andrej@1574:
andrej@1574: EnhancedStatusBar Is A Slight Modification (Actually A Subclassing) Of wx.StatusBar.
andrej@1574: It Allows You To Add Almost Any Widget You Like To The wx.StatusBar Of Your Main
andrej@1574: Frame Application And Also To Layout Them Properly.
andrej@1574:
andrej@1574:
andrej@1574: What It Can Do:
andrej@1574:
andrej@1574: 1) Almost All The Functionalities Of wx.StatusBar Are Still Present;
andrej@1574: 2) You Can Add Different Kind Of Widgets Into Every Field Of The EnhancedStatusBar;
andrej@1574: 3) The AddWidget() Methods Accepts 2 Layout Inputs:
andrej@1574: - horizontalalignment: This Specify The Horizontal Alignment For Your Widget,
andrej@1574: And Can Be ESB_EXACT_FIT, ESB_ALIGN_CENTER_HORIZONTAL, ESB_ALIGN_LEFT And
andrej@1574: ESB_ALIGN_RIGHT;
andrej@1574: - varticalalignment: This Specify The Vertical Alignment For Your Widget,
andrej@1574: And Can Be ESB_EXACT_FIT, ESB_ALIGN_CENTER_VERTICAL, ESB_ALIGN_BOTTOM And
andrej@1574: ESB_ALIGN_LEFT;
andrej@1574:
andrej@1574: EnhancedStatusBar Is Freeware And Distributed Under The wxPython License.
