<b>Hi krita developers,</b></blockquote>
<blockquote style="margin-left:0cm;margin-right:0.05cm;margin-bottom:0cm;line-height:150%;text-align:justify">
This is the idea of tagging implementation in krita. Look at it once
and correct me if I'm wrong .

<b>What is Tagging ?</b></blockquote>
<blockquote style="margin-left:0cm;margin-right:0.05cm;margin-bottom:0cm;line-height:150%;text-align:justify">
Tagging means adding some tags to the resources in krita and call
them according to your use. In Tagging, there are three main
functions</blockquote>
<blockquote style="margin-left:0cm;margin-right:0.05cm;margin-bottom:0cm;line-height:150%;text-align:justify">
1). Adding a Tag – here, we will create a tag and add it to the
resource.</blockquote>
<blockquote style="margin-left:0cm;margin-right:0.05cm;margin-bottom:0cm;line-height:150%;text-align:justify">
2). Deleting a Tag – we can delete a tag for resource.</blockquote>
<blockquote style="margin-left:0cm;margin-right:0.05cm;margin-bottom:0cm;line-height:150%;text-align:justify">
3). Search for resource – By using tags, we can search for
resources which contains particular resource.</blockquote>
<blockquote style="margin-left:0cm;margin-right:0.05cm;margin-bottom:0cm;line-height:150%;text-align:justify">
<b>How we are implementing ?</b></blockquote>
<blockquote style="margin-left:0cm;margin-right:0.05cm;margin-bottom:0cm;line-height:150%;text-align:justify">
<b>1. UI Description</b></blockquote>
<blockquote style="margin-left:0cm;margin-right:0.05cm;margin-bottom:0cm;line-height:150%;text-align:justify">
In the UI, we thought of placing a text field and three radio
buttons for adding, deleting and searching. How UI works for three
functions is described below

<b>2. Code Description</b></blockquote>
<blockquote style="margin-left:0cm;margin-right:0.13cm;line-height:150%;text-align:justify">
For implementing tagging, the first thing we need to do is to store
the tags with resources. For this, we are using QmultiHash object in
koResourceServer.h file.</blockquote>
<blockquote style="margin-left:0cm;margin-right:0.13cm;line-height:150%;text-align:justify">
QMultiHash <Qstring,key > - Qstring is ResourceFilename and key
is tag</blockquote>
<p style="margin-bottom:0cm">QmultiHash would make the lookup for a
tag much faster ..

<p style="margin-bottom:0cm"><i><b>Now Functions :</b></i></p>
<p style="margin-bottom:0cm"><br>

(koResource, string);</p>

</li></ul>
<p style="margin-bottom:0cm"><b>whenever a tag is searched, we call
the function filterTagObjects (string)</b></p>
<p style="margin-bottom:0cm">
</p>
<ul><li><p style="margin-bottom:0cm">we will check the resource and tag

</p>
</li><li><p style="margin-bottom:0cm">Resources names can be retrieved
from m_resources list in koResourceServer</p>
</li><li><p style="margin-bottom:0cm">If resource and tag pair found, we
will display that resource.</p>
</li></ul>
<p style="margin-bottom:0cm"><br>
</p>
<p style="margin-bottom:0cm"><b>whenever a tag is deleted, we will
call the function deleteTagObjects(koResource, string) </b>
</p>
<ul><li><p style="margin-bottom:0cm">we will check for the resource and
tag pair as in filterTagObjects() .</p>
</li><li><p style="margin-bottom:0cm">we will delete that tag using
remove function of QmultiHash object.</p>
<p style="margin-bottom:0cm"></p>
<p style="margin-bottom:0cm">We also add two other functions</p>
<p style="margin-bottom:0cm"></p>
<p style="margin-bottom:0cm" align="JUSTIFY"><i>writeToXML()</i> -
this one will be called at the end of the program, which saves the
data in the QmultiHash object in a XML file in gimp tags.xml format.</p>
<p style="margin-bottom:0cm" align="JUSTIFY"></p>
<p style="margin-bottom:0cm" align="JUSTIFY"><i>ReadFromXML()</i> -
this one will be called at the start up to retrieve the tags and
store them in QmultiHash object.</p>
<p style="margin-bottom:0cm" align="JUSTIFY"></p>
<p style="margin-bottom:0cm" align="JUSTIFY">I think for providing
auto completion, we need to store tags in QstringList.
</p>
<p style="margin-bottom:0cm" align="JUSTIFY"></p>
<p style="margin-bottom:0cm" align="JUSTIFY"> This the idea of the
tagging and its implementation details. Please give me your feed
