAST_ON_EACH_LINE which will cause the last item

on each line to use any remaining space on that line and @c wxREMOVE_LEADING_SPACES

which removes any spacer elements from the beginning of a row.

Both of these flags are on by default.
