Tree controls

[spannerman]

Lindquist, Im aware that a question like "when is that for" is a bad one to ask, but roughly, roughly speaking, how far off is 0.5 from release?

I ask because Im wondering whether it would be worth while waiting for it, instead of working on code that may soon become deprecated.

[lindquist]

hopefully it will be out before christmas

Hi,

i just want to give some feddback.

I successful using your tree control on linux. ^^
It's working nice so far.
But on think i am missing.
There are no events for opening and closing of a tree node/item, right?
That would be nice to have, so tree items can dynamically added when opening a branch.

[DrPain]

Thanks for the feedback, madlion and martignasse.

At this point I'm not sure of the official future for this control. But I am using it, so I will keep developing it.
If others are using it (it seems there are), I'll keep posting updates here.

Anway, I added a couple of events for you madlion:
EventBranchOpened and EventBranchClosed.

I added event handlers for these events to the sample app so you can see how they work.

Also, I created a new WindowEventArgs based class for passing the arguments. Now in your event handler, you'll get the exact TreeItem that caused the event. See the sample for an example.

As always, let me know if you find any bugs or enhancements you'd like.

Cool, thanks a lot.

I will do an update and test it. ^^

Hey guys, do you know if the files in DrPain's latest zip file are compatible with the latest code of CEGUI? In other words, will this control work with CVS HEAD?

Ive given up on trying to create my own tree control...its just silly when theres a perfectly good working one out there already

[DrPain]

I updated to CVS just before submitting the first version, so it should be up to date.

[spannerman]

Ok, Ive just unzipped the last zip over my latest CVS CEGUI folder structre and rebuilt it all, but unfortunately it errors during the linking phase. Is there anything else I might need to do?

[DrPain]

Did you rebuild the library before building the sample app?
It looks like the tree control isn't linked into your CEGUI lib.

You're also missing timeGetTime() from the sample.
Are you on a Windows machine, or other OS? I wouldn't think it would be included in a non-Windows compile. I have a #define around it. However, winmm.lib should be set as an input lib in the project file for Windows.

I did a Rebuild All after getting the latest CEGUI code from CVS last night, all the projects built fine except for the tree demo.

How can you tell? What significance does this have, am I somehow using the wrong tree files?

Windows, using VC 7.1

Looking in the project settings for the tree demo, Winmm.lib is set as an additional dependency, but none of the other CEGUI samples have this. Whats this library for, and why does the tree demo need it but not the others?

I can tell because it's listed as an unresolved external. I can't see how you could be using the wrong files.
Is CEGUITreeItem.cpp listed in the project files under CEGUIBase/Source Files/elements?

I only use timeGetTime() to seed the rand function, which I used to randomize the tree layout at runtime. It could be taken out with no ill effect, I just like to do things properly (seeding rand before using it, that is).

If you comment out the following line from TreeDemoSample::initialiseSample(), that unresolved external should go away:
srand(timeGetTime());

If it is indeed listed as a dependency, it should be linked in. Very strange.

Do you get these same errors when building the Debug version?

[spannerman]

Yaay, its all working now

No, it certainly wasnt...none of the files were, including those in WidgetSets\Falagard. I really should have checked for this (doh!! ) but hey, the tree demo project was there in the solution so I just wrongly presumed it all was.

Following adding them in, I then got a timeGetTime error, so...

If you comment out the following line from TreeDemoSample::initialiseSample(), that unresolved external should go away:
srand(timeGetTime());

I commented that line out, and it compiled fine.
The final catch was renaming the TreeDemo.layout to TreeDemoVanilla.layout, and then it was all up and running.

Thanks for your help Dr Pain, and for this widget. Very cool indeed

[DrPain]

Doh! I just realised what happened.
I had included CEGUI.sln and Sample_TreeDemo.vcproj, but I forgot to include the new version of BaseSystem.vcproj, which would have all the base items.
I just zipped it up and posted it here (in case anyone else needs it): BaseSystem_2005-10-24.zip
Unzip this file to the directory cegui_mk2\makefiles\win32\VC++7.1\BaseSystem
Sorry for the trouble!

You're very welcome. I hope you get good use out of it.

Hey Crazy Eddie and the dev guys, will this tree control widget be making it into CVS by any chance?
