get_color

Show a color chooser dialog.

syntax:

get_color ?default?

example:

get_color "pick a colour" 15

panel

This is a bit more complex than the other methods but you can actually build simple customized interfaces that include things like file browsers, check boxes, drop down menus, etc.

syntax:
panel ?-w#? ?title? {{label var type args}...}

• ?-w#?: optional - use -w followed by a number to set the desired panel width in pixels

• ?title?: optional panel title the following arguments can be repeated as many times as needed

• label: this is the label of the following UI element

• var: this variable contains the default value and the result afetr the panel is closed

• args depend on the UI desired element:

  • f: a text line with folder button to enter an search filenames

  • f2: a text line with folder button to enter an search clips

  • m: multiline text input (about 4 lines)

  • m2: larger multiline input (8 lines)

  • n: notepad - huge text field. n can be followed by the number of lines required, i.e. n3

  • b: boolean check box

  • c: RGB color chip

  • e: enumeration pulldown, add tcl list of enumeration values

  • F: text font pulldown menu

  • x: expression input (needs some additinal variables)

  • (none): single line text input

example:
panel "load something" { {"the file: " input f} {"check something" checked b} }

display

Creates a window showing the result of command. The command is executed in the "context" of the given node, so this and a knob name in expressions refer to that node. In the window is an "update" button which causes the command to be run again.

syntax:

display ?-width #? ?-title text? command ?context-node?

• -w width: set the width of the window in pixels

• -t title: set the title of the window

• command: the text returned by this TCL command will be shown in the box

• node: if this node is changed, the dialog box will automatically update

examples:

display the IDs of all selected nodes
display -width 800 -title "what time is it?" selected_nodes

format the display a little bit and insert line breaks
display -width 800 -title "what time is it?" {join [selected_nodes] n}

The Best thing to do with the display command is to write an extra tcl proc that generates and formats the output in a way you want it and then have the display command call that proc..
