Controls whether map windows redraw automatically.
SetMapRedraw(string map_name, boolean redraw_flag)
|
Argument |
Contents |
|
map_name |
The name of the map, or null for the current map |
|
redraw_flag |
If "True" (the default), the map is redrawn automatically. If "False" map drawing is suppressed except for explicit calls to RedrawMap() |
When a map is changed (e.g., by adding or removing layers, changing the scope or display settings) the map is marked to be redrawn automatically. The automatic redraw takes place when whenever its window is uncovered (e.g., when a dialog box is hidden, or another window that obscures a portion of the map is moved).
SetMapRedraw() prevents automatic map redraws, so that the map is drawn only when RedrawMap() is called.
|
SetMapRedraw("My Map", "False") |
// Turn off the automatic drawing... |
|
... |
// Do a bunch of processing that affects the map |
|
SetMapRedraw("My Map", "True") |
// Turn the flag back on |
|
RedrawMap() |
// Redraw the map |
