Function Documentation

void main_window

(

QlContext *

qlc

)

Creates the main QuickList window.

Uses a notebook interface and remains open and visible for as long as the program is running, unlike the old version.

Todo:

move to gconf

gboolean ql_add_fieldinfo	(	QlTabData *	tab,
		QlFieldInfo *	field
	)

Add a new field to the sheet in the specified tab.

{
    gint size;
    g_return_val_if_fail (tab, FALSE);
    g_return_val_if_fail (field, FALSE);

    g_hash_table_insert (tab->file->fields, GINT_TO_POINTER(size) ,field);
    return TRUE;
}

QlContext* ql_context_init

(

void

)

initialise a table of notebook tab data

Definition at line 111 of file dialog_initial.c.

{
    QlContext * qlc;

    qlc = g_new0 (QlContext, 1);
    qlc->tab_table = g_hash_table_new (g_direct_hash, g_direct_equal);
    return qlc;
}

void ql_fieldinfo_foreach	(	QlTabData *	tab,
		QlFieldInfoCB	cb,
		gpointer	user_data
	)

iterate over each field in the tab

Parameters:

	tab	The notebook tab containing the GtkSheet
	cb	QlFieldInfoCB function to pass each field from the sheet.
	user_data	Pointer to data to pass to the callback.

Definition at line 287 of file dialog_initial.c.

{
    g_return_if_fail (tab);
    g_hash_table_foreach (tab->file->fields, cb, user_data);
}

QlContext* ql_get_context

(

GtkWidget *

widget

)

locate the current context

Retrieve the QuickList Context.

Similar to how glade locates the toplevel widget, this routine retrieves the data stored in the toplevel widget and returns the QuickList Context that includes all notebook tabs.

Definition at line 128 of file dialog_initial.c.

{
    QlContext * qlc;
    GtkWidget *toplevel;

    g_return_val_if_fail (widget, NULL);
    toplevel = gtk_widget_get_toplevel (GTK_WIDGET(widget));
    if (!toplevel)
        return NULL;
    if (GTK_WIDGET_TOPLEVEL (toplevel))
    {
        qlc = (QlContext*) g_object_get_data (G_OBJECT(toplevel), QLCONTEXT);
        return qlc;
    }
    return NULL;
}

QlFieldInfo* ql_get_fieldinfo	(	QlTabData *	tab,
		gint	field_index
	)

Get information about a specific field in the tab

Definition at line 238 of file dialog_initial.c.

{
    QlFieldInfo * field;

    g_return_val_if_fail (tab, NULL);
    field = (QlFieldInfo*)g_hash_table_lookup (tab->file->fields,
        GINT_TO_POINTER(field_index));
    return field;
}

QlFileData* ql_get_filedata

(

QlContext *

qlc

)

return the file data for the current notebook tab

Note the use of the context rather than the actual tab - the dim_menu functions need access via the context.

Definition at line 190 of file dialog_initial.c.

{
    gint index;
    QlTabData * tab;

    g_return_val_if_fail (qlc, NULL);
    g_return_val_if_fail (qlc->notebook, NULL);
    index = gtk_notebook_get_current_page (qlc->notebook);
    if (index < 0)
        return NULL;
    tab = (QlTabData*)g_hash_table_lookup (qlc->tab_table,
        GINT_TO_POINTER(index));
    return tab->file;
}

gint ql_get_last_field

(

QlTabData *

tab

)

replace the last_field value

Definition at line 280 of file dialog_initial.c.

{
    g_return_val_if_fail (tab, -1);
    return g_hash_table_size (tab->file->fields);
}

QlTabData* ql_new_tabdata

(

QlContext *

qlc

)

initialise data for a notebook tab

Associates a notebook tab with it's view (sheet or report) and model (the data from the original file).

Definition at line 169 of file dialog_initial.c.

{
    QlTabData * tab;
    gint nindex;

    nindex = 0;
    tab = g_new0 (QlTabData, 1);
    g_return_val_if_fail (ql_viewdata_new (tab), NULL);
    g_return_val_if_fail (ql_filedata_new (tab), NULL);
    tab->qlc = qlc;
    nindex = gtk_notebook_get_n_pages (qlc->notebook);
    g_hash_table_insert (qlc->tab_table, GINT_TO_POINTER(nindex), tab);
    return tab;
}

void ql_remove_fieldinfo	(	QlTabData *	tab,
		gint	field_index
	)

Remove a field from the sheet.

Despite the name, removes the entire field - once the fieldinfo has been removed, the field itself no longer exists.

Definition at line 271 of file dialog_initial.c.

{
    g_return_if_fail (tab);
    g_return_if_fail (g_hash_table_lookup(tab->file->fields,
        GINT_TO_POINTER(field_index)));
    g_hash_table_remove (tab->file->fields, GINT_TO_POINTER (field_index));
}

gboolean ql_set_fieldinfo	(	QlTabData *	tab,
		QlFieldInfo *	field,
		gint	field_index
	)

Set the field information for a specific field in a tab.

Parameters:

	tab	Pointer to the notebook tab containing the GtkSheet
	field	Pointer to the field information to set
	field_index	Index value for the field to change.

Returns:

FALSE on error or if the field_index does not exist, otherwise TRUE.

Definition at line 260 of file dialog_initial.c.

{
    g_return_val_if_fail (tab, FALSE);
    g_return_val_if_fail (field, FALSE);
    g_return_val_if_fail (g_hash_table_lookup(tab->file->fields,
        GINT_TO_POINTER(field_index)), FALSE);
    g_hash_table_replace (tab->file->fields, GINT_TO_POINTER (field_index), field);
    return TRUE;
}
