Other Details

Here are some miscellaneous details about tknodesystem:

• Double clicking on the wire can remove the connection.
• Hovering over the node and pressing the <Delete> key removes the node and connected wires.
• Mouse scroll is used to zoom in/out.
• After connecting one socket, other sockets can be connected by just clicking over them. (No need to drag from the output socket again)
• Middle mouse button is used to drag all the components of the canvas.
• Using borderwidth>1 adds a border around the nodes.
• Using corner_radius=0 makes square shaped nodes.
• Using hover=False remove the hover effect from nodes.
• Multisided sockets can be used using multiside=True in the NodeOperation arguments.
• Multiple colors for sockets (in NodeOperation) can be defined using socket_color=[color_1, color_2, color_3, ...]
• Using grid_image=None removes the grid and makes a plain background with bg color.
• All the color values can be changed using .configure method.
• if your socket inputs take different datatypes, then add some hover info text using .config_socket(socket_num, hover_text).
• Clicking the <spacebar> in the canvas spawns the node menu.
• You can save the canvas file with any name but .json is preferred as the extension.
• The export file only contains the node arguments, node positions, socket numbers and the line numbers (on the basis of socket numbers).
• For now, lambda functions cannot be saved or loaded properly, so avoid using it in the commands of node (if you are planing to save them).
• The flow is always from output_socket-->input_socket(s), recursive connections are avoided.
