I seek for help if anybody cares:

This is pIcon from the Add function

[kiu]

What about loading the icon as 32x32 and then modify its size using Image conversions and capturing with GDI+?
Maybe it's possible to do it in this way
Anyway as I have a little more time I'll try to search how to do it with PhiLho's API

I suggested it cause I'm trying to find a way to show menu icons also from image files, but I'm relatively new to DllCall, so...

well.... that is not the good way. Icon will be very distorted. If there are other sizes its best to use them.

Hi majkinetor,

I tried your MMenu on a small example for test purposes. I want the menu to show me the number of folders and files in two directories. But since that process takes some time I wanted the user to see the counting with alive update of the menu. But it doesn't seem to work. What am I doing wrong here?
Sometimes the menu doesn't react or is only have displayed.

Could you please advice a solution?

I was doing something similar and will post it soon.
FolderMenu that I created load arbitrary folder into the menu. If you call menu while it is in building process you can see first item of the menu being the word "---- IN PROGRESS ---- ". It continues to build menu in the background though, so next time you call it, it will show full menu, or again "in progress" with more items.

I think that dynamic adding of menu items can not be done now with real time update, but I really don't know for sure, as i didn't experiment much with this, it seemd like not important. You can change existing items which is demonstrated with time in the test example. One possible quick solution would be to first add all items as separators, like, if you have 100 files in the folder, you add 100 separators. Then you iterate trought menu using ID's and remove "s" option, change the name to the name of the file, change the icon to the icon of the file. Be aware that this introduces some small bug that happens when you first define all items in the menu without icons, then add icons (some trailin title letters will be cut of). For that, you must add at least 1 icon at the beginning. You can add icon to the separator to fix this, put the same handle for all separator icons. The point to note here that separator in MMenu is dynamic, you can turn any item into separator and vice-versa.

I will post here FolderMenu when I update it to use newest MMenu API as I did it after first API version was completed and didn't find time to update it yet. You can use it to show/create menu like this:

It seems when there is a timer running (even with SetBatchLines, 100ms) a while longer the menu isn't responding. I tried to start the timer oustide the OnInit function and the same happend.

Using timers with MMenu isn't good idea, I must documente that. I use it only to postpone execution some number of milliseconds, like for Tooltip example.

Always runnig timer will interfere with MMenu handlers. This is actually hack of AHK, provided to me by Chris. You know that script is blocked when AHK menu is shown, and it continues after user closes the menu. In MMenu, it is not blocked but I let the script go using some info Chris told me, so you are able to process handlers. Keep in mind that although MMenu is very entusiasticaly desgined there are still lot of AHK limitations that forbid it to do some things like a charm. This kind of thing can be 100% successifully done only natively, using C. You shouldn't put MMenu in very stresfull situations, like doing bunch of things in the background while it is displayed, using timers, etc.... The other things that prevents to create and delete menus all the time without losing performance will be fixed in next update.

From your reply I see that you didn't look at my code. Not a problem.

I thought as well that it might be problematic to add item dynamically. That's why I added them with a "x" and gave them names. And during the counting I change the text of the items. But why isn't this working. It works in GUIs. Is there someting in the code that prevents these updates?

Edit: I didn't use the timer constantly. I only use it to create a new thread.

Thanks a lot. Much appreciated. Have fun surfing. I hope your exames were successful.

well, it works here

I see number of files counting

Documents executes in 1 sec and I can barely see it counting, but Program Files executes for minutes and I see counting all the time. The only problematic thing here is that you can't exit Program Files menu while it is counting or use it at all but I guess Thread, NoTimers somewhere in the MMenu code may fix that.

[majkinetor]

Ok, this is rather inventive way, and it seems it doesn't block the menu

[toralf]

Thanks for the help,

I managed to do it with the extra timer (break loop and start form that position again. Not very nice or effective, but the menu is responding again. If you find a better solution, please let me know.

Good, I am glad.

I hope you are aware its not MMenu problem at all. What you did is typical mistake which is not trivial to fix. Real solution is about splitting GUI and working procedure into 2 threads, and to call working procedure ASYNCRHONIOSLY. The message queue is in non working thread and GUI can respond normaly to messages while procedure is looping something. Procedure after that informs mother thread that it is finished via callbacks. This is not trivial even in dotNet which has very nice thread support. I know lot about this as I had this problem number of times.

As you see, this must be handled by specific design of scripts in AHK, as it doesn't support multithreading ( .... ) (callbacks are not so mandatory). I will try to see why sleep in loop doesn't work, as it would make ideal solution.
