From d35a19f9d3722468dc2bb4ec7449a0cee07b3b8c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Karel=20Ko=C4=8D=C3=AD?= Date: Tue, 23 Jan 2018 15:36:48 +0100 Subject: Better layout registers This does dynamic layout of registers. This implemntation is just terrible. It works but it's almost unreadable. It's just too much code for such a small feature. But I can't be bothered to refactor it on top of hacking it. --- qtmips_gui/qtmips_gui.pro | 6 +- qtmips_gui/registersdock.cpp | 21 ++-- qtmips_gui/registersdock.h | 4 +- qtmips_gui/statictable.cpp | 255 +++++++++++++++++++++++++++++++++++++++++++ qtmips_gui/statictable.h | 64 +++++++++++ 5 files changed, 335 insertions(+), 15 deletions(-) create mode 100644 qtmips_gui/statictable.cpp create mode 100644 qtmips_gui/statictable.h (limited to 'qtmips_gui') diff --git a/qtmips_gui/qtmips_gui.pro b/qtmips_gui/qtmips_gui.pro index 4767fe9..4b13d4c 100644 --- a/qtmips_gui/qtmips_gui.pro +++ b/qtmips_gui/qtmips_gui.pro @@ -33,7 +33,8 @@ SOURCES += \ coreview/constant.cpp \ coreview/junction.cpp \ coreview/logicblock.cpp \ - coreview/and.cpp + coreview/and.cpp \ + statictable.cpp HEADERS += \ mainwindow.h \ @@ -55,7 +56,8 @@ HEADERS += \ coreview/constant.h \ coreview/junction.h \ coreview/logicblock.h \ - coreview/and.h + coreview/and.h \ + statictable.h FORMS += \ NewDialog.ui \ diff --git a/qtmips_gui/registersdock.cpp b/qtmips_gui/registersdock.cpp index 809b692..d9d3f2f 100644 --- a/qtmips_gui/registersdock.cpp +++ b/qtmips_gui/registersdock.cpp @@ -37,23 +37,23 @@ static const QString labels[] = { RegistersDock::RegistersDock(QWidget *parent) : QDockWidget(parent) { scrollarea = new QScrollArea(this);
