From c29b4b5e16e87199846a0f97bc3bd2d80b6c0c07 Mon Sep 17 00:00:00 2001 From: Matthias Melcher Date: Thu, 26 Aug 2004 22:24:24 +0000 Subject: FLTK1.1 Quartz support: - added a 'test/unittests' which wil check for identical drawing on all platforms. This was desperatly needed to fix tremendous problems in getting the Quartz drawing routines right - disabled anti-aliasing for functions that draw straight lines at integer coordinates git-svn-id: file:///fltk/svn/fltk/branches/branch-1.1@3788 ea41ed52-d2ee-0310-a9c1-e6b18d33e121 --- test/Makefile | 8 ++- test/unittests.cxx | 208 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 214 insertions(+), 2 deletions(-) create mode 100644 test/unittests.cxx (limited to 'test') diff --git a/test/Makefile b/test/Makefile index 8e85bd3b2..3c7d74bb4 100644 --- a/test/Makefile +++ b/test/Makefile @@ -1,5 +1,5 @@ # -# "$Id: Makefile,v 1.19.2.7.2.41 2004/04/11 04:39:00 easysw Exp $" +# "$Id: Makefile,v 1.19.2.7.2.42 2004/08/26 22:24:24 matthiaswm Exp $" # # Test/example program makefile for the Fast Light Tool Kit (FLTK). # @@ -26,6 +26,7 @@ include ../makeinclude CPPFILES =\ + unittests.cxx \ adjuster.cxx \ arc.cxx \ ask.cxx \ @@ -89,6 +90,7 @@ CPPFILES =\ valuators.cxx ALL = \ + unittests$(EXEEXT) \ adjuster$(EXEEXT) \ arc$(EXEEXT) \ ask$(EXEEXT) \ @@ -181,6 +183,8 @@ uninstall: $(ALL): ../lib/$(LIBNAME) # General demos... +unittests$(EXEEXT): unittests.o + adjuster$(EXEEXT): adjuster.o arc$(EXEEXT): arc.o @@ -372,5 +376,5 @@ shape$(EXEEXT): shape.o # -# End of "$Id: Makefile,v 1.19.2.7.2.41 2004/04/11 04:39:00 easysw Exp $". +# End of "$Id: Makefile,v 1.19.2.7.2.42 2004/08/26 22:24:24 matthiaswm Exp $". # diff --git a/test/unittests.cxx b/test/unittests.cxx new file mode 100644 index 000000000..2ea086a67 --- /dev/null +++ b/test/unittests.cxx @@ -0,0 +1,208 @@ + + + + +#include +#include +#include +#include +#include +#include + +Fl_Window *win = 0; + +int point_test_ix, line_test_ix, rect_test_ix, viewport_test_ix; + +void changePageCB(Fl_Widget*, void *ixvp) { + int ix = (int)ixvp; + int i = 0, n = win->children(); + for ( ; ichild(i)->hide(); + if (ix>=n || ix<0) ix = n-1; + win->child(ix)->show(); +} + +void newButton(int x, int y, int w, int h, const char *l, int ix, const char *tt) { + Fl_Button *b = new Fl_Button(x, y, w, h, l); + b->tooltip(tt); + b->callback(changePageCB, (void*)ix); +} + +void createMenuPage() { + Fl_Group *page, *g; + page = new Fl_Group(0, 0, 600, 600); + g = new Fl_Group(100, 20, 460, 26, "drawing:"); + g->align(FL_ALIGN_LEFT); + newButton(100+2, 22, 22, 22, "1", point_test_ix, "Testing pixel drawing"); + newButton(125+2, 22, 22, 22, "2", line_test_ix, "Testing fl_line"); + newButton(150+2, 22, 22, 22, "3", rect_test_ix, "Testing fl_rect"); + newButton(175+2, 22, 22, 22, "4", viewport_test_ix, "Testing viewport alignment"); + g->end(); + page->end(); +} + +Fl_Group *beginTestPage(const char *l) { + int ix = win->children(); + Fl_Group *g = new Fl_Group(0, 0, win->w(), win->h()); + g->box(FL_FLAT_BOX); + g->hide(); + newButton(20, 20, 20, 20, "M", -1, "Return to main menu"); + newButton(20, 40, 20, 20, "@<", ix-1, "previous test"); + newButton(20, 60, 20, 20, "@>", ix+1, "next test"); + Fl_Box *bx = new Fl_Box(60, 20, win->w()-80, 100, l); + bx->box(FL_THIN_DOWN_BOX); + bx->align(FL_ALIGN_INSIDE|FL_ALIGN_WRAP); + return g; +} + +//------- test the point drawing capabilities of this implementation ---------- +class PointTest : Fl_Widget { +public: PointTest(int x, int y, int w, int h) : Fl_Widget(x, y, w, h) {} + void draw() { + int a = x(), b = y(); + fl_color(FL_BLACK); + fl_rect(x(), y(), w(), h()); + fl_point(a+10, b+10); fl_point(a+20, b+20); + fl_point(a+10, b+20); fl_point(a+20, b+10); + fl_color(FL_RED); a = x()+70; + fl_point(a+10, b+10); fl_point(a+20, b+20); + fl_point(a+10, b+20); fl_point(a+20, b+10); + fl_color(FL_GREEN); a = x(); b = y()+70; + fl_point(a+10, b+10); fl_point(a+20, b+20); + fl_point(a+10, b+20); fl_point(a+20, b+10); + fl_color(FL_BLUE); a = x()+70; + fl_point(a+10, b+10); fl_point(a+20, b+20); + fl_point(a+10, b+20); fl_point(a+20, b+10); + } +}; +void fl_point_test() { + point_test_ix = win->children(); + Fl_Group *page = beginTestPage( + "testing the fl_point call\n" + "You should see four pixels each in black, red, green and blue.
