# wd commands 11!0

wd takes a string right argument and returns a string result. A wd argument is 0 or more statements delimited by semicolons. A statement is a command followed by 0 or more parameters. Commands and parameters are separated by one or more whitespace characters from the set: space, carriage return, line feed, and tab. Simple parameters start with an alphanumeric, -, or _, and run to a; or whitespace. A * starts a parameter at the next character, and runs to the end of the array. Delimited parameters start with " or 255{a. (EAV) and run to the matching delimiter. Some commands are not supported in some environments.
A wd error is a J domain error. Command qer returns the error message text and wd argument index for the last error.
The first letters of a command usually indicate a category: dde, mb (message box and common dialogs), menu, ole, p (parent), q (queries), set (setting properties), sm (session manager), and vbx.
A parameter can be an id, style, number, or text. An id identifies a parent, child, menu item, or other object. A style is a keyword, usually with a prefix. For example, bs_autoradiobutton is a button style.
A color is 3 parameters giving RGB values in the range 0 to 255. For example, 0 0 0 is black, 255 255 255 is white, and 255 0 0 is red.
A bool is 0 or 1 and is 1 if elided.

# wd Commands

beep [i] ; beep (parameter is ignored)
cc id class [style...] ; create child
clipcopy text ; put text on the clipboard
clippaste [type] ; result is text or files from the clipboard
0 - same as elided, clipboard text or empty if no text
1 - clipboard text or command failed if none
2 - clipboard files (drag and drop) or command failed if none
cn name ; set child name after a cc command (otherwise setcaption is preferred)
creategroup id ; causes parent commands to be ignored so that, when a form definition is run, the child controls created are in the current form. The id is a control in the current form, usually a tab control, and child creates are offset from that control. Controls created under creategroup are hidden and are part of a group with the id from their ignored pc command. The setshow command with a group id hides or shows the controls in a group. A form definition loaded under creategroup is a normal form definition that can be designed and tested with the form editor. It is loaded by a main form with a form_run that is bracketed by creategroup commands. The first creategroup gives the id of a control in the main form and the final creategroup command has no parameter and ends the group.
creategroup ; ends the group started by a previous creategroup command
dde commands...
fontdef fontspec; default font used when a child is created.
javalaf ; return list of supported Look and Feel settings
javasetlaf laf ; set Look and Feel from one of the lafs listed by the javalaf command. Existing windows are not repainted with the new laf. The Windows laf is only available on Windows.

mbcolor [colors] ; choose color common dialog box. Result is chosen color and 16 custom colors. Colors are 3 integers giving RGB values. Optional argument sets initial chosen color and 16 custom colors (51 integer values in range 0 to 255).
mbfont [fontspec] ; choose font common dialog. Start with last chosen and set new one if OK. Result is a fontspec.
mbopen title directory filename filterpairs [style...] ; open file common dialog returns fully qualified file name selected by user. Filterpairs are delimited by |. Styles are from the set (ofn_createprompt, ofn_filemustexist, ofn_nochangedir, ofn_overwriteprompt, ofn_pathmustexist).
wd 'mbopen'
wd 'mbopen mytitle "" "" "Write(*.wri)|*.wri|(Word(*.doc)|*.doc" ofn_filemustexist'
In Jwdw a filter can have multiple file types. For example:
"Text(*.txt);Html(*.htm)|*.txt;*.htm|(Word(*.doc)|*.doc"
mbprinter [pd_printsetup] ; The parameter selects the setup dialog instead of the print dialog. The result is '' if the user pressed CANCEL. If the user pressed OK, the result is the name of the selected printer followed by LF delimited values. Currently the only value after the name is the print-to-file value from the print dialog. This sets the session default printer setup ithat is used by glzcreate with no argument.
mbsave title directory filename filterpairs [style...] ; save file common dialog returns fully qualified file name (see mbopen).

