[英]SWT how to have table that highlights entire row with single click, and edits cell with double click?
SWT newbie here. SWT 新手在这里。 So, what I want is to be able to highlight a whole row, along with being able to select multiple rows, and make it so that double click edits the cells.
所以,我想要的是能够突出显示整行,以及能够 select 多行,并使其双击编辑单元格。 Is a focusCellManager necessary?
是否需要focusCellManager? Relevant pieces of code:
相关代码:
EditorActivationEvent编辑器激活事件
final ColumnViewerEditorActivationStrategy actSupport =
new ColumnViewerEditorActivationStrategy(this)
{
@Override
protected boolean isEditorActivationEvent
(ColumnViewerEditorActivationEvent event)
{
return event.type ==
ColumnViewerEditorActivationEvent.TRAVERSAL
|| event.eventType ==
ColumnViewerEditorActivationEvent.MOUSE_DOUBLE_CLICK_SELECTION
|| event.eventType ==
ColumnViewerEditorActivationEvent.KEY_PRESSED
|| event.eventType ==
ColumnViewerEditorActivationEvent.PROGRAMMATIC;
}
};
creation of TableViewerEditor创建 TableViewerEditor
TableViewerEditor.create(this,
mgr,
actSupport,
ColumnViewerEditor.TABBING_HORIZONTAL|
ColumnViewerEditor.TABBING_MOVE_TO_ROW_NEIGHBOR|
ColumnViewerEditor.TABBING_VERTICAL|
ColumnViewerEditor.KEYBOARD_ACTIVATION);
code for mgr (focusCellManager):经理(focusCellManager)的代码:
focusCellOwnerDrawHighlighter drawHighlighter = new FocusCellOwnerDrawHighlighter(this);
final TableViewerFocusCellManager mgr = new TableViewerFocusCellManager(this, null);
The tableViewer (doesn't appear in the previous snippers as tableViewer is extended by another class and we use the other class, so I don't want to confuse you): tableViewer(没有出现在之前的截图中,因为 tableViewer 是由另一个 class 扩展的,我们使用另一个 class,所以我不想混淆你):
TableViewer vwr = new TableViewer(tableComposite,SWT.BORDER|SWT.FULL_SELECTION|SWT.MULTI);
Using EditingSupport
on the table columns combined with the following TableViewerEditor seems to work for me:在表格列上使用
EditingSupport
并结合以下 TableViewerEditor 似乎对我有用:
TableViewer viewer = new TableViewer(tableComp, SWT.V_SCROLL | SWT.H_SCROLL | SWT.BORDER | SWT.FULL_SELECTION);
ColumnViewerEditorActivationStrategy actSupport = new ColumnViewerEditorActivationStrategy(viewer) {
@Override
protected boolean isEditorActivationEvent(final ColumnViewerEditorActivationEvent event) {
return event.eventType == ColumnViewerEditorActivationEvent.TRAVERSAL
|| event.eventType == ColumnViewerEditorActivationEvent.MOUSE_DOUBLE_CLICK_SELECTION
|| event.eventType == ColumnViewerEditorActivationEvent.KEY_PRESSED
|| event.eventType == ColumnViewerEditorActivationEvent.PROGRAMMATIC;
}
};
int feature = ColumnViewerEditor.TABBING_MOVE_TO_ROW_NEIGHBOR | ColumnViewerEditor.TABBING_HORIZONTAL
| ColumnViewerEditor.KEYBOARD_ACTIVATION
| ColumnViewerEditor.TABBING_CYCLE_IN_VIEWER;
TableViewerEditor.create(viewer, actSupport, feature);
