## @package ParamFrame # Display of camera parameters, e.g. iso, white balance, record/standby, etc. # # @author Mark Zvilius # @date 10-Feb-2020 # @copyright Virtual Reality Technology Underwater Limited (VRTUL) # import sys import tkinter as tk from tkinter import ttk from tkinter import font ## # Create and run the tk-based UI. # # The root window fills the whole screen ("fullscreen" attribute). A frame is created # for the video display, but that is purely to reserve screen area for it. Omxplayer # does its own thing. # # With the "fullscreen" setting there is no title bar with a close icon to stop # the UI. To provide a way of exiting during testing, the Esc key and a mouse-click # will close the UI. # # @param root Root window # @return Parameter frame. # def run_ui(root): SCREEN_HEIGHT = 480 VIDEO_HEIGHT = 0 PARAMS_HEIGHT = SCREEN_HEIGHT - VIDEO_HEIGHT root.attributes('-fullscreen', True) root.configure(background='black') video_frame = ttk.Frame(master=root, width=568, height=VIDEO_HEIGHT) param_frame = ParamFrame(master=root, width=800, height=PARAMS_HEIGHT) ttk.Style().configure('TFrame', background='black') # video_frame.grid(row=0, column=0) param_frame.grid(row=0, column=0) root.bind('', lambda ev: root.destroy()) root.bind('', lambda ev: root.destroy()) return param_frame ## # Display of camera parameters, some of which can be modified by the user. # # Implemented within a ttk frame, using the Grid geometry manager. # Designed for 1920x540 area, assuming a 960x540 video window is using the top # half of the 1920x1080 screen. # # Example: # @code # root = tk.Tk() # param_display = ParamFrame(root, width=1920, height=540) # @endcode # class ParamFrame(ttk.Frame): ## # Constructor. # # @param self Object pointer. # @param master Containing window. # @param **kw Keyword arguments forwarded to ttk.Frame. # def __init__(self, master=None, **kw): super().__init__(master, **kw) self.grid_propagate(False) # use fixed size window specified by caller self.label_font = font.Font(family='DejaVu Sans', size=24) self.create_styles() self.create_widgets() self.layout() ## # Create styles used by widgets in the display. # # @param self Object pointer. # def create_styles(self): HIGHLIGHT_BACKGROUND = '#2020c0' s = ttk.Style() s.configure('TLabel', background='black', foreground='white', font=self.label_font) s.configure('Highlight.TLabel', background=HIGHLIGHT_BACKGROUND) s.configure('Standby.TLabel', background='green') s.configure('Recording.TLabel', background='red') s.configure('Error.TLabel', background='yellow', foreground='black') s.configure('NoError.TLabel') ## # Create widgets. # # @param self Object pointer. # def create_widgets(self): self.camera_label = ttk.Label(self) self.update_camera('--') self.wb_label = ttk.Label(self) self.update_wb('9999') self.shutter_label = ttk.Label(self) self.update_shutter('1/9999') self.fstop_label = ttk.Label(self) self.update_fstop('9.9') self.iso_label = ttk.Label(self) self.update_iso('99999') self.enc_label = ttk.Label(self) self.update_encoder('XxxXxx YYY ZZ') self.fps_label = ttk.Label(self) self.update_fps('99.77') self.status_label = ttk.Label(self, text='FOOBAR', style='Standby.TLabel') self.message_label = ttk.Label(self, text='foobar', style='Error.TLabel') # self.rectime_label = ttk.Label(self, text='99:59', style='Time.TLabel') # self.camtemp_label = ttk.Label(self, text='99 \N{DEGREE SIGN}C') ## # Lay out the widgets in the frame. # # @param self Object pointer. # def layout(self): # Padding for labels.
