OptionTree problems [message #29725]

I am trying to use OptionTree. It appears that it should be able to manage the options internally. But if you call

OptionTree.Add( int parent, const char* text )

which should manage the Options internally,

it asserts when trying to access the (non-existent) option.

I also notice in the examples, there is a OptionTree example, and it uses external Options (because the internal options don't work?).

Am I doing something wrong? If not, is there anyone responsible for OptionTree?

Thanks,
avp

OptionTree requires external Options.

Hi mirek:

In the reference/TreeCtrl sample, I can not reproduce the icon display of optiontree mixed state.
I use upp_win_16800 version, and i have tested the Get(id) couldn't return the null state.

Hello mirek,

I think i found the reason.
In the CtrLib/Button.cpp Option& Option::Set(int b) function.
if the code is:

option = IsNull(b) ? Null : (bool)b;

then the option can't assign a Null.
but when changed to :

IsNull(b) ?  (option = Null) : (option = (bool)b);

the option can assigned to Null.
