From 66bbf336c6af7353ef0aeed58002c46543b30635 Mon Sep 17 00:00:00 2001 From: rubidium Date: Tue, 2 Jan 2007 19:19:48 +0000 Subject: (svn r7759) -Merge: makefile rewrite. This merge features: - A proper ./configure, so everything needs to be configured only once, not for every make. - Usage of makedepend when available. This greatly reduces the time needed for generating the dependencies. - A generator for all project files. There is a single file with sources, which is used to generate Makefiles and the project files for MSVC. - Proper support for OSX universal binaries. - Object files for non-MSVC compiles are also placed in separate directories, making is faster to switch between debug and release compiles and it does not touch the directory with the source files. - Functionality to make a bundle of all needed files for for example a nightly or distribution of a binary with all needed GRFs and language files. Note: as this merge moves almost all files, it is recommended to make a backup of your working copy before updating your working copy. --- window.c | 2000 -------------------------------------------------------------- 1 file changed, 2000 deletions(-) delete mode 100644 window.c (limited to 'window.c') diff --git a/window.c b/window.c deleted file mode 100644 index 1a12c7c6b..000000000 --- a/window.c +++ /dev/null @@ -1,2000 +0,0 @@ -/* $Id$ */ - -#include "stdafx.h" -#include -#include "openttd.h" -#include "debug.h" -#include "functions.h" -#include "map.h" -#include "player.h" -#include "window.h" -#include "gfx.h" -#include "viewport.h" -#include "console.h" -#include "variables.h" -#include "table/sprites.h" -#include "genworld.h" - -// delta between mouse cursor and upper left corner of dragged window -static Point _drag_delta; - -static Window _windows[25]; -Window *_z_windows[lengthof(_windows)]; -Window **_last_z_window; ///< always points to the next free space in the z-array - -void CDECL SetWindowWidgetsDisabledState(Window *w, bool disab_stat, int widgets, ...) -{ - va_list wdg_list; - - va_start(wdg_list, widgets); - - while (widgets != WIDGET_LIST_END) { - SetWindowWidgetDisabledState(w, widgets, disab_stat); - widgets = va_arg(wdg_list, int); - } - - va_end(wdg_list); -} - -void CDECL SetWindowWidgetsHiddenState(Window *w, bool hidden_stat, int widgets, ...) -{ - va_list wdg_list; - - va_start(wdg_list, widgets); - - while (widgets != WIDGET_LIST_END) { - SetWindowWidgetHiddenState(w, widgets, hidden_stat); - widgets = va_arg(wdg_list, int); - } - - va_end(wdg_list); -} - -void CDECL SetWindowWidgetsLoweredState(Window *w, bool lowered_stat, int widgets, ...) -{ - va_list wdg_list; - - va_start(wdg_list, widgets); - - while (widgets != WIDGET_LIST_END) { - SetWindowWidgetLoweredState(w, widgets, lowered_stat); - widgets = va_arg(wdg_list, int); - } - - va_end(wdg_list); -} - -void RaiseWindowButtons(Window *w) -{ - uint i; - - for (i = 0; i < w->widget_count; i++) { - if (IsWindowWidgetLowered(w, i)) { - RaiseWindowWidget(w, i); - InvalidateWidget(w, i); - } - } -} - -void HandleButtonClick(Window *w, byte widget) -{ - LowerWindowWidget(w, widget); - w->flags4 |= 5 << WF_TIMEOUT_SHL; - InvalidateWidget(w, widget); -} - - -static void StartWindowDrag(Window *w); -static void StartWindowSizing(Window *w); - -static void DispatchLeftClickEvent(Window *w, int x, int y) -{ - WindowEvent e; - const Widget *wi; - - e.we.click.pt.x = x; - e.we.click.pt.y = y; - e.event = WE_CLICK; - - if (w->desc_flags & WDF_DEF_WIDGET) { - e.we.click.widget = GetWidgetFromPos(w, x, y); - if (e.we.click.widget < 0) return; /* exit if clicked outside of widgets */ - - /* don't allow any interaction if the button has been disabled */ - if (IsWindowWidgetDisabled(w, e.we.click.widget)) return; - - wi = &w->widget[e.we.click.widget]; - - if (wi->type & WWB_MASK) { - /* special widget handling for buttons*/ - switch (wi->type) { - case WWT_PANEL | WWB_PUSHBUTTON: /* WWT_PUSHBTN */ - case WWT_IMGBTN | WWB_PUSHBUTTON: /* WWT_PUSHIMGBTN */ - case WWT_TEXTBTN | WWB_PUSHBUTTON: /* WWT_PUSHTXTBTN */ - HandleButtonClick(w, e.we.click.widget); - break; - } - } else if (wi->type == WWT_SCROLLBAR || wi->type == WWT_SCROLL2BAR || wi->type == WWT_HSCROLLBAR) { - ScrollbarClickHandler(w, wi, e.we.click.pt.x, e.we.click.pt.y); - } - - if (w->desc_flags & WDF_STD_BTN) { - if (e.we.click.widget == 0) { /* 'X' */ - DeleteWindow(w); - return; - } - - if (e.we.click.widget == 1) { /* 'Title bar' */ - StartWindowDrag(w); - return; - } - } - - if (w->desc_flags & WDF_RESIZABLE && wi->type == WWT_RESIZEBOX) { - StartWindowSizing(w); - InvalidateWidget(w, e.we.click.widget); - return; - } - - if (w->desc_flags & WDF_STICKY_BUTTON && wi->type == WWT_STICKYBOX) { - w->flags4 ^= WF_STICKY; - InvalidateWidget(w, e.we.click.widget); - return; - } - } - - w->wndproc(w, &e); -} - -static void DispatchRightClickEvent(Window *w, int x, int y) -{ - WindowEvent e; - - /* default tooltips handler?
