25 // TGCanvas and TGViewPort and TGContainer //
26 // //
27 // A TGCanvas is a frame containing two scrollbars (a horizontal and //
28 // a vertical) and a viewport. The viewport acts as the window through //
29 // which we look at the contents of the container frame. //
30 // //
31 // A TGContainer frame manages a content area. It can display and //
32 // control a hierarchy of multi-column items, and provides the ability //
33 // to add new items at any time. By default it doesn't map subwindows //
34 // which are items of the container. In this case subwindow must //
35 // provide DrawCopy method, see for example TGLVEntry class. //
36 // It is also possible to use option which allow to map subwindows. //
37 // This option has much slower drawing speed in case of more than 1000 //
38 // items placed in container. To activate this option the fMapSubwindows//
39 // data member must be set to kTRUE (for example TTVLVContainer class) //
40 // //
41 // The TGContainer class can handle the keys: //
42 // //
43 // o F7, Ctnrl-F - activate search dialog //
44 // o F3, Ctnrl-G - continue search //
45 // o End - go to the last item in container //
46 // o Home - go to the first item in container //
47 // o PageUp,PageDown,arrow keys - navigate inside container //
48 // o Return/Enter - equivalent to double click of the mouse button //
49 // o Contrl-A - select/activate all items. //
50 // o Space - invert selection. //
