56 : Some general words about what's going on here ....
57 :
58 : <p>In our file open dialog, usually we display every filter we know. That's how it was before: every filter
59 : lead to an own line in the filter list box, e.g. "StarWriter 5.0 Dokument" or "Microsoft Word 97".</p>
60 :
61 : <p>But then the PM came. And everything changed ....</p>
62 :
63 : <p>A basic idea are groups: Why simply listing all the single filters? Couldn't we draw nice separators
64 : between the filters which logically belong together? I.e. all the filters which open a document in StarWriter:
65 : couldn't we separate them from all the filters which open the document in StarCalc?<br/>
66 : So spoke the PM, and engineering obeyed.</p>
67 :
68 : <p>So we have groups. They're just a visual aspect: All the filters of a group are presented together, separated
69 : by a line from other groups.</p>
70 :
71 : <p>Let's be honest: How the concrete implementation of the file picker service separates the different groups
72 : is a matter of this implementation. We only do this grouping and suggest it to the FilePicker service ...</p>
73 :
74 : <p>Now for the second concept:<br/>
75 : Thinking about it (and that's what the PM did), both "StarWriter 5.0 Dokument" and "Microsoft Word 97"
76 : describe a text document. It's a text. It's of no interest for the user that one of the texts was saved in
77 : MS' format, and one in our own format.<br/>
78 : So in a first step, we want to have a filter entry "Text documents". This would cover both above-mentioned
79 : filters, as well as any other filters for documents which are texts.</p>
80 :
81 : <p>Such an entry as "Text documents" is - within the scope of this file - called "class" or "filter class".</p>
82 :
83 : <p>In the file-open-dialog, such a class looks like an ordinary filter: it's simply a name in the filter
84 : listbox. Selecting means that all the files matching one of the "sub-filters" are displayed (in the example above,
85 : this would be "*.sdw", "*.doc" and so on).</p>
86 :
87 : <p>Now there are two types of filter classes: global ones and local ones. "Text documents" is a global class. As
88 : well as "Spreadsheets". Or "Web pages".<br/>
89 : Let's have a look at a local class: The filters "MS Word 95" and "MS WinWord 6.0" together form the class
90 : "Microsoft Word 6.0 / 95" (don't ask for the reasons. At least not me. Ask the PM). There are a lot of such
91 : local classes ...</p>
92 :
93 : <p>The difference between global and local classes is as follows: Global classes are presented in an own group.
94 : There is one dedicated group at the top of the list, containing all the global groups - no local groups and no
95 : single filters.</p>
96 :
97 : <p>Ehm - it was a lie. Not really at the top. Before this group, there is this single "All files" entry. It forms
98 : it's own group. But this is uninteresting here.</p>
99 :
100 : <p>Local classes must consist of filters which - without the classification - would all belong to the same group.
101 : Then, they're combined to one entry (in the example above: "Microsoft Word 6.0 / 95"), and this entry is inserted
102 : into the file picker filter list, instead of the single filters which form the class.</p>
103 :
104 : <p>This is an interesting difference between local and global classes: Filters which are part of a global class
105 : are listed in there own group, too. Filters in local classes aren't listed a second time - neither directly (as
106 : the filter itself) nor indirectly (as part of another local group).</p>
107 :
108 : <p>The only exception are filters which are part of a global class <em>and</em> a local class. This is allowed.
109 : Beeing cotained in two local classes isn't.</p>
110 :
111 : <p>So that's all what you need to know: Understand the concept of "filter classes" (a filter class combines
112 : different filters and acts as if it's a filter itself) and the concept of groups (a group just describes a
113 : logical correlation of filters and usually is represented to the user by drawing group separators in the filter
114 : list).</p>
115 :
116 : <p>If you got it, go try understanding this file :).</p>
