I have a lot of data which are inside a GeUserArea sub class, the data is dynamic "lots of pointers, vectors of pointers, ..."

example:

class myNodeUserArea : public GeUserArea
{
private:
	std::vector<mNode*> nodes;
	std::vector<mWire*> wires;  
	....  
}

I'm not sure where to "put" these data so they can be saved/loaded easily, for example in the iCustomGui class, also I'm not sure how the TriState<> is loading and saving data

right now I can add my custom data type from userdata, display it with my custom gui, modify the user area stuff, once I change any thing in the ui the user area becomes empty!! "as if I just created it without any modification"

is called every time the layout gets changed "a nightmare!!" , 
so how can I store my data between draws, I see 2 examples which somehow stores a si_<_n_<_o_>__ data "tristate example for Niklas & custom slider example for Scotta"
  
not sure how and where is this TriState is holding the data "after all every Alloc create_<_o_<_o_<_o_<__<_o_<_o_>_ew class which should contain a fresh TriState, pretty confusing_<_o_<_o_>_p;:nauseated_face: "

Hello,

a GeUserArea and a custom GUI are exactly this – GUI elements that should display data but are not in charge of saving data.

You can store custom data in a custom datatype. To be sure that the data is correctly written, read and copied overwrite WriteData(), ReadData() and CopyData(). You could write your data to the Hyperfile using a BaseContainer and WriteContainer()[URL-REMOVED] (depending on your data).

The data is handed over to your custom GUI in SetData()[URL-REMOVED]. To get custom data simple read the value of the Tristate via GetValue()[URL-REMOVED] and then get the custom data type with GetCustomDataType()[URL-REMOVED]. When you change the data in your custom GUI you have to update the parent that the data was changed. This has to be done with a message:

  
BaseContainer m(BFM_ACTION);  
m.SetInt32(BFM_ACTION_ID, GetId());  
m.SetData(BFM_ACTION_VALUE, GeData(MYCUSTOMDATATYPE, data));  
SendParentMessage(m);

best wishes,
Sebastian

well I tested, kinda works but there is a missing part in the chain "tristate sets data, gets data, but data is reset or not saved"

    virtual Bool SetData(const TriState<GeData>& tristate) {
		GePrint("TriState SetData()");
		GePrint("setdata m_ua count " + String::IntToString(m_ua.count));
		
		const GeData& value = tristate.GetValue();
		if(!value.GetCustomDataType(23123123))
			return FALSE;
		iExampleDataType* mdata = static_cast<iExampleDataType*> (value.GetCustomDataType(23123123));
		m_ua.count = mdata->count;
		GePrint("setdata mdata count " + String::IntToString(mdata->count));
		
        return TRUE;
    }

    virtual TriState<GeData> GetData() {
		GePrint("TriState GetData()");
		Int32 count = m_ua.count;
		GePrint("getdata count " + String::IntToString(m_ua.count));
		iExampleDataType a;
		a.count = count;
		return TriState<GeData>(GeData(23123123, static_cast<CustomDataType> (a)));
    }

and here is the print of a simple variable "initialized to 1"

TriState GetData()
getdata count 2
msg count 2 #making sure that the msg is correct
TriState SetData()
setdata m_ua count 2
setdata mdata count 1 #bam!!! why it reads 1 not 2

Hello,

such a behavior could be caused by the absence or incorrect implementation of a function in your datatype class. For example it is also important to correctly implement the Compare()[URL-REMOVED] function.
