event sequence question?
« on: September 03, 2011, 02:44:49 pm »
By reading the CC's source, I'm totally confused about the events sent from the C::B core and the event sequences.

I'd like to see the official development document about all the C::B's event sending sequence and other official C::B event.

I remember several years ago, we have a discussion: Puzzling cbEVT_EDITOR_* event behavior

But that discussion does not show all the sequence, so are there any documents?

If I can remember, jens has a plugin to monitor all the event sent from the core, so is it possible share/add this plugin to the contributed plugin achieve, so that we can learn more about C::B, and maybe it is much better for plugin developers.

Thanks.
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

No, of course, the source is the only documentation, because it is the most up to date resource
and it is too easy if there are docs, real programmers don't write docs and don't need docs :)  (the last one is me joking)
(most of the time I ignore long posts)
[strangers don't send me private messages, I'll ignore them; post a topic in the forum, but first read the rules!]

There are two of this plugins - Jens's was called EventsDisplay (IIRC). However, adding this to trunk makes no sense as it would seriously spoil down C::B in terms of performance and stability. Just search the forums (it should be still there) and compile it yourself... it's a pretty simple plugin in the end. (However, I doubt it is still up-to-date...?!)

I just updated it, and will upload it to my server.
It might also be added to the plugins (not contrib), just like the headerguard-plugin for example, without being included in automake-system and contrib-plugins workspace.

I just updated it, and will upload it to my server.

Here it is:
http://apt.jenslody.de/downloads/DisplayEvents_0.3.7z
unpack it into src/plugins subdirectory of C::B's sources (not in contrib !!).
Don't forget to run src/update[.bat] afterwards, to copy the plugin from devel- to output-folder.

The Makefile.am is not tested, so it might or might not work after integrating it into automake-system.

Thank you for the sharing! I will try it now.
I currently work on Windows, so I don't need automake-system. :D

This plugin works fine on Windows.

I'm testing on the trunk code( I also remove the codecompletion.dll and debuger.dll when testing), the strange thing is after I recieved a cbEVT_EDITOR_TOOLTIP event, if I hit the ctrl key, then I do not receive the cbEVT_EDITOR_TOOLTIP_CANCEL event. This indicates that something we have done in debugger branch (change the scintilla related dwell code to filter the ctrl) should reconsidered. :D


BTW:
Please remove the *.so file in the package: http://apt.jenslody.de/downloads/DisplayEvents_0.3.7z
It is Linux only file.

Hi, Jens, this plugin (DisplayEvents plugin - CodeBlocks)has a build error when building against trunk code(rev9765).
Those three events do not exist in SDK, so they should be removed.
Code: [Select]
cbEVT_EDITOR_BREAKPOINT_ADD
cbEVT_EDITOR_BREAKPOINT_EDIT
cbEVT_EDITOR_BREAKPOINT_DELETE

Also, I just open a sample project (which created by a wx wizard), and I receive those logs, I don't know why there are so many cbEVT_EDITOR_ACTIVATED events. Before open the project, I have only C::B startup-home-page opened, after opening the project, two editors are opened.

Code: [Select]

21:24:23,421  =>  cbEVT_PROJECT_OPEN

21:24:23,421  =>  cbEVT_PROJECT_ACTIVATE

21:24:27,000  =>  cbEVT_EDITOR_TOOLTIP_CANCEL
21:24:28,218  =>  cbEVT_EDITOR_TOOLTIP
21:24:32,078  =>  cbEVT_EDITOR_TOOLTIP_CANCEL
21:24:33,250  =>  cbEVT_EDITOR_TOOLTIP
21:24:33,609  =>  cbEVT_EDITOR_TOOLTIP_CANCEL

Any one can help to explain why four cbEVT_EDITOR_ACTIVATED happens. The strange thing is this cbEVT_EDITOR_ACTIVATED is always following after cbEVT_EDITOR_SWITCHED event.

Especially, why there are two cbEVT_EDITOR_ACTIVATED events after
Code: [Select]
21:24:23,375  =>  cbEVT_EDITOR_OPEN
Project data set for E:\code\cb\test_code\wx3-hang\wx3_hangApp.cpp

PS: I'm hunting a CC deadlock bug...

Hi,

I added/updated project files, removed obsolete events and add new ones from sdk_events.h (svn11494). You can download from attachment.

Note: I tested only cbDisplayEvents_wx31_64.cbp and did NOT touch cbDisplayEvents-unix.cbp.

Hi, Quiss, many thanks.
Can you put those source code in a more "safe" place instead of an attachment of a forum post. I mean the attachment maybe cleaned up by forum administrators, maybe a good place is put the source in github.com or sourceforge.net, then post the link here. Thank you!
