From 18bb55545e6f99e9ab80900db65222e8b98aee13 Mon Sep 17 00:00:00 2001 From: Albrecht Schlosser Date: Mon, 6 Mar 2017 16:54:33 +0000 Subject: Fl_Tabs: improve tab label drawing (STR #3075, STR #3076). New method Fl_Tabs::tab_align() supports icons in tabs (STR #3076). This commit also enables drawing labels of Fl_Window children (STR #3075). Setting tab_align(FL_IMAGE_NEXT_TO_TEXT) draws images (icons) in the tab labels if the child has an image(). Currently this draws the image() even if the child is deactived (so it should presumably draw the deimage()). Todo: Label measurement and Fl_Windows as children still need fixups. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12185 ea41ed52-d2ee-0310-a9c1-e6b18d33e121 --- FL/Fl_Tabs.H | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'FL') diff --git a/FL/Fl_Tabs.H b/FL/Fl_Tabs.H index 3d75db81d..06c23aee5 100644 --- a/FL/Fl_Tabs.H +++ b/FL/Fl_Tabs.H @@ -208,6 +208,7 @@ class FL_EXPORT Fl_Tabs : public Fl_Group { int tab_height(); void draw_tab(int x1, int x2, int W, int H, Fl_Widget* o, int sel=0); protected: + Fl_Align tab_align_; // tab label alignment void redraw_tabs(); void draw(); @@ -231,6 +232,24 @@ public: Fl_Widget *which(int event_x, int event_y); ~Fl_Tabs(); void client_area(int &rx, int &ry, int &rw, int &rh, int tabh=0); + /** + Sets the tab label alignment. + + The default is FL_ALIGN_CENTER so tab labels are centered, but since + the label space is measured (per label) to fit the labels, there + wouldn't be any difference if labels were aligned left or right. + + If you want to show an image (icon) next to the group's label you can + set a different label alignment.
