I just added a button that when clicked calls ErrorTipManager.hideAllErrorTips(), and it doesn't seem to matter which field has focus, the error tip is hidden.As for your second point - the See the discussion of -7 above for flex's default behavior and the tradeoffs between 7-bit and 8-bit scanners. -+ specifies that you want flex to generate a C++ scanner class. said... Thursday, August 6, 2009 Always showing error tips (validators) Many people have complained about how Flex 3's error validation messages are not shown unless you hover your mouse over the input his comment is here
This option implies noyywrap (see below). Flex 4 Spark Resizable Controls Please go here for Flex 3 Resizable Containers . A lot of credit goes to Aral Balkin's blog entry on Better form validation in Flex. Note that the macro YY_NUM_RULES gives the total number of rules (including the default rule, even if you use -s), so a correct declaration for ctr is: int ctr[YY_NUM_RULES]; The macro this contact form
The code didn't take into consideration about listeners (for my custom validator validating multiple controls), so it needs to be updated: /** * Called when the validator fires the valid event. In general, when attempting to write a high-speed scanner try to match as much possible in each rule, as it's a big win. Otherwise, a literal 'X' (used to escape operators such as '*') \0 a NUL character (ASCII code 0) \123 the character with octal value 123 \x2a the character with hexadecimal value
For example, you could use: #define YY_DECL float lexscan( a, b ) float a, b; to give the scanning routine the name lexscan, returning a float, and taking two floats as If that works for you then that is great, but I don't think it should care what the value of errorTip.text is. As mentioned above, with %pointer yytext grows dynamically to accommo- date large tokens. Meta-equiv- alence classes are often a big win when using com- pressed tables, but they have a moderate perfor- mance impact (one or two "if" tests and one array look-up per
I have the same question Show 0 Likes(0) 822Views Tags: none (add) datagridContent tagged with datagrid This content has been marked as final. I have been trying to use this in Flex 4 which work well except that is does not handle scrolling when inside a Scroller (as mentioned by digio above). This still does not solve the problem where the error tip remains visible when the parent is hidden or removed (e.g. Note, however, that unless you generate your scan- ner using the -Cf or -CF table compression options, use of -7 will save only a small amount of table space, and make
Finally, here's an example of how to match C-style quoted strings using exclusive start conditions, including expanded escape sequences (but not including checking for a string that's too long): %x str April 28, 2010 at 8:18 AM R.H.A said... It will be the next character scanned. If you need the value of yytext preserved after a call to unput() (as in the above example), you must either first copy it elsewhere, or build your scanner using %array
This is unlike how many other regular expression tools treat negated char- acter classes, but unfortunately the inconsistency is historically entrenched. Furthermore, existing lex programs sometimes access yytext externally using declara- tions of the form: extern char yytext; This definition is erroneous when used with %pointer, but correct for %array. %array defines Any ideas? it works now...Great work, Thanks a lot March 8, 2010 at 12:18 AM Anonymous said...
Great example!Just one question:Is there an easy to to add an icon in front of the error text? this content I am a fairly new to Flex , I was trying to fix it but I couldn't get the tool tip to move with the control. THE GENERATED SCANNER The output of flex is the file lex.yy.c, which contains the scanning routine yylex(), a number of tables used by it for matching tokens, and a number of Please enter a title.
The macro yy_set_bol(at_bol) can be used to control whether the current buffer's scanning context for the next token match is done as though at the beginning of a line. But scanners that always look ahead give dreadful interactive performance; for example, when a user types a newline, it is not recognized as a newline token until they enter another token, Each of the following, if unset (e.g., %option nounput ), results in the corresponding routine not appearing in the generated scanner: input, unput yy_push_state, yy_pop_state, yy_top_state yy_scan_buffer, yy_scan_bytes, yy_scan_string (though yy_push_state() weblink stdinit if set (i.e., %option stdinit) initializes yyin and yyout to stdin and stdout, instead of the default of nil.
Without this option, flex peppers the generated scanner with #line directives so error messages in the actions will be correctly located with respect to either the original flex input file (if Thanks!I noticed that when I use my mouse wheel to scroll up/down my parent application the ErrorTip Box moves to a incorrect position. This way whenever a component is valid the error tip is removed from the ErrorTipManager's cache.
What is this device on the nose of a Bombardier Global 6000? August 26th, 2009 update Fixed a problem where the error tip wasn't being position properly. February 19, 2010 at 10:58 AM Tam said...

A number are equivalent to flex flags or their negation: 7bit -7 option 8bit -8 option align -Ca option backup -b option batch -B option c++ -+ option caseful or case-sensitive I had to make a fix to the ErrorTipManager class to listen for scroll events on the parent containers. Hi Chris,I think I was not clear with my point.For exampleConsider a component, say objCanvas1 which is having some text controls. check over here yy_scan_bytes(const char *bytes, int len) scans len bytes (including possibly NUL's) starting at location bytes.
Note that yyless is a macro and can only be used in the flex input file, not from other source files. - unput(c) puts the character c back onto the input Wouldn't it be nice to have a library of solutions to solve these problems quickly and easily?This book provides just that, with more than 100 solutions to common problems in one and --help are synonyms for -h. -i instructs flex to generate a case-insensitive scan- ner. Changing it in the midst of scanning will have unexpected results since flex buffers its input; use yyrestart() instead.
Have you noticed it? Note also that you cannot use -I in conjunction with -Cf or -CF. To illustrate the uses of start conditions, here is a scanner which provides two different interpretations of a string like "123.456". You cannot use %array when generating C++ scanner classes (the -+ flag). - int yyleng holds the length of the current token. - FILE *yyin is the file which by default
To negotiate these sorts of problems, flex provides a mechanism for creating and switching between multiple input buffers. How does "jus" distinguish between "duty" and "right" What are points, builds, and stats? This is a great tool! Hello,There is one case where any error tips that are being displayed will not track their targets when those targets are repositioned.
YY_INPUT's calling sequence is "YY_INPUT(buf,result,max_size)". If so, how? Hey Chris,Great util. Equivalence classes usually give dramatic reduc- tions in the final table/object file sizes (typi- cally a factor of 2-5) and are pretty cheap perfor- mance-wise (one array look-up per character scanned).
