## set dialog

`set dialog pc fc bc oc th <numeric|n>`

Sets color properties for dialog box widgets.

`pc` prompt color
`fc` foreground text color
`bc` background color
`oc` outline color
`th` outline thickness
`n` numeric input only (optional)

### Usage Notes

1. If `th` is 1-5, a one-pixel border is drawn; if it is 6 or more, a two-pixel border is drawn.

2. Default colors are accessed by setting the colors to -1.

3. If the numeric option is invoked, keyboard inputs are restricted to 0-9, ., -, +, e, and E. Entered value is checked to assure it is a rational number of the form +/-nnnn, +/-nnnn.dddd, or +/-nnnn.ddddE+/-xxxx. This assures the returned numeric value is valid for use by a GrADS script.

4. See the `q dialog` refrence page for details on execution of the dialog box widgets.
