I'm using TImageEnMView component to show current layers.
When MView thumbnail (layer) is clicked, actual layer is selected.
However, any change (drawing) on selected layer (bitmap) is not reflected on the thumbnail, because MView works with internal bitmaps (no matter which StoreType is selected).
Is there a possibility to set MView to work in "shared" mode, so that MView item points to actual layer (IEBitmap)?
I'm still working with ImageEn ver.3.0.2, so I don't know if such possibility exists in newer versions.

Hi
It is not possible in yours or a newer version, however you can simply use a TTimer to perform a delayed update of the MView whenever the layer is changed (and update the relevant image of the grid).

Thanks.
However, I've already written a class inherited from TMS advscrollbox and call it TQuasiMView. It contains panels with small ImageEnViews (created in runtime with AddImage method). ImageEnView has method SetExternalBitmap which is just what I need.
Now, I don't need to reload layers into MView, simple refresh is enough.
It looks like ImageEnMView, so I called it QuasiMView:
Another question, regarding layers, actually VisibleBox property.
Setting: PaintView->Layers[PaintView->LayersCurrent]->VisibleBox = true;
does not show Box if MouseInteract is empty.
When MouseInteract contains something (for example miMoveLayers), box is shown.
What I need is a possibility to show box around layer without adding elements to MouseInteract. Is it possible?

I do not think that s possible with the current version, but maybe Nigel will have an idea.

Hi
Yes, I see what you are trying to do, but I don't think it would be possible.
You can test this by setting the external bitmap of each of your view images as follows
QuasiMView.ImageEnView[ I ].SetExternalBitmap( ImageEnView1.Layers[ I ].Bitmap);
Selection boxes are not shown if no mouse selection method is specified.
