Detailed Description
This class makes it easy to add a search line for filtering the items in a listview based on a simple text search.No changes to the application other than instantiating this class with an appropriate KListView should be needed.

Constructor & Destructor Documentation
|
Constructs a KListViewSearchLine with listView being the KListView to be filtered. If listView is null then the widget will be disabled until a listview is set with setListView(). Definition at line 59 of file klistviewsearchline.cpp. References listView(), queueSearch(), and QLineEdit::textChanged(). |
|
Constructs a KListViewSearchLine without any KListView to filter. The KListView object has to be set later with setListView(). Definition at line 80 of file klistviewsearchline.cpp. References queueSearch(), and QLineEdit::textChanged(). |
|
Destroys the KListViewSearchLine.

Member Function Documentation
|
Returns true if the search is case sensitive. This defaults to false.
Definition at line 98 of file klistviewsearchline.cpp. |
|
Returns the current list of columns that will be searched. If the returned list is empty all visible columns will be searched.
Definition at line 103 of file klistviewsearchline.cpp. |
|
If this is true (the default) then the parents of matched items will also be shown.
Definition at line 108 of file klistviewsearchline.cpp. |
|
Returns the listview that is currently filtered by the search.
Definition at line 113 of file klistviewsearchline.cpp. Referenced by KListViewSearchLine(). |
|
Updates search to only make visible the items that match s. If s is null then the line edit's text will be used. Definition at line 122 of file klistviewsearchline.cpp. References QListViewItem::listView(), and QLineEdit::text(). Referenced by activateSearch(). |
|
Make the search case sensitive or case insensitive.
Definition at line 163 of file klistviewsearchline.cpp. |
|
When a search is active on a list that's organized into a tree view if a parent or ancesestor of an item is does not match the search then it will be hidden and as such so too will any children that match. If this is set to true (the default) then the parents of matching items will be shown.
Definition at line 168 of file klistviewsearchline.cpp. |
|
Sets the list of columns to be searched. The default is to search all, visible columns which can be restored by passing columns as an empty list.
Definition at line 173 of file klistviewsearchline.cpp. |
|
Sets the KListView that is filtered by this search line. If lv is null then the widget will be disabled.
Definition at line 178 of file klistviewsearchline.cpp. References QListViewItem::listView(). |
|
Returns true if item matches the search s. This will be evaluated based on the value of caseSensitive(). This can be overridden in subclasses to implement more complicated matching schemes.

Re-implemented for internal reasons. API not affected. See QLineEdit::mousePressEvent(). Reimplemented from KLineEdit.

|
When keys are pressed a new search string is created and a timer is activated. The most recent search is activated when this timer runs out if another key has not yet been pressed. This method makes

|
When the timer started with queueSearch() expires this slot is called. If there has been another timer started then this slot does nothing. However if there are no other pending searches this starts the list view search.
