Containers

Containers are ways of grouping multiple widgets.

Containers can be nested within other containers to achieve complex layouts.

Container	Code/Description
	`tic_window(…)` Create a top level window
	`tic_col(A, B, C)` Layout objects in column
	`tic_row(A, B, C)` Layout objects rowwise
	`tic_frame(…)` Invisible container. Useful for advanced users who want to customize layout
	`tic_labelframe(…)` Frame with a a label and usually visible outline
	`tic_notebook(A, B, C)` Tabbed display
	`tic_panedwindow(A, B, C)` Layout multiple elements which can be resized as panes

Widgets

Widget	Code/Description
	`tic_label(…)` Display text. If you need headings rather than body text, Use `style = 'h1'` to `style = 'h5'` for different sized text
	`tic_button(…)` Clickable button. Available `style` options: ‘primary’, ‘seconary’, ‘info’, ‘success’, ‘warning’, ‘danger’, ‘light’, ‘dark’
	`tic_checkbutton(…)` On/off button (default styling)
	`tic_checkbutton(…)` On/off button with `style = 'toggle'`
	`tic_checkbutton(…)` On/off button with `style = 'switch'`
	`tic_radiobutton(…)` Groups of mutually exclusion options

	`popup_messagebox()`

Canvas

After creating a canvas with tic_canvas(), it can be manipulated with the following commands:

Draw on the canvas
- canvas_line()
- canvas_text()
- canvas_rect()
- canvas_polygon()
- canvas_oval()
- canvas_arc()
canvas_plot() render a plot to the canvas
canvas_clear() clear all objects from the canvas
canvas_image() render an image from a file to the canvas
canvas_save() save the contents of the canvas to an image file.

The actual canvas in tcl/tk renders structured graphics and it is much more like SVG or PDF than just a simple array of pixels.

The canvas implementation in this package treats the canvas as just a raster object i.e. a rectangular collection of pixels. This made it easier to write this package and keep the API/syntax simple, but it doesn’t unleash the full power of the canvas.

The effort to write a more complete abstraction over the canvas is not currently warranted. Please get in contact if such a facility is important to you.
