[SOLVED] DG Message when palette dialog is docked?

[Erenford]

Hello,
Is there a DG Message in callback when a palette dialog is docked? Or know when docking location changes/what the docked location is?

What I want to do is to re-arrange my dialog items whenever the dialog is docked according to its docked location.

For ex. I have a palette with 2 list box: if I docked it on top, it will look like the 2nd screen. If I docked it on left/right, instead of the one in the 3rd screen it'll move the 2nd list box and put it at the bottom of the 1st list box, taking less space than if I didn't re-arrange it.

Is this possible?

Dear ArchiCAD-Talk forum members,

today I implemented a "new API function" just for you:

ACAPI_Notify_CatchDockStateChanged
With this function you can catch dock/undock events and docked title orientation changed events also.

Interface:

typedef struct { 
	short	dialId; 
	bool	isDocked; 
	bool	isDockedTitleHorizontal; 
} API_DockStateInfo; 
 
typedef void	__ACENV_CALL	APIDockStateChangedCallBackProc (short dialId, API_DockStateInfo dockStateInfo); 
 
void	ACAPI_Notify_CatchDockStateChanged (short dialId, APIDockStateChangedCallBackProc *callBackProc);

Implementation:

void	ACAPI_Notify_CatchDockStateChanged (short dialId, APIDockStateChangedCallBackProc *callBackProc) 
{ 
	if (DGGetDialogType (dialId) == DG_DT_PALETTE) { 
		static GS::HashTable<short, API_DockStateInfo> dockStateInfos; 
		API_DockStateInfo actDockStateInfo; 
		actDockStateInfo.dialId = dialId; 
 
		GS::Guid paletteGuid; 
		DGGetPaletteGuid (dialId, &paletteGuid); 
 
		actDockStateInfo.isDocked = DGIsPaletteDocked (paletteGuid); 
 
		short hFrameSize; 
		short vFrameSize; 
		short hClientSize; 
		short vClientSize; 
		DGGetDialogSize (ACAPI_GetOwnResModule (), dialId, DG_ORIGFRAME, &hFrameSize, &vFrameSize); 
		DGGetDialogSize (ACAPI_GetOwnResModule (), dialId, DG_ORIGCLIENT, &hClientSize, &vClientSize); 
		actDockStateInfo.isDockedTitleHorizontal = (hFrameSize - hClientSize > vFrameSize - vClientSize); 
 
		API_DockStateInfo prevDockStateInfo; 
		if (!dockStateInfos.Get (dialId, &prevDockStateInfo)									|| 
			prevDockStateInfo.isDocked					!= actDockStateInfo.isDocked				||  
			prevDockStateInfo.isDockedTitleHorizontal	!= actDockStateInfo.isDockedTitleHorizontal) 
		{ 
			dockStateInfos.Put (dialId, actDockStateInfo); 
			callBackProc (dialId, actDockStateInfo); 
		} 
	} 
}

Example:

void	__ACENV_CALL DockStateChangedCallBack (short dialId, API_DockStateInfo dockStateInfo) 
{ 
	char buffer[512]; 
	sprintf (buffer, "DockStateChanged: dialId=%d, isDocked=%d, isDockedTitleHorizontal=%d", dialId, dockStateInfo.isDocked, dockStateInfo.isDockedTitleHorizontal); 
	ACAPI_WriteReport (buffer, true); 
	// Handle dock state changed event as you want! 
} 
 
// -------------------------------------- With C++ style Palette: ----------------------------------------------------- 
 
// Define the following function in the dialog's observer class: 
		virtual void PanelIdle (const DG::PanelIdleEvent&); 
 
// ------------------------------- 
 
void	MyDialogObserver:PanelIdle (const DG::PanelIdleEvent& /*ev*/) 
{ 
	ACAPI_Notify_CatchDockStateChanged (myDialog->GetId (), DockStateChangedCallBack); 
	// myDialog is a pointer to the dialog 
} 
 
// ---------------------------------------- With C style Palette: ----------------------------------------------------- 
 
// In the dialog's callback function: 
//		at the end of DG_MSG_INIT message handling: 
			DGEnableMessage (dialID, DG_ALL_ITEMS, DG_MSG_NULL); 
			break; 
		case DG_MSG_NULL: 
			ACAPI_Notify_CatchDockStateChanged (dialID, DockStateChangedCallBack); 
			break;

Feel free to use this and please report me here if you have any problem about this function!

Tibor
