From f237f998d1168139d599c550d54169cd8f94052d Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Mon, 25 Jan 2021 18:43:19 +0000 Subject: [PATCH] gdb/tui: remove special handling of locator/status window The locator window, or status window as it is sometimes called is handled differently to all the other windows. The reason for this is that the class representing this window (tui_locator_window) does two jobs, first this class represents a window just like any other that has space on the screen and fills the space with content. The second job is that this class serves as a storage area to hold information about the current location that the TUI windows represent, so the class has members like 'addr' and 'line_no', for example which are used within this class, and others when they want to know which line/address the TUI windows should be showing to the user. Because of this dual purpose we must always have an instance of the tui_locator_window so that there is somewhere to store this location information. The result of this is that the locator window must never be deleted like other windows, which results in some special case code. In this patch I propose splitting the two roles of the tui_locator_window class. The tui_locator_window class will retain just its window drawing parts, and will be treated just like any other window. This should allow all special case code for this window to be deleted. The other role, that of tracking the current tui location will be moved into a new class (tui_location_tracker), of which there will be a single global instance. All of the places where we previously use the locator window to get location information will now be updated to get this from the tui_location_tracker. There should be no user visible changes after this commit. gdb/ChangeLog: * Makefile.in (SUBDIR_TUI_SRCS): Add tui/tui-location.c.
