FlexColorDialog: Using a single Picture Box for mutliple color swatches

[roy_043]

When I started using ODCL I was playing around with color dialogs. I was trying to create a flexible color dialog where the color swatches are configurable and ACI and true colors can be mixed in the same dialog. I have named the result 'FlexColorDialog'. The FlexColorDialog can be a replacement for the default AutoCAD/BricsCAD color dialog if, for example, you want to offer a limited choice of colors.

The ODCL dialog uses a single control (a Picture Box). The Lisp code may be of interest for other projects where the clicked coordinates of a Picture Box need to be analysed.

Note: I use BricsCAD 13.

Edit 1:
RGUS has stumbled upon an error. The error may be caused by the fact (?) that the function (dcl_GetOLEColorValue) does not accept an RGB-list in AC 2013. In BricsCAD 13 this is not a problem. I have updated the Lisp file.

Convert the first (dcl_GetOLEColorValue) argument to a (float) in order to avoid the DXF code problem.

Owen do you mean this?

Code (autolisp) Select Expand

(dcl_GetOLEColorValue (list (float (car rgbList)) (cadr rgbList) (caddr rgbList)))

Owen do you mean this?

Yes. This ensures that the list can't be interpreted as a DXF list.

Is this is a known bug of AC 2013?

Is this is a known bug of AC 2013?

Yes, and all other versions of AutoCAD.

To show the flexibility of FlexColorDialog here is a sample that will display all ACI colors.
