- ========================================================================
- To get right mouse button clicks, simply use vq_mouse and get the correct
- information from VDI, or use event_dclick for the double click information.
- ========================================================================
-
- evnt_dclick() is for setting the double-click timer. You can NOT get
- double clicks from it!! vq_mouse()? Are you insane? Do NOT mix AES
- functions with the VDI functions when you don't have to, and PLEASE
- make the program event driven!! DO you really expect everyone to use
- a 0ms timer on the evnt_multi and poll for mouse events? You want people
- to call evnt_multi() and vq_mouse() in a tight loop just to get the
- right button clicks? THIS IS WRONG. And for hot-objects I suppose
- we should call wind_find and objc_find in this tight loop too.
-
- 3 of the most taxing AES calls plus a VDI call in a tight loop eating as
- m,uch CPU time as it possibly can. It is WRONG. Please do NOT tell
- others to do this. Evnt_multi() can handle up to 8 buttons, please
- see my code for a full explaination of this. No timer events required.
-
- ========================================================================
- This works, but you have to enable BOTH button DOWN flags, and you need to
- set the number of clicks to 1. However, you could use 2, but this is
- not recommended, as AES will be forced to wait for two mouse clicks, and will
- not stop at one.
- ========================================================================
-
- No, use the code I posted using the guidelines in the source. Set the
- number of clicks to the MAXIMUM number you want to recieve. However,
- if you wish to distinguish a press from a click, it may be best to set
- the maximum clicks to 2, to enable the delay (that is determined by the
- user with evnt_dclick() which is called in desk ACCs and CPXs), then
- you can just treat a double-click as a single click if you don't want
- double-clicks.
-
- So, it IS recommended to use a 2, actually, 0x0102 (258), but read the
- code. And the AES does NOT wait for two mouse clicks. It waits a
- pre-determined amount of time (in the ms range!) for multiple clicks
- to occur. This allows multiple clicks to be sent as one event and it
- gives the user time to release the mouse button. It will NOT wait until
- the mouse is clicked twice .. it is a MAXIMUM clicks, not MINIMUM.
-
- I don't think you know what the GEM standards are. You are defining
- your own and doing everything that you accuse other people of doing as
- far as breaking interface guidelines and standards. Try using GEM
- correctly and see what happens.
