From 39e136e9b7666eb0dc9ad41c2cd50f7be87292df Mon Sep 17 00:00:00 2001 From: Chun-wei Fan Date: Tue, 2 Feb 2021 17:30:55 +0800 Subject: Gdk/Win32: Fix resizing surfaces This attempts to fix the counter-intuitive resizing of surfaces in GTK4 where the surface grows or shrinks at the right and/or bottom edge when the window resized from the top and/or left edge(s). This is not yet perfect as the window stutters upon resizing from the top and/or left edges, but at least makes resizing more intuitive. --- gdk/win32/gdksurface-win32.c | 58 +++++++++++++++++++++++++------------------- gdk/win32/gdksurface-win32.h | 1 + 2 files changed, 34 insertions(+), 25 deletions(-) diff --git a/gdk/win32/gdksurface-win32.c b/gdk/win32/gdksurface-win32.c index b9ec79e9ed..c690fed206 100644 --- a/gdk/win32/gdksurface-win32.c +++ b/gdk/win32/gdksurface-win32.c @@ -1633,42 +1633,48 @@ gdk_win32_surface_get_geometry (GdkSurface *window, RECT rect; GdkWin32Surface *impl = GDK_WIN32_SURFACE (window); - API_CALL (GetClientRect, (GDK_SURFACE_HWND (window), &rect)); - - POINT pt; + if (GDK_IS_TOPLEVEL (window) && impl->drag_move_resize_context.native_move_resize_pending) + rect = impl->next_layout.configured_rect; + else + { + POINT pt; GdkSurface *parent; - + if (GDK_IS_TOPLEVEL (window)) parent = NULL; else if (GDK_IS_POPUP (window)) parent = gdk_popup_get_parent (GDK_POPUP (window)); else parent = NULL; - - pt.x = rect.left; - pt.y = rect.top; - ClientToScreen (GDK_SURFACE_HWND (window), &pt); - if (parent) - ScreenToClient (GDK_SURFACE_HWND (parent), &pt); - rect.left = pt.x; - rect.top = pt.y; + API_CALL (GetClientRect, (GDK_SURFACE_HWND (window), &rect)); - pt.x = rect.right; - pt.y = rect.bottom; - ClientToScreen (GDK_SURFACE_HWND (window), &pt); + pt.x = rect.left; + pt.y = rect.top; + ClientToScreen (GDK_SURFACE_HWND (window), &pt); if (parent) - ScreenToClient (GDK_SURFACE_HWND (parent), &pt); - rect.right = pt.x; - rect.bottom = pt.y; + ScreenToClient (GDK_SURFACE_HWND (parent), &pt); - if (parent == NULL) - { - rect.left += _gdk_offset_x * impl->surface_scale; - rect.top += _gdk_offset_y * impl->surface_scale; - rect.right += _gdk_offset_x * impl->surface_scale; - rect.bottom += _gdk_offset_y * impl->surface_scale; - } + rect.left = pt.x; + rect.top = pt.y; + + pt.x = rect.right; + pt.y = rect.bottom; + ClientToScreen (GDK_SURFACE_HWND (window), &pt); + if (parent) + ScreenToClient (GDK_SURFACE_HWND (parent), &pt); + + rect.right = pt.x; + rect.bottom = pt.y; + + if (parent == NULL) + { + rect.left += _gdk_offset_x * impl->surface_scale; + rect.top += _gdk_offset_y * impl->surface_scale; + rect.right += _gdk_offset_x * impl->surface_scale; + rect.bottom += _gdk_offset_y * impl->surface_scale; + } + } if (x) *x = rect.left / impl->surface_scale; @@ -3947,6 +3953,8 @@ gdk_win32_surface_do_move_resize_drag (GdkSurface *window, impl->unscaled_width = new_rect.right - new_rect.left; impl->unscaled_height = new_rect.bottom - new_rect.top; + + impl->next_layout.configured_rect = new_rect; impl->next_layout.configured_width = (impl->unscaled_width + scale - 1) / scale; impl->next_layout.configured_height = (impl->unscaled_height + scale - 1) / scale; } diff --git a/gdk/win32/gdksurface-win32.h b/gdk/win32/gdksurface-win32.h index 7c937cd0fc..6be358338b 100644 --- a/gdk/win32/gdksurface-win32.h +++ b/gdk/win32/gdksurface-win32.h @@ -342,6 +342,7 @@ struct _GdkWin32Surface struct { int configured_width; int configured_height; + RECT configured_rect; } next_layout; #ifdef GDK_WIN32_ENABLE_EGL -- cgit v1.2.1
