<modulesummary>Functions for wxIcon class</modulesummary>
<description><p>An icon is a small rectangular bitmap usually used for denoting a minimized application.
</p><p>It differs from a <seeerl marker="wxBitmap"><c>wxBitmap</c></seeerl> in always having a mask associated with it for transparent drawing. On some platforms, icons and bitmaps are implemented identically, since there is no real distinction between a <seeerl marker="wxBitmap"><c>wxBitmap</c></seeerl> with a mask and an icon; and there is no specific icon format on some platforms (X-based applications usually standardize on XPMs for small bitmaps and icons). However, some platforms (such as Windows) make the distinction, so a separate class is provided.
</p><p>Remark: It is usually desirable to associate a pertinent icon with a frame. Icons can also be used for other purposes, for example with <seeerl marker="wxTreeCtrl"><c>wxTreeCtrl</c></seeerl> and <seeerl marker="wxListCtrl"><c>wxListCtrl</c></seeerl>. Icons have different formats on different platforms therefore separate icons will usually be created for the different environments. Platform-specific methods for creating a <seeerl marker="wxIcon"><c>wxIcon</c></seeerl> structure are catered for, and this is an occasion where conditional compilation will probably be required. Note that a new icon must be created for every time the icon is to be used for a new window. In Windows, the icon will not be reloaded if it has already been used. An icon allocated to a frame will be deleted when the frame is deleted. For more information please see overview_bitmap.
