From bb6721549b30c33b0080975aa19a0b02a916c7e5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bert=20M=C3=BCnnich?= Date: Mon, 28 Jul 2014 20:36:32 +0200 Subject: Overhauled window drawing, yet again; fixes issue #155 - Buffer for window content is bigger than the window, minimizes artifacts when window is resized - Back to using XSetWindowBackgroundPixmap() instead of XCopyArea(), no need to handle exposure events; X server can show gray background directly after resize event before sxiv redraws the window contents --- Makefile | 2 +- image.c | 2 +- main.c | 12 ++++------ thumbs.c | 20 ++++++++-------- window.c | 83 ++++++++++++++++++++++++---------------------------------------- window.h | 10 ++++---- 6 files changed, 54 insertions(+), 75 deletions(-) diff --git a/Makefile b/Makefile index 190caf8..3350679 100644 --- a/Makefile +++ b/Makefile @@ -1,4 +1,4 @@ -VERSION = git-20140725 +VERSION = git-20140728 PREFIX = /usr/local MANPREFIX = $(PREFIX)/share/man diff --git a/image.c b/image.c index d24cdd2..8f14461 100644 --- a/image.c +++ b/image.c @@ -497,7 +497,7 @@ void img_render(img_t *img) imlib_context_set_image(img->im);
