Hello Ching-Yen, Thanks for your suggestion. We have this feature in our wish-list. It will be implemented in one of the future releases. |

Hello, 'Snap to grid' feature is still only in wish-list and hasn't implemented yet. However if you are talking about grid background texture - you may change it's colors, but not it's size. To change colors please use these properties: WorkspaceBackColor1 & WorkspaceBackColor2 |

Hello, Alex, We tried to implement our own version of grid. We add the features of changing grid size interval and snapping to grid. We tried two ways to add grid : 1) use LineVObject 2) override draw method. The first method seems to work in the tested codes, but a little bit slow when updating grid property, in particular, changing from a large grid size interval to a smaller one. The second one is reasonable as regarding to speed of drawing grid. But the problem for the second one is that when we edit an object on the grid ( such as moving), the grid is wipped out ( see attached image). What can be the proper way to do this second one so that the grids are not wiped out when editing the objects on it? Thanks. mzhao attached the following image(s):

Hello, I've looked through source code of MultiLayerViewer - unfortunately it is not very flexible and not intended to be extended via inheritance. I recommend you to try another way. What do you think about creating special custom Grid object? It will be like SolidBackgroundVObject from MultiLayerImageEditor sample? In that case you shouldn't think about invalidation rectangles and double-buffering, just render grid in VObject's paint method. |
