i have item_master form where in i enter product specifications.
theres is one text_item to enter color of the product i want to put a button next to the field, when it is pressed a color pallatte should appear like how we have in the form builder. user will get chance to see the color and pick of his choice.whichever color gets selected,the text_item background should get filled with that color or the color name should appear in its own color in the text_item.

i can see i nice color List item above, when i am filling this post. can a list item designed like this be possible in form6i. where all color names get displayed in their own color?

i would be greatful if someone suggest me the steps for doing this and helps me with the code. TYVM

pls download the attached file and change the extention to zip,
unzip the file and run the wapidemo.fmx (Windows API Demo)from the same directory (i.e. use open with , and select forms runtime, as it requires current directory path to run correctly)

in dialog functions tree item, there is a option choose_color


======
Choose_Color pops up the standard color selection dialog, and allows the user to select a color.

Arguments:
<Red> A PLS_INTEGER variable to take the degree of Red-ness of the selected color. If you initialise this variable with a value, then the dialog will display this value as an initial selection
<Green> A PLS_INTEGER variable to take the degree of Green-ness of the selected color. If you initialise this variable with a value, then the dialog will display this value as an initial selection
<Blue> A PLS_INTEGER variable to take the degree of Blue-ness of the selected color. If you initialise this variable with a value, then the dialog will display this value as an initial selection
<RaiseExceptions> TRUE or FALSE(Default) If set to TRUE, then if the dialog is cancelled, the explicit PL/SQL exception NO_DATA_FOUND will be raised.

The function returns an integer value which reflects the combined RGB value.

============
sample code.
/*-- Sample Generated Code --*/
declare
 iRed PLS_INTEGER := 128;
 iGreen PLS_INTEGER := 0;
 iBlue PLS_INTEGER := 255;
 iResult PLS_INTEGER;
begin
 iResult:= Win_API_Dialog.Choose_Color( iRed, iGreen, iBlue, TRUE);
 ...
end;


===========================
then use

set_item_property(itname,BACKGROUND_COLOR,'r255g255b255');


replace the last color code r255g255b255 with those picked in the color dialog.
