Pekr 11-Oct-2010 [3741] | any new stuff regarding core of the engine, or styles, which could be tested? |
Henrik 11-Oct-2010 [3742x2] | Validation notes: 1. can't tab out of a field and unfocus does not activate the reactor 2. numeric fields will respond to an empty field or a number. they are string fields for now. |
Pekr, just worked toward getting the validation examples working. Fixed some bugs in this regard. If anything, try to build your own validation example. I'll be working on updated docs, so they correspond to this prototype. | |
Pekr 11-Oct-2010 [3744] | Henrik - generally - do we have per-field validation, or per-form validation? I e.g. don't like systems, which lock me inside a field, untill I correct it. I hope it is the latter :-) |
Andreas 11-Oct-2010 [3745] | Both, afaict from the source. |
Henrik 11-Oct-2010 [3746] | The scope is whatever you want to validate, whether it be a field or a whole form. |
Robert 11-Oct-2010 [3747] | And it won't lock you in the field, it just indicates it's not valid. So you can tab around like mad but the save button might not be enabled. |
Henrik 11-Oct-2010 [3748x2] | BTW, it's subtle, but if you make mistakes and validate, the validation will automatically focus the first field with an error in it. |
So, it will both support Robert's method of a disabled save button and one that only validates at the end. | |
Pekr 11-Oct-2010 [3750] | What I hate most about validations, is sometimes their strictness. I would break anyone's hands, who pushes me to write a phone number to some "standard". The phone number is used by humans anyway, and even then, it can be still parsed even by automat. My number is +420-777-172 171 .... I choose my own format for the readability purposes, and I hate, when the form blocks me :-) |
Henrik 11-Oct-2010 [3751] | well, then you don't have to use it. validators are made from the user's perspective using the MAKE-VALIDATOR function to fit any format supported by the style to validate. |
ChristianE 11-Oct-2010 [3752] | Must have selected value in item list 1, but doesn't mark a non-selection as invalid after marking a selected item as valid and deselecting it by clicking in the list-view somewhere below item "3". |
Gregg 11-Oct-2010 [3753] | This looks like great progress Henrik. |
Henrik 11-Oct-2010 [3754x2] | ChristianE, ok, bug in TEXT-LIST. |
Gregg, thanks. There will be another iteration as new ideas have come up. | |
Pekr 12-Oct-2010 [3756] | Henrik - question to your site being down on ML. I know that it is now available via IP address, but dunno if you want to get it published. Feel free to answer on ML. |
Henrik 12-Oct-2010 [3757] | hrm... I responded and it showed up on the list, saying that my mail address is blocked due to spam. Did it show up? |
Pekr 12-Oct-2010 [3758x2] | it did not show-up yet ... |
Henrik - as for validation example - Numering required panel, 'f8, I have no value there, yet it shows positive validation ... | |
Henrik 12-Oct-2010 [3760x3] | Parser issue. Will see if it can be fixed. |
updated validation.r3. added also a field for the only-chars validator. | |
I'm thinking there is a design issue with validation, particularly the initial state: The latest version will show that the "Only Chars" field validates as OK, which is technically correct, but confusing, as absolutely nothing has been entered in the field. The issue is that the VALIDATE-PANEL/INIT function will see the field prefilled with an empty value and this passes validation. All fields that show a black dot, actually fail validation and a black dot is shown as the initial state. I understand what this means, but it may be confusing for someone who is using the validation system for the first time. The fix is simply to add the NOT-EMPTY validator to the field, for the field to fail validation initially. Is this easy to understand? I've studied the issue with setting an initial state for each field, but then there would be a problem with the validation system understanding prefilled values, and I would have to add functions to the validation system to mimick SET-PANEL that setup fields in a special way. I don't want to bloat the GUI like that. This method works fine, as long as you know what's going on. | |
Pekr 12-Oct-2010 [3763x2] | Are you replying to yourself? |
As for me - this sounds so complicated, that normal person can't know what you are talking about at all. | |
Henrik 12-Oct-2010 [3765x2] | I'm asking the question, but it seems to be difficult to understand the issue. |
Pekr, if you try the validation.r3 file again, you will see one field showing up as OK. | |
Pekr 12-Oct-2010 [3767x4] | I just don't understand, why is that being a design issue? Any design, which pretends empty field belongs to "only chars", is wrong. And if it is difficult to fix, then the validation mechanism design is wrong as well ... |
how is that implemented? Are you using parsers? What is the problem to check for the empty string? | |
The issue is that the VALIDATE-PANEL/INIT function will see the field prefilled with an empty value and this passes validation - why is that so? | |
What is the link to validation docs/proposal? | |
GrahamC 12-Oct-2010 [3771] | Is validation a fundamental gui aspect that has to be dealt with now? |
Pekr 12-Oct-2010 [3772x3] | Not numbers field fails too with an empty field ... |
Graham - that is my ethernal question with the GUI project :-) | |
As for me, I can imagine Henrik doing much more important work, especially, as we have just few basic styles, which are even not working properly yet. But - we can't see the big picture. Henrik's work can go in parallel, and I think that Robert is sane enough to know what he is doing/requesting and why. That means - we have to be missing something ... | |
Henrik 12-Oct-2010 [3775] | Graham, yes. |
Pekr 12-Oct-2010 [3776x2] | I hope soon enough we will be able to see fully working area, navigation by keyboard, tabbing system (including the ability to set the order, skip certain widgets, etc.), styles like tabs, tree (fully keyboard navigation support), table/grid (ditto). With those three styles, we can be kings .... |
I just think that the work is running in multiple levels (native - Cyphre, styles - Rebolek, high-level - Henrik), and at some point in time, it will all settle down and merge together ... | |
Henrik 12-Oct-2010 [3778x2] | Pekr, I see you don't understand the design of the only-chars validator: Each validator is single-purpose. This one checks only if only chars exist in the field. You can combine it with another validator to get stricter validation. |
There is no problem with checking for an empty string, but the only-chars validator does not check for empty strings. The not-empty validator does that. | |
Pekr 12-Oct-2010 [3780x2] | Of course I am tempted to see things we expect most - more complete styleset and at least basically usable gui, but I will test what comes-out, as I think talking about what will come next just makes guys nervous :-) Of course some basic time-frame would be usefull ... |
but only-chars CAN'T be imo true for an empty string, no? :-) | |
Henrik 12-Oct-2010 [3782x2] | Time frame is ASAP. The work is being done for apps (now not one, but two) that need to get into the field by RM Asset as soon as possible. |
Pekr, what if you have a case, where you want both? | |
Pekr 12-Oct-2010 [3784] | Henrik - can you please repost link to your validation related doc? |
Henrik 12-Oct-2010 [3785x2] | The doc is not yet updated for the latest validation prototype. |
Perhaps the discussion should wait until that is completed. | |
Pekr 12-Oct-2010 [3787x2] | Henrik - that would be OK, no? It is imo about perception of what are you expecting. If I ask - non-empty, that means something is entered, whatever. If I ask only-chars, it should validate only if chars are entered = include non-empty state by default ... |
Simply: not-empty - some value of any type has to be entered only-chars - only chars allowed (len > 1) only-numbers - only numerical values allowed (len > 1) | |
Henrik 12-Oct-2010 [3789] | yes. what if you want to allow both empty and only-chars? |
Rebolek 12-Oct-2010 [3790] | some-chars, any-chars? |
