PF_Cmd_UPDATE_PARAMS_UI is not triggered

[yaroslavr32391224]

Dear AE fellows,

I create hidden parameters and want them to be unhidden when the user changes the parameters in the UI.

(Specifically, for reference, I want a N parameters SKELETON_ANGLE to appear when the input text has N letters. The user input text is introduced via the PF_Param_BUTTON with the help of javascript text input window and AEGP_ExecuteScript )

From the supervisor example I deduce that one needs to handle PF_Cmd_UPDATE_PARAMS_UI event.

Now the question. 

How to trigger PF_Cmd_UPDATE_PARAMS_UI when the user changes the text input in my plugin?

I store user text input in sequence_data and implement all the functions: sequence_setup, resetup and flatten. Therefore the plugin actually knows that the input changes. And I see with my naked eyes that the plugin prints my input onscreen)

But PF_Cmd_UPDATE_PARAMS_UI is not triggered.

1.

I thought of adding PF_STATE to my sequence_data struct and then added 

		ERR(suites.ParamUtilsSuite3()->PF_GetCurrentState(in_data->effect_ref,
			SKELETON_BUTTON,
			NULL,
			NULL,
			&unflatSequenceDataP->state));

at the end of sequence_data_setup (and resetup)

in hope that the changed state of button parameter will trigger the PF_Cmd_UPDATE_PARAMS_UI event.

But alas, this didn't work.

2. I also tried to add the relevant code into PF_Cmd_USER_CHANGED_PARAM handling, like this:

		PF_ParamDef		param_copy[17];
		ERR(MakeParamCopy(params, param_copy));
     	if (text_input.length() != 0) {
		        param_copy[SKELETON_ANGLE].param_type = PF_Param_ANGLE;
				param_copy[SKELETON_ANGLE].ui_flags &= ~PF_PUI_INVISIBLE;
				ERR(suites.ParamUtilsSuite3()->PF_UpdateParamUI(in_data->effect_ref,
					SKELETON_ANGLE, &param_copy[SKELETON_ANGLE]));

				// Changing visibility of params in AE is handled through stream suites
				ERR(suites.PFInterfaceSuite1()->AEGP_GetNewEffectForEffect(globP->my_id, in_data->effect_ref, &meH));
				ERR(suites.StreamSuite2()->AEGP_GetNewEffectStreamByIndex(globP->my_id, meH, SKELETON_ANGLE, &angle_streamH));
				// Toggle visibility of parameters
				ERR(suites.DynamicStreamSuite2()->AEGP_SetDynamicStreamFlag(angle_streamH, AEGP_DynStreamFlag_HIDDEN, FALSE, hide_themB));
				// Change popup menu items
				ERR(suites.EffectSuite3()->AEGP_GetEffectParamUnionByIndex(globP->my_id, meH, ANGLE_ID, &param_type, &param_union));

				if (meH) {
					ERR(suites.EffectSuite2()->AEGP_DisposeEffect(meH));
				}
				if (angle_streamH) {
					ERR(suites.StreamSuite2()->AEGP_DisposeStream(angle_streamH));
				}

		}
		else {
						hide_themB = TRUE;
			param_copy[SKELETON_ANGLE].param_type = PF_Param_ANGLE;
			param_copy[SKELETON_ANGLE].ui_flags |= PF_PUI_INVISIBLE;
			ERR(suites.ParamUtilsSuite3()->PF_UpdateParamUI(in_data->effect_ref,
				SKELETON_ANGLE, &param_copy[SKELETON_ANGLE]));

			// Changing visibility of params in AE is handled through stream suites
			ERR(suites.PFInterfaceSuite1()->AEGP_GetNewEffectForEffect(globP->my_id, in_data->effect_ref, &meH));
			ERR(suites.StreamSuite2()->AEGP_GetNewEffectStreamByIndex(globP->my_id, meH, SKELETON_ANGLE, &angle_streamH));
			// Toggle visibility of parameters
			ERR(suites.DynamicStreamSuite2()->AEGP_SetDynamicStreamFlag(angle_streamH, AEGP_DynStreamFlag_HIDDEN, FALSE, hide_themB));
			// Change popup menu items
			//ERR(suites.EffectSuite3()->AEGP_GetEffectParamUnionByIndex(globP->my_id, meH, ANGLE_ID, &param_type, &param_union));

			if (meH) {
				ERR(suites.EffectSuite2()->AEGP_DisposeEffect(meH));
			}
			if (angle_streamH) {
				ERR(suites.StreamSuite2()->AEGP_DisposeStream(angle_streamH));
			}
		}

And then I added the additional outfalg PF_OutFlag_REFRESH_UI at the end of my parameter changing function:

out_data->out_flags = out_data->out_flags | PF_OutFlag_FORCE_RERENDER | PF_OutFlag_REFRESH_UI;

It worked (but I suppose this is not the regular way to implement such things).

  However I have an unusual behavior. My parameter SKELETON_ANGLE is introduced inside some  PARAM_TOPIC in the paramsSetup function with the flag: 

def.flags = PF_ParamFlag_START_COLLAPSED;

However, when this parameter becomes unhidden, the whole PARAM_TOPIC is switched into uncollapsed state. How can I force the parameter to become unhidden but to keep it inside collapsed topic?

let's go theough the basics first.

did you set PF_OutFlag_SEND_UPDATE_PARAMS_UI on global setup?

did you set PF_ParamFlag_SUPERVISE on the param you wish to supervise?

Genius lives in simple things.

Thanks, Shachar!

I added PF_OutFlag_SEND_UPDATE_PARAMS_UI and all things started to work like a charm!
