Defines a mask that will filter interactive text input.
Set to NULL to remove the mask.
Since the validation process is performed key by key when the user is typing, an intermediate value cannot be typed if it does not follow the mask rules.
If you set the VALUE attribute any text can be used. To set a value that is validated by the current MASK use VALUEMASKED.
|IUP_MASK_UINT||"/d+"||unsigned integer number|
|IUP_MASK_FLOAT||"[+/-]?(/d+/.?/d*|/./d+)"||floating point number|
|IUP_MASK_UFLOAT||"(/d+/.?/d*|/./d+)"||unsigned floating point number|
|IUP_MASK_EFLOAT||"[+/-]?(/d+/.?/d*|/./d+)([eE][+/-]?/d+)?"||floating point number with exponential notation|
|IUP_MASK_FLOATCOMMA||"[+/-]?(/d+/,?/d*|/,/d+)"||floating point number|
|IUP_MASK_UFLOATCOMMA||"(/d+/,?/d*|/,/d+)"||unsigned floating point number|
If YES, will turn the filter case insensitive. Default: NO.
If YES, value can NOT be NULL or empty. Default: NO (can be empty or NULL).
The decimal symbol for string/float conversion. Can be "." or ",". Must be set before MASKFLOAT.
Defines an integer mask with limits. Format: "%d:%d" ("min:max"). It will replace MASK using one of the pre-defined masks.
Defines a floating point mask with limits. Format: "%g:%g" ("min:max"). It will replace MASK using one of the pre-defined masks.
MASKFAIL_CB: Action generated when the new text fails at the mask check. (since 3.9)
int function(Ihandle *ih, char *new_value); [in C]
elem:maskfail(new_value: string) -> (ret: number) [in Lua]
identifier of the element that activated the
new_value: Represents the new text value.
The pattern to be searched in the text can be defined by the rules given below.
|c||Matches a "c" (non-special) character|
|.||Matches any single character|
|[abc]||Matches an "a", "b" or "c" characters|

|[^a-dg]||Matches any character which is neither between "a" and "d" nor "a" "g"|
|/d||Matches any digit (just like [0-9])|
|/D||Matches any non-digit (just like [^0-9])|
|/l||Matches any letter (just like [a-zA-Z])|
|/L||Matches any non-letter (just like [^a-zA-Z])|
|/w||Matches any alphanumeric character (just like [0-9a-zA-Z ])|
|/W||Matches any non-alphanumeric character (just like [^0-9a-zA-Z ])|
|/s||Matches any "blank" character (TAB, SPACE, CR)|
|/S||Matches any non-blank character|
|/n||Matches a newline character|
|/t||Matches a tabulation character|

|/xnn||Matches an ASCII character with a nn value (hexadecimal)|
|/special||Matches the special character literally (/[, //, /.)|
|abc||Matches a sequence of a, b and c patterns in order|
|aj bj c||Matches a pattern a, b or c|
|a*||Matches 0 or more characters a|

|(pattern)||Considers pattern as one character for the above|
|fpatterng||Captures pattern for later reference|
|/b||Anchors to a word boundary|
|/B||Anchors to a non-boundary|
|^pattern||Anchors pattern to the beginning of a line|
|pattern$||Anchors pattern to the end of a line|
|@pattern||Returns the match found only in the beginning of the text|
|%pattern||Returns the first match found, but searches all the text|
|(my|his)||Matches both my pattern and his pattern.|
|/d/d:/d/d(:/d/d)?||Matches time with seconds (01:25:32) or without seconds (02:30).|
|[A-D]/l+||Matches names such as Australia, Bolivia, Canada or Denmark, but not England, Spain or single letters such as A.|