setbkgnd id color ; (win32) set background RGB color of richedit or richeditm control
setcaption id text ; set control caption. If control is ownerdraw button, text is picture filename.
setcolor id textR G B textbkgndR G B bkgndR G B ; set control colors. You can set form and control (text, text background, and background) colors. The setcolor command can override the gray readonly edit boxes. The setcolor command has no effect on push buttons or the dropdown listbox of a combobox (unfortunate Window facts). The textbkgndR G B values are ignored in Java and generally look bad in Windows if different from the bkgndR G B values. For example:
abc_run=: 3 : 0
wd ABC
NB. initialize form here
wd 'pcolor 0 0 255'
wd 'setcolor cceditm 255 0 0 0 0 255 0 0 255'

setselect id [parameters...] ; set selection

> edit, editm, richedit, richeditm - parameters are [ start end [noscroll ] ]. Selects text from start to end. If start and end are elided, then all text is selected. If noscroll is elided or 1, then the selection is not scrolled into view. If noscroll is 0, then the selection is scrolled into view
> combobox, listbox - -number of item to select. -1 clears selection.
> trackbar - parameters are start and end of range to mark as selected

setshow id [bool] ; show (1) or hide. If it is a group id (the id of the pc command ignored by a creategroup), then all controls in the group are affected. Controls explicitly hidden are not affected by a group show.

setupdate id ; Update window immediately. Noop in Java.
setxywh id x y w h ; set child position and size in units
setxywhx id x y w h ; set child position and size in pixels

smkeywords n keywords ; code editor keywords (for color n). No effect in Jwdp.
smsetlog ; set input log
tbar filename [count style] ; set filename of bmp file (bmp or gif for jwdp) for toolbar. If style is tbstyle_flat then count is the number of toolbar positions (buttons and seperators). The count and tbstyle_flat parameters are ignored in Jwdp. The file contains images that are 16 pixels wide by 15 pixels high.
tbarset id index image; set id for a toolbar button. index is the position in the displayed toolbar and image is the index of the button bitmap to use from the toolbar bitmap.
tbarshow [bool]; show (1) or hide toolbar
timer i ; set interval timer to i milliseconds. Event systimer occurs when time has elapsed. The timer keeps triggering events until the timer is turned off. An argument of 0 turns the timer off. The systimer event may be delayed if J is busy, and it is possible for several delayed events to be reported as a single event.
tnomsgs [bool] ; (win32) 1 disables GUI msg processing (such as mouse events and ctrl-break) while the J engine is running and 0 enables.
wait ; (win32) the normal message loop executes a handler in immediate execution when an event occurs. This is overkill for getting input from a simple form, and the way mb works is simpler: the message box is displayed, other events are disabled until it is closed, and the result is the wd result. The wait command allows a form to be used in a similar way. The wait command shows the form, disables events except for that form, and waits for an event. The event information is given by wd'q'. While a wait form is active events in other forms, DDE events, and timer events are disabled. They are enabled when the wait form is closed.
winexec text [style]; Execute program. style is same as for pshow.
wd ' winexec "write.exe text.wri" sw_showmaximized;'
xywh x y w h ; sets rectangle. -1 value inherits the previous value.

> wd 'ddedis s t;' conversation with server s on topic t

ddeex s t d ; data d is sent to server s for topic t to execute
ddename id ; set dde service name (can be done only once). Command line /ddename= can also set dde service name.
ddepoke s t i d ; send data to S|T!I
ddereq s t i ; data for item i is requested from S|T
ddereqd d ; send data in response to ddereq event (must be done immediately after ddereq event)
ddestart s t i ; advise loop requested for S|T!I. New data signals ddeadvise event.
ddestop s t i ; stop advise loop on S|T!I

# ole commands (win32)

oledlg id ; run property dialog. State can be saved with the olesave command.
oleenable id eventname [bool] ; enable/disable event. You must enable an event in order to trigger an event in J.
oleget id objectname property ; return property value. Objectname is base, temp, or a name set with oleid. If the result is an object, it is set as the temp object. This allows a series of wd commands that use the temp object to get the next object.
olegetlic ; returns licence information
oleid ; give a temp object a name to make it permanent
oleinfo id ; return information about events, methods, properties, and constants
oleload id filename ; initialize properties from a file created by olesave. An oleload should only be done once before it is shown.
olemethod id objectname method parameters....; run a method. , is an elided parameter. A wd parameter of , is the same as "", except it is treated as an elided parameter where appropriate.Some methods distinguish between a numeric parameter and a string. A simple (not delimited) string that is an integer is treated as an integer. If you want 23 to be treated as a string, use "23". If the result is an object, it is set as the temp object.
An object parameter is indicated by a simple parameter of the form:object:formid.childid.objectname
A picture object parameter is indicated by a simple parameter of the form:picture:filename
olemethodx ;
oleocx ;
olerelease ;
olesave id filename ; save properties in a file that can be used to initialize a control after it is created
oleset id objectname property value ; set property value
olesetlic ; set the licence information for a runtime OCX
