// 98/10/02 vtan: Multiple monitor bug fixes.
|
|
|
|
// Given an old monitor layout, a new monitor layout and a component
|
|
// this function makes sure that it is in the new layout using a
|
|
// monitor relative scheme. It tries to preserve the position
|
|
// relatively within a given monitor. If the resolution of the monitor
|
|
// changes then this needs to be accounted for also.
|
|
|
|
// Preserve the component within a given monitor if the monitor is the
|
|
// same HMONITOR but the GDI co-ordinates change.
|
|
|
|
// If the same monitor cannot be located then move the component to the
|
|
// nearest monitor and position it as best on that monitor.
|
|
|
|
// If all else fails then use the default component positioning
|
|
// algorithm. This should never happen.
|
|
|
|
// Preserve the component within a given monitor if the resolution
|
|
// changes. Preserve the size of the component by MOVING the component
|
|
// in the X and Y axis until the left or the top of the monitor is
|
|
// reached. When either axis reaches 0 then reduce the size of the
|
|
// component until it fits within the given new resolution.
