XbaeInput(3x) XbaeInput(3x) NAME XbaeInput - The Input widget class. SYNOPSIS #include <Xbae/Input.h> DESCRIPTION XbaeInput is a text input field that provides generic customised data entry and formatting for strings. It does this by using a clever XmNmodifyVeri- fyCallback that is installed when the XmNpattern resource is set. The XmN- pattern value may include optional characters and literals which will be discussed later in this document. The XbaeInput widget is ideal for restricting data input to a digit, al- phanumeric character or an alphabetic character. If XmNconvertCase is set, the widget automatically changes an inserted character to uppercase or low- ercase. Literal characters can also be included in the XmNpattern that can be automatically inserted as the user types by setting the XmNautofill re- source to True. Optional literals cannot be auto inserted, however. Unlike the XmText field from which this widget is subclassed, the toggle- overwrite action is bound to the osfInsert key. The XmNoverwriteMode is also provided to allow the resource to be changed programatically. When the XbaeInput widget loses focus or is activated in the same way as the XmText field would be, callbacks on the XmNvalidateCallback list are invoked, allowing the programmer to validate the data as well as reformat- ting the existing string. Classes XbaeInput inherits behavior and resources from the Core, XmPrimitive, and XmText widget classes. The class pointer is xbaeInputWidgetClass. The class name is XbaeInput. New Resources The following table lists the new resources defined by XbaeInput. The codes in the Access column indicate whether the given resource can be set at creation time (C), or set by using XtSetValues (S), or retrieved by us- ing XtGetValues (G). +-----------------------------------------------------------------------------+ | XbaeInput Resource Set | +--------------------+------------+-------------+---------------------+-------+ | Name |Class Type Default |Access | +--------------------+------------+-------------+---------------------+-------+ | XmNalignment |XmCAlignmentunsigned char XmALIGNMENT_BEGINNING |CSG | +--------------------+------------+-------------+---------------------+-------+ | XmNautoFill |XmCBoolean Boolean False |CSG | +--------------------+------------+-------------+---------------------+-------+ | XmNconvertCase |XmCBoolean Boolean True |CSG | +--------------------+------------+-------------+---------------------+-------+ | XmNoverwriteMode |XmCBoolean Boolean False |CSG | +--------------------+------------+-------------+---------------------+-------+ | XmNpattern |XmCString String NULL |CSG | +--------------------+------------+-------------+---------------------+-------+ | XmNvalidateCallback|XmCCallback Callback NULL |CSG | +--------------------+------------+-------------+---------------------+-------+ This resource has not been implemented. XmNalignment This resource has not been implemented! Specifies the alignment of the text when being edited and displayed. Possible values are XmALIGNMENT_BEGINNINGand XmALIGNMENT_END. If Xm- Nalignment is set to XmALIGNMENT_END, the text will be right justi- fied. If left as the default of XmALIGNMENT_BEGINNING, the text will be left justified. XmNautoFill The XmNautoFill resource, when set to True, attempts to automatically insert a literal if a non literal is hit in an allowed literal posi- tion. For example, if the XmNpattern resource was set up to accept a date in dd/mm/yyyy format and the user typed "18041999" The resulting string would appear as "18/04/1999". The default value is False, where the user would have to type the literal. XmNconvertCase Tells the XbaeInput widget what should be done to alphabetic charac- ters if the requires a lowercase or uppercase letter. If the XmNcon- vertCase is set to True (default), then the character is automatically converted to the correct case. If set to False, then the user must type the character in the correct case in order for it to be accepted. See the EXAMPLE PATTERNS section towards the end of this document for some examples. overwriteMode Whether the widget accepts characters in insert mode or overwrite mode is controlled by the resource. Setting this resource calls the XmText toggle-overwrite() action routine, so the Motif toolkit being used must also support this routine. XmNpattern The XmNpattern resource specifies what can be typed into the XbaeInput widget. If set to the default value of NULL any character may be en- tered. The XmNpattern can be set to a string containing the following characters. a alphabetic characters only b both - either digit or character c any character at all d digits only U upperchase character only L lowercase character only [ start of optional sequence ] end of optional sequence \\ escapes the next character | next char is an alternative to previous. May be chained. Inherited Resources The following table lists the resources which XbaeInput inherits from it's superclasses XmText, XmPrimitive and Core. For a complete description of each resource, refer to the man page for that superclass. The codes in the "Access" column indicate whether the given resource can be set at creation time (C), or set by using XtSetValues (S), or retrieved by using XtGetVal- ues (G).

+------------------------------+----------------------------+-------------+-------------------+------+ Callback Information XmNvalidateCallback Callbacks on the XmNvalidateCallback list are called when the edits to the XbaeInput widget are activated or a losing focus event occurs. Each callback function is passed the following structure: typedef struct { int reason; XEvent *event; String pattern; String value; Boolean doit; } XbaeInputValidateCallbackStruct; reason Set to XmCR_ACTIVATE if the user caused the callback to be invoked by activating the changes in the cell or XmCR_LOS- ING_FOCUS if the callback was called due to a losing focus event. event The event pointer that triggered the callback. pattern A pointer to the pattern for the XbaeInput widget or NULL if one does not exist. This value is provided as a convenience to the callback. value The value as it appears in the cell at the time of the call- back being invoked. doit Indicates whether or not the value is valid. By setting doit to False the value will not be accepted. This callback provides the application of checking the validity of the value entered into the XbaeInput widget. Checking the validity of a date may be one such instance. If the value is verified as valid, all values of the callback may be left unchanged. If the pointer to the value is changed, the new value will be displayed in the cell and storage for the old value deallocated by the XbaeInput widget. The new value's memory is owned by the application and it is up to the ap- plication to use XtFree to deallocate it. If the value is not considered valid, the doit flag should be set to False, forcing the user to make changes before the value can be ac- cepted. Translations XbaeInput inherits translations from XmText. Some versions of Motif do not have the :<Key>osfInsert: toggle-overstrike() translation installed by default. If this is the case, XbaeInput automati- cally registers this translation. Type Converters XbaeInput does not define any new type converters other than the standard type converters registered by Xt and Motif. Public Functions The following external entry points to XbaeInput class methods are defined: XbaeCreateInput() Widget XbaeCreateInput() Widget parent; String name; ArgList arglist; Cardinal argcount; parent Specifies the parent widget ID. name Specifies the name of the created widget arglist Specifies the argument list argcount Specifies the number of attribute/value pairs in the argu- ment list (arglist) XbaeCreateInput() creates an instance of an XbaeInput widget and re- turns the associated widget ID. EXAMPLE PATTERNS d[d]/d[d]/dd[dd] A date that would accept 1/1/99, 12/1/99, 1/12/1999, 01/01/2000, etc. U[L][L][L][L][L], U[L][L][L][L][L] "Surname, Firstname" combination, automatically forcing correct case and allowing between 1 and 6 characters per name. UU-dd[d][d] A flight number consisting of two uppercase letters and 2 to 4 numbers (ddd) ddd-dddd An American style phone number UdU[-]dUd A Canadian postcode with optional dash. Virtual Bindings The bindings for virtual keys are vendor specific. For information about bindings for virtual buttons and keys, see VirtualBindings(3X).
