Common Dialog Boxes

Windows provides several built-in dialog boxes called Common Dialog Boxes that perform useful functions.

The color dialog box allows selection of colors. The result is a list of the RGB values for 17 colors, of which the first is chosen in the standard color dialog box, and the rest in the custom color dialog box. Try:

   _3[\ ". wd 'mbcolor'

This returns a matrix of the 17 values, one row per color.

The font dialog box allows selection of a logical font. The result describes the font chosen (in this case the font used in the J logo):

   wd 'mbfont'
"Bookman Old Style" 24

The message box dialog box displays a message and waits for a user response. For example:

   wd 'mb title text'
   wd 'mb title text mb_iconstop mb_retrycancel'

To list all message box styles:

   list wd 'qs mb'
mb_abortretryignore mb_defbutton2       mb_defbutton3 
mb_iconasterisk     mb_iconexclamation  mb_iconhand   
mb_iconinformation  mb_iconquestion     mb_iconstop   
mb_ok               mb_okcancel         mb_retrycancel
mb_yesno            mb_yesnocancel

The open filename dialog box allows the user to select a fully qualified file name:

   wd 'mbopen'
   wd 'mbopen title "" "" Write(*.wri)|*.wri| Word(*.doc) |*.doc"
ofn_filemustexist'

To list all open filename styles:

   list wd 'qs mbopen'
ofn_createprompt    ofn_filemustexist...
ofn_overwriteprompt ofn_pathmustexist

The save filename dialog box is similar to the open filename dialog box:

   wd 'mbsave'
