## Description

ExoIconView provides an alternative view on a list model. It displays the model as a grid of icons with labels. Like GtkTreeView, it allows to select one or multiple items (depending on the selection mode, see `exo_icon_view_set_selection_mode()`). In addition to selection with the arrow keys, ExoIconView supports rubberband selection, which is controlled by dragging the pointer.

## Details

### struct ExoIconView

    struct ExoIconView;

Finds the path at the point (`x`, `y`), relative to widget coordinates. In contrast to `exo_icon_view_get_path_at_pos()`, this function also obtains the cell at the specified position. The returned path should be freed with `gtk_tree_path_free()`.

`y` : | The y position to be identified
`path` : | Return location for the path, or `NULL`
`cell` : | Return location for the renderer responsible for the cell at (`x`, `y`), or `NULL`
Returns : | `TRUE` if an item exists at the specified position

Sets the current keyboard focus to be at `path`, and selects it. This is useful when you want to focus the user's attention on a particular item. If `cell` is not `NULL`, then focus is given to the cell specified by it. Additionally, if `start_editing` is `TRUE`, then editing should be started in the specified cell.

This function is often followed by `gtk_widget_grab_focus (icon_view)` in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

`icon_view` : | a ExoIconView
`path` : | a GtkTreePath
`cell` : | a GtkCellRenderer or `NULL`
`start_editing` : | `TRUE` if the specified cell should start being edited.

### exo_icon_view_scroll_to_path ()

    void                exo_icon_view_scroll_to_path        (ExoIconView *icon_view,
                                                             GtkTreePath *path,

Moves the alignments of `icon_view` to the position specified by `path`. `row_align` determines where the row is placed, and `col_align` determines where `column` is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center.

If `use_align` is `FALSE`, then the alignment arguments are ignored, and the tree does the minimum amount of work to scroll the item onto the screen. This means that the item will be scrolled to the edge closest to its current position. If the item is currently visible on the screen, nothing is done.

This function only works if the model is set, and `path` is a valid row on the model. If the model changes before the `tree_view` is realized, the centered path will be modified to reflect this change.

`icon_view` : | A ExoIconView.
`path` : | The path of the item to move to.
`use_align` : | whether to use alignment arguments, or `FALSE`.
`row_align` : | The vertical alignment of the item specified by `path`.
`col_align` : | The horizontal alignment of the item specified by `column`.

This function is a convenience function to allow you to reorder models that support the GtkTreeDragSourceIface and the GtkTreeDragDestIface. Both GtkTreeStore and GtkListStore support these. If `reorderable` is `TRUE`, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model's ::row-inserted and ::row-deleted signals.

This function does not give you any degree of control over the order -- any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.

`icon_view` : | A ExoIconView.
`reorderable` : | `TRUE`, if the list of items can be reordered.

If `enable_search` is set, then the user can type in text to search through the `icon_view` interactively (this is sometimes called "typeahead find").

Note that even if this is `FALSE`, the user can still initiate a search using the "start-interactive-search" key binding.

`icon_view` : | an ExoIconView.
`enable_search` : | `TRUE` if the user can search interactively.

### exo_icon_view_get_search_column ()

    gint                exo_icon_view_get_search_column     (const ExoIconView *icon_view);

Returns the column searched on by the interactive search code.

`icon_view` : | an ExoIconView.
Returns : | the column the interactive search code searches in.

Sets `search_column` as the column where the interactive search code should search in.

If the search column is set, user can use the "start-interactive-search" key binding to bring up search popup. The "enable-search" property controls whether simply typing text will also start an interactive search.

Note that `search_column` refers to a column of the model.

`icon_view` : | an ExoIconView.
`search_column` : | the column of the model to search in, or -1 to disable searching.

Sets the compare function for the interactive search capabilities; note that some like `strcmp()` returning 0 for equality ExoIconViewSearchEqualFunc returns `FALSE` on matches.

Specifying `NULL` for `search_equal_func` will reset `icon_view` to use the default search equal function.

`icon_view` : | an ExoIconView.
`search_equal_func` : | the compare function to use during the search, or `NULL`.
