Maxim 18-Apr-2009 [983x2] | actually, I buy all of my digital enternainment. games, DVDs music, etc. I mean, I (have/do/will) live off of all three mediums... so it would be a bit hypocritical for me not to encourage others in my own trades |
just neighbors complaining, but its ok, I've actually managed to make things worse and solve the direct complaint... hahhaha | |
Graham 18-Apr-2009 [985x2] | I've got a relevant question |
If I maintain copies of data in different gui aspects ... if I update one set at one place, can I automatically update all the other copies? | |
Maxim 18-Apr-2009 [987x3] | go. |
yep. you pipe whatever relevant data is creating the gui. | |
change anyone, they all stay in sync. | |
Graham 18-Apr-2009 [990] | what about rebgui? |
Maxim 18-Apr-2009 [991x2] | they can even have different data in each... as long as its a two-way conversion it would work. |
rebgui, not a clue. | |
Graham 18-Apr-2009 [993] | you're clueless?? |
Maxim 18-Apr-2009 [994] | exactly. I have never had the need to look at or use rebgui, ever. |
Graham 18-Apr-2009 [995] | can you make some deductions |
Maxim 18-Apr-2009 [996x2] | I tried downloading it once and after tortoise svc started fucking up and slowing down my computer, I got fed up, and uninstalled it, and rebgui wen't along with it ... hehe |
I can tell you that its pretty easy to make it work in vid, so it should be pretty easy to make it work in rebgui. | |
Graham 18-Apr-2009 [998] | afterall, it's Rebol, view and data. |
Maxim 18-Apr-2009 [999] | all you need to do is capture the action, send a message to the relevant liquid. if each control has a liquid which is responsible to set the control, when it receives data, they will update by themselves. |
Graham 18-Apr-2009 [1000] | how about a one page example of two text lists upddating each other ? |
Maxim 18-Apr-2009 [1001x3] | in vid? |
well actually, you have to understand, that technically they don't update each other... they really are sharing the same data. | |
by "the same data" I don't mean the same rebol block... but the same data in the sense of individuality... they are two different views of the same original data set. | |
Graham 18-Apr-2009 [1004] | so just don't do a copy/deep! |
Maxim 18-Apr-2009 [1005x8] | whenever one creates a change, that change is performed on the original data set, and everyone is made aware of the new data. |
cause one data might be a string, another an issue, one a word, and still one a tag. | |
but they all share the same string information. | |
you could have a decimal range, and have it expressed in other formats, like colors, or sliders, progress bars... but they still all reflect the same original data. | |
change the page number in the field, the scroll bar updates by itself. and vice versa. | |
one list might be filtered by gender, another by age, but add a new member to the list, and both will reflect the change... however it happened. | |
the advantage, is that there is no "global" understanding of what the data is being used for... each part of an application handles its own use of some data and really isn't aware of the rest of the application, and doesn't care. | |
doesn't have to. | |
Graham 18-Apr-2009 [1013x2] | vid |
yes | |
Maxim 18-Apr-2009 [1015x3] | normally you have to know that whenever the list changes, you have a slew of functions to call, labels to update, what if the cursor changes, due to some insertion, deletion, what if the current selection is deleted... all examples which have to be handled globally... and the more the application grows, the hairier it becomes. |
that will be my next personnal project.. I promise. | |
its easy to do... but right now I am working actually. | |
Graham 18-Apr-2009 [1018] | so it's not that easy then ! |
Maxim 18-Apr-2009 [1019x6] | liquid is not about less code... its about unbreakable and long-term feature creep indiference. |
its not easy, because we have to mix three paradigms into one application. | |
and dataflow is a management layer, so patching a flaky event engine like view's has to be done properly. | |
really hard, I did blood.r which has 16 interconnected fields, in an evening. | |
most of the time was spent with non liquid related things... like vid. | |
hum... I seem to be getting the reichart syndrome... there is a *NOT* missing before "really hard". | |
Graham 18-Apr-2009 [1025] | which is what I was saying, it's not easy. |
Maxim 18-Apr-2009 [1026x4] | easy is a vague term. |
I'd rather say VIEW is the problem. since liquid is pure. | |
and perfect ;-) | |
but no, its not "hard" its just not a 5 line affair. | |
Graham 18-Apr-2009 [1030] | so at what point is there a payoff? |
Maxim 18-Apr-2009 [1031] | most of the time will be spent by me cursing after view trying to get the list to work. |
Graham 18-Apr-2009 [1032] | 16 nodes? |
