15 // AeroTooltipManager | |
16 // | |
17 // Default Windows tooltips are broken when using our custom window frame | |
18 // - as soon as the tooltip receives a WM_MOUSEMOVE event, it starts spewing | |
19 // NCHITTEST messages at its parent window (us). These messages have random | |
20 // x/y coordinates and can't be ignored, as the DwmDefWindowProc uses | |
21 // NCHITTEST messages to determine how to highlight the caption buttons | |
22 // (the buttons then flicker as the hit tests sent by the user's mouse | |
23 // trigger different effects to those sent by the tooltip). | |
24 // | |
25 // So instead, we have to partially implement tooltips ourselves using | |
26 // TTF_TRACKed tooltips. | |
27 // | |
28 // TODO(glen): Resolve this with Microsoft. | |
