Palette re-opens automatically on changing views

dushyant — Mon, 06 Dec 2021 06:52:43 GMT

Hi,

I used DG::Palette for an addon and observed it auto re-opens after being closed, when I change to certain views. These are the steps to reproduce the scenario:

Open the palette (from the user addon menu)
Close the palette (using the close [x] button at the top-right corner)
Open the Profile Manager palette and click 'Edit'
Close the profile editing window.
The addon palette reappears.

This can be tested with the example addon DG_Test > OwnerDrawnListBoxPalette

This however does not happen with the 'Favorites' palette, for example. I want the addon palette to behave like that.

Anyone any idea?

Thanks.

Some additional flagging is missing from the palette (DG_Test/OwnerDrawnListBoxPalette) code. The palette state should be stored before the palette temporarily goes to/comes back from hidden state due to window switching.

A static bool variable can be used to temporarily store the visibility state (paletteOpenAtClose):

GSErrCode __ACENV_CALL OwnerDrawnListBoxPalette::PaletteAPIControlCallBack (Int32 referenceID, API_PaletteMessageID messageID, GS::IntPtr param) { static bool paletteOpenAtClose = false; GSErrCode err = NoError; if (referenceID == OwnerDrawnListBoxPalette::ODLBPaletteRefId ()) { OwnerDrawnListBoxPalette& palette = OwnerDrawnListBoxPalette::GetInstance(); switch (messageID) { case APIPalMsg_ClosePalette: case APIPalMsg_HidePalette_Begin: if (palette.IsVisible()) { paletteOpenAtClose = true; palette.Hide(); } else { paletteOpenAtClose = false; } break; case APIPalMsg_OpenPalette: paletteOpenAtClose = true; // no break case APIPalMsg_HidePalette_End: if (paletteOpenAtClose && !palette.IsVisible()) { palette.Show (); } break; case APIPalMsg_DisableItems_Begin: palette.DisableItems(); break; case APIPalMsg_DisableItems_End: palette.EnableItems(); break; case APIPalMsg_IsPaletteVisible: (*reinterpret_cast<bool*> (param)) = palette.IsVisible(); break; default: break; } } return err; }
