win32: detecting double click ? http://www.allegro.cc/forums/view/575032 Allegro.cc Forum Thread matthew@allegro.cc (Matthew Leverton) Mon, 10 Apr 2006 01:20:18 +0000

in windowed mode i can spy on the WM_LBUTTONDOWN mesages and log when they occur, this gives me suffecient timing information to detect double clicks.

but in fullscreen mode, WM_LBUTTONDOWN messages dont appear to be sent.
how can i detect double clicks ? accurately.
(polling the mouse_b) can not be done accurately.

i'll consider solutions that involve hacking allegro too.. as i think that is the only way its going to happen.

That isn't very elegant... sleeping multiple times in the poll function.

Also, why use show_mouse? Just draw_sprite() mouse_sprite to the x/y.

there were 2 other way i thought up but they involve variables . this the best metod out of the tree. plus this can be class independent.

is_doubleclick(); put that any where you want to check.

This is a windows prog? Check out WM_LBUTTONDBLCLK message.

What? That was the problem... it wasn't working for him full screen.

in windowed mode, i can see the WM_LBUTTON message, but in fullscreen mode i dont.

gezzz thouse sleeps are in Milli seconds I'm using 50 50, and it only activates when the mouse is pressed.

A bit offtopic: how do you make a window fullscreen? I think that doesn't mean it's maximized.

Maybe that's in some way related to why you're not getting those messages (I suppose you still get WM_CHAR and friends).

Marco.. i use set_gfx_mode(AUTO_DETECT_FULLSCREEN,

piccolo, it can't sleep, its busy doing other work, like rendering graphics.

You'll have to took at allegro source code why messages are not forwarded to you app. My wild guess is that it creates another window to handle input.

I'm not familiar with WM_LBUTTONDOWN, but couldn't you use Allegro's interrupt routines?

http://www.allegro.cc/manual/api/mouse-routines/mouse_callback

You'll need to keep track of the number of MOUSE_FLAG_LEFT_DOWNs you got, with a timer to see if they were sufficiently close together.
