List selection events are fired when the following methods are used to change the set of selected items (see e774 创建JList组件).
// Create a list and get the model String[] items = {"A", "B", "C", "D"}; JList list = new JList(items); // Select the second item int start = 1; int end = 1; list.setSelectionInterval(start, end); // B // Select the first 3 items start = 0; end = 2; list.setSelectionInterval(start, end); // A, B, C // Select all the items start = 0; end = list.getModel().getSize()-1; if (end >= 0) { list.setSelectionInterval(start, end); // A, B, C, D } // Clear all selections list.clearSelection(); // Select the first item start = 0; end = 0; list.setSelectionInterval(start, end); // A // Add another selection - the third item start = 2; end = 2; list.addSelectionInterval(start, end); // A, C // Deselect the first item start = 0; end = 0; list.removeSelectionInterval(start, end); // C // Select a single item boolean scrollIntoView = true; list.setSelectedValue("B", scrollIntoView); // B
