From 4046a892ee5d8e7ac3b3a4e42d8692e878dceb7f Mon Sep 17 00:00:00 2001 From: Mathijs van de Nes Date: Wed, 23 Sep 2015 13:11:00 +0200 Subject: Fix Window.set_inner_size() on Win32 Previously, the function would actually set the outer size of the window instead of the inner size. We fix this by first letting windows calculate the outer size based upon the specified inner size. --- src/api/win32/mod.rs | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) (limited to 'src/api/win32') diff --git a/src/api/win32/mod.rs b/src/api/win32/mod.rs index f580950..59fdf5d 100644 --- a/src/api/win32/mod.rs +++ b/src/api/win32/mod.rs @@ -182,8 +182,17 @@ impl Window { use libc; unsafe { - user32::SetWindowPos(self.window.0, ptr::null_mut(), 0, 0, x as libc::c_int, - y as libc::c_int, winapi::SWP_NOZORDER | winapi::SWP_NOREPOSITION | winapi::SWP_NOMOVE); + // Calculate the outer size based upon the specified inner size + let mut rect = winapi::RECT { top: 0, left: 0, bottom: y as winapi::LONG, right: x as winapi::LONG }; + let dw_style = user32::GetWindowLongA(self.window.0, winapi::GWL_STYLE) as winapi::DWORD; + let b_menu = !user32::GetMenu(self.window.0).is_null() as winapi::BOOL; + let dw_style_ex = user32::GetWindowLongA(self.window.0, winapi::GWL_EXSTYLE) as winapi::DWORD; + user32::AdjustWindowRectEx(&mut rect, dw_style, b_menu, dw_style_ex); + let outer_x = (rect.right - rect.left).abs() as libc::c_int; + let outer_y = (rect.top - rect.bottom).abs() as libc::c_int; + + user32::SetWindowPos(self.window.0, ptr::null_mut(), 0, 0, outer_x, outer_y, + winapi::SWP_NOZORDER | winapi::SWP_NOREPOSITION | winapi::SWP_NOMOVE); user32::UpdateWindow(self.window.0); } } -- cgit v1.2.3
