FKEY(<value>)

See also FKEY (Disambiguation)

The FKey internal function is similar to CmdKey, but returns more information, particularly about how a field is exited. A HotKey is very similar to either of these, but is different in that hotkey is not a control word, statement, nor internal function. HotKey is simply a term that refers to an assigned FKey value. Hot key (Fkey) values can be assigned via a print fields or input fields statement that makes a control clickable. Fkey values can also be assigned to entire windows to make the window trigger an interrupt when it is clicked.

Additionally, when an Input Field is assigned an Fkey value and Enter is pressed while the cursor is in that field, or the field is double clicked, then that fkey number is assigned to the internal FKEY variable and, if that value is preset to take action, then that interrupt occurs. OPTION 48 causes BR to disregard Fkey value assignments when Enter is pressed (FKEY is set to zero).

The following table shows a comparison of the values that are returned by FKey and CmdKey when a particular key is pressed to terminate field input. Fkey values above 100 do not cause INPUT FIELDS to terminate processing, but when control is returned to a program for other reasons the FKEY internal function can be used to determine what was keyed.

FKey(X) sets the value of FKey to X. It also sets the value of CmdKey. However, if X is greater than 91 then CmdKey is set to zero. Likewise, the function CmdKey(X) sets both CmdKey and FKey to the value of X.

Note that BR retains select (hilite) status while shift or control remain depressed after a program receives control in navigation mode. When in edit mode, the control key temporarily switches to navigation mode.

*In the following chart, the asterisks denotes a change that occurred with version 4.3. Most of the keys in prior versions were unassigned, but a few were assigned differently.

FKey 200 and FKey 206 are similar. On windows machines with single click enabled a 200 will be returned instead of a 206.

These have been tested and should probably be added to the the chart above.

201 Double Click (sometimes - also 200) (Requires Option (config) 52)
206 Click

From a GRID with LX attributes

FKey value Cause Additional
124 Mouse Wheel scroll up
125 Mouse Wheel scroll down

From a TextBox with AEX attributes

These have been tested and should probably be added the the chart above. FKey values listed in the GRID with AEX section above are not duplicated here.

FKey value Cause Additional
102 Up
103 Left (from leftmost position)
104 Down

From a GRID with L attributes

FKey value Cause Additional
105 Attempt to Scroll past top
106 Attempt to Scroll past bottom

KStat Only

The KSTAT$ internal function will return a few additional FKey values which Input Fields and Input Select will not. These FKeys are as follows:

FKey Description
176 Click
177 Second Click in Double Click
180 Right Click
181 Second Click in Double Right Click

Combobox Only

Combo Boxes that contain the x attribute often return FKey 209 in such cases use curfld(curfld,fkey) to avoid blinking.

 00010 do
 00020    rinput #win,fields mat io$,attr '[A]': mat setting$,choice_policy$,choice_desc$
 00030    if fkey=209 then let curfld(curfld,fkey)
 00040 loop until fkey<>209

Hot Windows

For versions 4.2 and higher FKEY= may now be specified in an Open Window statement. This makes the window hot, so a user can click anywhere in the window to tell the program that they want to switch focus. The FKEY value is then inheritable, but not to independent windows. In other words, assigning an FKEY value to a window automatically assigns the same FKEY value to it's child windows, unless another FKEY ( or -1 ) is assigned to a child.
