If i have several objects on an image and i click with my mouse in an empty spot on the image (a spot without objects underneath), i want to have nothing selected. And if there was something selected previously, everything should be deselected unless i click directly on an object.

How can i achieve that? I know it is easy, but for the sake of it i canīt find the parameter.


Thanks guys

Hi

Are you referring to TImageEnView Layers or TImageEnVect Objects?

I guess i could use a TImageEnVect but I would prefer to use the TImageEnView component if possible.

TImageEnView does not support objects... only TImageEnVect supports objects. If you own version 8.0x of ImageEn then you can use the new layers class (TIELayer)as an "object layer".

TIELayers in verision 8.0x supports "if there was something selected previously, everything should be deselected unless I click directly on an object." but with layers the "object" can be an image, a line, a polyline, or a shape.

This new TIELayer class is much more functional with TImageEnView than the older TImageEnVect. I recommend you obtain the laatest version and then read about layers in the help file.

If you use layers then you can set the size of the layers grips:
TImageEnView.SetLayersGripStyle

Declaration

procedure SetLayersGripStyle(GripColor1, GripColor2: TColor; GripBrushStyle: TBrushStyle; GripSize: Integer; Shape: TIEGripShape);
Description

SetLayersGripStyle determines the appearance of layers grips.

Parameter Description
GripColor1 grip border color
GripColor2 grip brush color
GripBrushStyle brush style
GripSize size in pixels of the grip
Shape specifies the grip shape

Example

ImageEnView1.SetLayersGripStyle(clWhite, clWhite, bsSolid, 5, iegsCircle);



With TImageEnVect you can set the objects grip size:

TImageEnVect.ObjGripSize

Declaration

property ObjGripSize: integer;

Description

Specifies the grip's size as shown when an object is selected.

Also see TImageEnVect vs TIELayers topic in the on-line help file.
