I am trying to be able to change the pen size of the small circle handles when i have a selection. (Could be box or circle).
I use the Imageenvect.ObjGripPen.Width := StrToInt(sSpinEdit_GripPenSize.Text);
Imageenvect.update;
That does not work.
What am i doing wrong?
Thanks.
Pierre

ImageEnVect1.ObjGripPen.Width := StrToIntDef(PenWidth1.Text, 5);
ImageEnVect1.Update;
works for me... this is different than
if iHObj <> -1 then
ObjPenWidth[iHObj] := StrToIntDef(BrushSize1.Text, 5);
Are you calling Update after you set the GripPenWidth?
Are you trying to set an objects pen width or the grips pen width?

this works:
ImageEnVect1.ObjGripPen.Width := StrToIntDef(PenWidth1.Text, 5);

That is what I thought. I know it used to work but not in my current code. Need to find out what is creating the problem then.
Thanks for checking.

Ok maybe what i want to do is different. i am calling
MouseInteract := MouseInteract + [miSelectPolygon];
so i have a rectangle selection with yellow circle and marching ants.
with that, i can copy or cut part of the image.
This is the width and size of the yellow circle i am trying to change.
I modified the vectorial demo with the code you gave me and that does not change.
Advice?
Thanks. |

procedure TForm1.BrushSize1Change(Sender: TObject);
var
i: Integer;
iHObj: Integer;
begin
if StrToInt(BrushSize1.Text) > 1 then
ImageEnVect1.HighlightedPixel := Point(-1, -1);
PenSizeScrollBar1.Position := StrToInt(BrushSize1.Text);
if (StrToInt(BrushSize1.Text) = 1) and ((Draw1.Down) or (Erase1.Down)) then
ImageEnVect1.Cursor := crIEPencil
else if (Draw1.Down) or (Erase1.Down) then
ImageEnVect1.Cursor := crIEBrush;
iHObj := -1;
if ImageEnVect1.ObjectsCount > 0 then
with ImageEnVect1 do
for i := -1 to SelObjectsCount - 1 do
begin
if i >= 0 then
iHObj := SelObjects[i];
if iHObj <> -1 then
ObjPenWidth[iHObj] := StrToIntDef(BrushSize1.Text, 5);
end;
ImageEnVect1.Update;
end;

Bill, i do not think this is what i am trying to do. It is more inline with the setgripstyle command.
I have attached the vectorial demo modified. You will have to run it as all the uneeded components are not visible when you do so. Only 2 are going to be left on the form. You'll know waht i am trying to accomplish the,
Thanks for the help.

You only have 2 choices. Set the grip pen width or the objects pen width and I have shown you how to do both. There are no other choices.

Oh Dear, you were not even talking about objects at all. You were referring to selection grips. Pierre, you should try to describe what you are trying to do better so you get the correct help.
ImageEnVect1.SetSelectionGripStyle(clWhite, clRed, bsSolid, strtointdef(Edit2.Text, 5), True, iegsCircle);

Well, that does not change the pen size :) I am aware of that. it makes the circle or the box bigger but does not change its thickness.
Sorry if i did not make my question clearer..
So, can that be done?
Apologize for all the confusion.

Unfortunately I still do not understand. What do you mean by "thickness"?

The thickness of the circle's pen. The more i think about it, it really does not matter as long i can change the size of the circle.
Never mind..
I really wasted a whole thread :(
Really appreciate your patience.
