One of these is used by a TableListBox as the data model for the table's contents.
The virtual methods that you override in this class take care of drawing the table cells, and reacting to events.

Destructor.
|
virtual |
This can be overridden to react to the user double-clicking on a part of the list where there are no rows.
|
virtual |
This callback is made when the user clicks on one of the cells in the table.
The mouse event's coordinates will be relative to the entire table row.
|
virtual |
This callback is made when the user clicks on one of the cells in the table.
The mouse event's coordinates will be relative to the entire table row.
|
virtual |
Override this to be informed when the delete key is pressed.
Reimplemented in juce::PluginListComponent::TableModel.
|
virtual |
Returns a tooltip for a particular cell in the table.
|
virtual |
Returns the best width for one of the columns.
If you implement this method, you should measure the width of all the items in this column, and return the best size.
Returning 0 means that the column shouldn't be changed.
This is used by TableListBox::autoSizeColumn() and TableListBox::autoSizeAllColumns().
|
virtual |
To allow rows from your table to be dragged-and-dropped, implement this method.
If this returns a non-null variant then when the user drags a row, the table will try to find a DragAndDropContainer in its parent hierarchy, and will use it to trigger a drag-and-drop operation, using this string as the source description, and the listbox itself as the source component.
|
pure virtual |
This must return the number of rows currently in the table.
If the number of rows changes, you must call TableListBox::updateContent() to cause it to refresh the list.
Implemented in juce::PluginListComponent::TableModel.
|
virtual |
Override this to be informed when the list is scrolled.
This might be caused by the user moving the scrollbar, or by programmatic changes to the list position.
|
pure virtual |
This must draw one of the cells.
The graphics context's origin will already be set to the top-left of the cell, whose size is specified by (width, height).
Note that the rowNumber value may be greater than the number of rows in your list, so be careful that you don't assume it's less than getNumRows().
Implemented in juce::PluginListComponent::TableModel.
|
pure virtual |
This must draw the background behind one of the rows in the table.
The graphics context has its origin at the row's top-left, and your method should fill the area specified by the width and height parameters.
Note that the rowNumber value may be greater than the number of rows in your list, so be careful that you don't assume it's less than getNumRows().
Implemented in juce::PluginListComponent::TableModel.
|
virtual |
This is used to create or update a custom component to go in a cell.
Any cell may contain a custom component, or can just be drawn with the paintCell() method and handle mouse clicks with cellClicked().
This method will be called whenever a custom component might need to be updated - e.g. when the table is changed, or TableListBox::updateContent() is called.
If you don't need a custom component for the specified cell, then return nullptr. (Bear in mind that even if you're not creating a new component, you may still need to delete existingComponentToUpdate if it's non-null).
If you do want a custom component, and the existingComponentToUpdate is null, then this method must create a new component suitable for the cell, and return it.
If the existingComponentToUpdate is non-null, it will be a pointer to a component previously created by this method. In this case, the method must either update it to make sure it's correctly representing the given cell (which may be different from the one that the component was created for), or it can delete this component and return a new one.

Override this to be informed when the return key is pressed.
|
virtual |
Override this to be informed when rows are selected or deselected.
|

This callback is made when the table's sort order is changed.
This could be because the user has clicked a column header, or because the TableHeaderComponent::setSortColumnId() method was called.
If you implement this, your method should re-sort the table using the given column as the key.
Reimplemented in juce::PluginListComponent::TableModel.
