1\section{\class{wxImageList}}\label{wximagelist}
2
3A wxImageList contains a list of images, which are stored in
4an unspecified form. Images can have masks for transparent
5drawing, and can be made from a variety of sources including bitmaps
6and icons.
7
8wxImageList is used principally in conjunction with \helpref{wxTreeCtrl}{wxtreectrl} and
9\rtfsp\helpref{wxListCtrl}{wxlistctrl} classes.

33
34\docparam{width}{Width of the images in the list.}
35
36\docparam{height}{Height of the images in the list.}
37
38\docparam{mask}{TRUE if masks should be created for all images.}

47
48\func{int}{Add}{\param{const wxBitmap\&}{ bitmap}, \param{const wxBitmap\&}{ mask = wxNullBitmap}}
49
50Adds a new image using a bitmap and optional mask bitmap.
51
52\func{int}{Add}{\param{const wxBitmap\&}{ bitmap}, \param{const wxColour\&}{ maskColour}}
53
54Adds a new image using a bitmap and mask colour.
55
56\func{int}{Add}{\param{const wxIcon\&}{ icon}}
57
58Adds a new image using an icon.
59
60\wxheading{Parameters}
61
62\docparam{bitmap}{Bitmap representing the opaque areas of the image.}
63
64\docparam{mask}{Monochrome mask bitmap, representing the transparent areas of the image.}
65
66\docparam{maskColour}{Colour indicating which parts of the image are transparent.}
67
68\docparam{icon}{Icon to use as the image.}
69
70\wxheading{Return value}
71
72The new zero-based image index.
73
74\wxheading{Remarks}
75
76The original bitmap or icon is not affected by the {\bf Add} operation, and can be deleted afterwards.

79
80\func{bool}{Create}{\param{int }{width}, \param{int }{height}, \param{const bool }{mask = TRUE},\rtfsp
81\param{int }{initialCount = 1}}
82
83Initializes the list. See \helpref{wxImageList::wxImageList}{wximagelistconstr} for details.

90
91Draws a specified image onto a device context.

100
101\docparam{y}{Y position on the device context.}
102
103\docparam{flags}{How to draw the image. A bitlist of a selection of the following:
104
105\begin{twocollist}\itemsep=0pt
106\twocolitem{{\bf wxIMAGELIST\_DRAW\_NORMAL}}{Draw the image normally.}
107\twocolitem{{\bf wxIMAGELIST\_DRAW\_TRANSPARENT}}{Draw the image with transparency.}

110\end{twocollist}
111}
112
113\docparam{solidBackground}{For optimisation - drawing can be faster if the function is told
