Every method of TImageEnMView.InsertImage calls InsertImageEx(idx, imsAlways). Because InsertImage passes imsAlways for TIEMSelectMode, it always selects the image just inserted. I needed a way to prevent this.
Since InsertImageEx has the SelectMode parameter (which defaults to imsNever), this is a minor change request. I solved this by adding a private field in TIECustomMView and a public property in TImageEnMView, then changed each call to InsertImageEx to use the new property value rather than imsAlways. I set the default value of the new property to imsAlways to maintain current behavior.
The other change that I made was to add a condition where InsertItemEx calls DoSelectionChanged, such that it is only called when SelectMode <> imsNever. I added the same condition in TIECustomMView.DoChanged.
Obviously, there may be a better way to implement this request. And there may be scenarios that I have considered.
Thanks,
Jon |

Hi Jon
You can email me for a beta that includes the selection option, iemoDontSelectOnAdd, which does this. Also OnSelectionChange if this is used.

procedure TIECustomMView.DoChanged() still calls DoSelectionChanged even when iemoDontSelectOnAdd is set.

I solved this in my version although I'm not thrilled with my solution.

Hi Jon
You can email me for a beta update to improve this (there will be still be some instances of SelectionChanged to avoid breakage for legacy users, but that should be rare with iemoDontSelectOnAdd).
