Don't Receive WMHI_CHANGEWINDOW

[tygre]

Hi there!

I'm yet again stumped

I create this ClassAct window and listen to some of its properties: while I can receive WMHI_CLOSEWINDOW or WMHI_VANILLAKEY, I never receive WMHI_CHANGEWINDOW or WMHI_MOUSEMOVE.

I looked at many examples, including on Thomas' and Peter's Web sites, no luck... I must be missing something obvious in the definition of my window or when listening to the events?

Here are some essential (?) parts of my code:

	win_object = NewObject(
		WINDOW_GetClass(),  NULL,
		WA_ScreenTitle,     version_get_version(),
		WA_Title,           "AmiModRadio",
		WA_Left,            prefs_get_main_window_X(),
		WA_Top,             prefs_get_main_window_Y(),
		WA_DepthGadget,     TRUE,
		WA_DragBar,         TRUE,
		WA_CloseGadget,     TRUE,
		WA_Activate,        TRUE,
		WA_SmartRefresh,    TRUE,
		WA_IDCMP,           IDCMP_CHANGEWINDOW | IDCMP_MOUSEMOVE | IDCMP_VANILLAKEY,
		WINDOW_ParentGroup, lay_object,
		TAG_END);

...

	GetAttr(
		WINDOW_SigMask,
		_object->window_object,
		&window_signals);

...

		signals = Wait(SIGBREAKF_CTRL_C |
					   ...
					   window_signals);

...

		if((signals & window_signals) == window_signals)
		{
			while((signalsResult = CA_HandleInput(_object->window_object, NULL)) != WMHI_LASTMSG)
			{
				switch(signalsResult & WMHI_CLASSMASK)
				{
				case WMHI_CLOSEWINDOW:
					is_closing = TRUE;
					break;

				case WMHI_VANILLAKEY:
					printf("WMHI_VANILLAKEY\n");
					break;

				case WMHI_MOUSEMOVE:
					printf("WMHI_MOUSEMOVE\n");
					break;

				case WMHI_CHANGEWINDOW:
					printf("WMHI_CHANGEWINDOW\n");
					_prefs_save_position();
					break;

...

Thanks in advance!

Thanks in advance!

maybe you have to add the wanted events here:

WA_IDCMP,           IDCMP_CHANGEWINDOW | IDCMP_MOUSEMOVE | IDCMP_VANILLAKEY | WMHI_CHANGEWINDOW | WMHI_WHAT_EVA | ...,

Hi Bebbo!

Thanks for your help! I tried your suggestion but I still don't receive these events

Besides, I thought that WA_IDCMP only takes IDCMP flags and that ClassAct "magically" translates these, like for VANILLAKEY: I specify IDCMP_VANILLAKEY but receive WMHI_VANILLAKEY.

What really confuses me is that the couple IDCMP_VANILLAKEY/WMHI_VANILLAKEY works but not the couple IDCMP_CHANGEWINDOW/WMHI_CHANGEWINDOW

Cheers!

The code in your fragment looks OK. It looks like you are using an ancient ClassAct version? It could be a bug in window.class that has since been fixed (certainly there were plenty of those!), so I would suggest upgrading to OS3.2 which has a much better implementation of window.class.

The suggestion to add WMHI_#? flags to WA_IDCMP is wrong; Intuition is not going to know what to do with them.

Hi Minuous!

Thanks for your help! You put the finger exactly where my problem was: I was using ClassAct v2 instead of the latest v3.3.

Since I installed v3.3, WA_IDCMP, IDCMP_CHANGEWINDOW produces WMHI_CHANGEWINDOW as expected!

Cheers!

[Minuous]

Glad it helped. ClassAct 3.3 is 25 years old though so it is the "latest" version only in the sense that soon afterwards the name was changed to ReAction and development continued under that name.

Hi Minuous!

I know! In our Amiga parallel universe, time works differently

I heard and read about ReAction but I'm confused about where/how to get it: AmigaSystem was telling me that it's in OS v3.9 and I think that it's also in v3.2... but can I get if for v3.1 independently? And what about its SDK?

Cheers!

[Minuous]

ReAction is not available separately, it has been integrated into AmigaOS. Older versions of it are in OS3.5 and OS3.9, the latest version is in OS3.2(.2).

The SDK for ReAction is part of the Amiga NDK, which is freely available, eg. from https://www.hyperion-entertainment.c...=form&file=126

[thomas]

ClassAct is available for free, the SDK is shareware.

ReAction is only available for users paying for new OS versions. The SDK is free.

It's a good strategy to develop on 3.1 with ClassAct. Programs will continue to work with ReAction, but you also reach users running 3.1.

[tygre]

Hi Minuous and Thomas!

Thanks for your answers

I bought v3.2 but I want AmiModRadio to work on 3.1 so I'll stick to ClassAct for now... Maybe I'll add a ReAction UI later to benefit from new classes!

Cheers!
