wxDialogBox::Iconize

void Iconize(Bool iconize)

If TRUE, iconizes the dialog box; if FALSE, shows and restores it. Note that in Windows, iconization has no effect since dialog boxes cannot be iconized. However, applications may need to explicitly restore dialog boxes under XView and Motif which have user-iconizable frames, and under Windows calling Iconize(FALSE) will bring the window to the front, as does Show(TRUE).
