 |
|
Is it possible to generate a CLICK event on a Table column header?
If I add the style COLUMNSORT the column headers become clickable but all the sorting is handled internally by Windows... is there some way I can know when a particular Column heading has been clicked?
I've thought of checking @mousepos() in relation to @dlgpos() but how do I know when a mouse button has been clicked?
Thanks.
EDIT: Just had a thought... perhaps the above in conjunction with a timer event and @mousedown ???

This works good for detecting a mouse click within the dialog but I need to know how to detect a Table Element Column Header click and which Column Header was clicked.
I suppose using your code as a base I could test for the coordinates clicked. However, with the Table Element the column order and width are not always static. |

Aslan,
The Table element sends a LVN_COLUMNCLICK message to the main window. However I know of no way to handle this message with VDS. Take a look here for more information. You would need a DLL to subclass the Main dialog and handle this message explictly.

I was going to try that with "Option MSGEVENT" but it seems that VDS can't handle negative message numbers.
Thanks for the reply on this and my VDS Bug post.
The HEX idea didn't work either 
I guess I'll have to put this one on my GadgetX list 
My guess is that even if "Option MSGEVENT" worked with this I would then have to handle all CLICK events for the Table. |

I'd already solved this (at least for my needs) back in early 2005 by using a TIMER event.
| Code: | # If left mouse button down
if @unequal(@lib(user32,GetAsyncKeyState,INT:,$01),0)
# Get effective column 1 width ie. width - cursor crosshair width (crosshairs for column width change)
%C = @diff(@sendmsg(@winexists(~TABLE1),@sum($1000,29),0,0),10)
# Get effective column 2 width
%S = @diff(@sendmsg(@winexists(~TABLE1),@sum($1000,29),1,0),10)
# Get mouse position relative to top left of Table
%X = @diff(@mousepos(X),@winpos(~TABLE1,L))
%Y = @diff(@mousepos(Y),@winpos(~TABLE1,T))
# If Mouse on Column 1 header ie. posn > left edge and < (left edge + column width) AND > top edge and < bottom edge
if @both(@both(@greater(%X,5),@greater(@sum(5,%C),%X)),@both(@greater(%Y,4),@greater(23,%Y)))
blah...blah...blah
# If mouse on Column 2 header
elsif @both(@both(@greater(%X,@sum(5,%C,15)),@greater(@sum(5,%C,10,%S),%X)),@both(@greater(%Y,4),@greater(23,%Y)))
blah...blah...blah

I'm not sure if I'm using the right message number
Just for my education how would these *_FIRST values be translated. They aren't hex or decimal, what are they?
From CommCtrl.h
//====== WM_NOTIFY codes (NMHDR.code values) ==================================
#define LVN_FIRST (0U-100U) // listview
#define LVN_COLUMNCLICK (LVN_FIRST-8)
#define HDN_FIRST (0U-300U) // header
#define HDN_ITEMCLICKW (HDN_FIRST-22)
#define HDN_ITEMDBLCLICKA (HDN_FIRST-3)
#define HDN_ITEMDBLCLICKW (HDN_FIRST-23)
Anyone?? |
