项目中大致有三个编辑器Editor,我也只是写了最重要的 PatientInfoEditor
一个完整的编辑器的开发过程:
1.继承自EditorPart的PatientInfoEditor 类,主要内容如下:
(1)定义一个用于显示信息的TableViewer
(2)给TableViewer设置ContentProvider,LabelProvider以及Sorter
(3)设置TableViewer的数据Input
(4)设置编辑器的工具栏CoolBar上的按钮:这里将各个Action定义成了内部类,因为它们没有可复用性
Action包括Add,Modify,Delete,Refresh,其中Delete和Refresh很简单,关键是Add和Modify,它们是通过打开一个Dialog来完成的,
具体内容将在下节介绍
为了避免误删除,要有提示:

2.编辑器的输入类EditorInput
这个类只是简单的实现IEditorInput接口,同时实现getName和getTooltipText方法
package com.yinger.patientims.editors.editorInput;
import org.eclipse.jface.resource.ImageDescriptor;
import org.eclipse.ui.IEditorInput;
import org.eclipse.ui.IPersistableElement;
public class PatientInfoEditorInput implements IEditorInput {
@Override
public Object getAdapter(Class adapter) {
return null;
}
@Override
public boolean exists() {
return false;
}
@Override
public ImageDescriptor getImageDescriptor() {
return null;
}
@Override
public String getName() {
return "Patient Information Management";
}
@Override
public IPersistableElement getPersistable() {
return null;
}
@Override
public String getToolTipText() {
return "Hospital Management/Patient Information Management";
}
}
import org.eclipse.jface.resource.ImageDescriptor;
import org.eclipse.ui.IEditorInput;
import org.eclipse.ui.IPersistableElement;
public class PatientInfoEditorInput implements IEditorInput {
@Override
public Object getAdapter(Class adapter) {
return null;
}
@Override
public boolean exists() {
return false;
}
@Override
public ImageDescriptor getImageDescriptor() {
return null;
}
@Override
public String getName() {
return "Patient Information Management";
}
@Override
public IPersistableElement getPersistable() {
return null;
}
@Override
public String getToolTipText() {
return "Hospital Management/Patient Information Management";
}
}
3.TabelViewer的内容和标签提供器
内容提供器
这里getElements方法写的不是很规范,可以参照上节内容
package com.yinger.patientims.views.viewerProvider;
import java.util.List;
import org.eclipse.jface.viewers.IStructuredContentProvider;
import org.eclipse.jface.viewers.Viewer;
/**
* 记住,这里是一个TableViewer的内容提供器,一定要是实现IStructuredContentProvider接口
* 而不是IContentProvider,IStructuredContentProvider接口中定义了getElements方法,这个
* 方法是要实现的!将setInput时传入的list参数转换成Object数组
*/
public class PatientInfoTableViewerContentProvider implements IStructuredContentProvider {
@Override
public Object[] getElements(Object inputElement) {
return ((List)inputElement).toArray();
}
@Override
public void dispose() {
}
@Override
public void inputChanged(Viewer viewer, Object oldInput, Object newInput) {
}
}
import java.util.List;
import org.eclipse.jface.viewers.IStructuredContentProvider;
import org.eclipse.jface.viewers.Viewer;
/**
* 记住,这里是一个TableViewer的内容提供器,一定要是实现IStructuredContentProvider接口
* 而不是IContentProvider,IStructuredContentProvider接口中定义了getElements方法,这个
* 方法是要实现的!将setInput时传入的list参数转换成Object数组
*/
public class PatientInfoTableViewerContentProvider implements IStructuredContentProvider {
@Override
public Object[] getElements(Object inputElement) {
return ((List)inputElement).toArray();
}
@Override
public void dispose() {
}
@Override
public void inputChanged(Viewer viewer, Object oldInput, Object newInput) {
}
}
标签提供器
需要注意的是Table有table的特点,实现getColumnText方法,给相应的列提供对应的文本
package com.yinger.patientims.views.viewerProvider;
import org.eclipse.jface.viewers.ILabelProviderListener;
import org.eclipse.jface.viewers.ITableLabelProvider;
import org.eclipse.swt.graphics.Image;
import com.yinger.patientims.model.Patient;
public class PatientInfoTableViewerLabelProvider implements ITableLabelProvider {
@Override
public void addListener(ILabelProviderListener listener) {
}
@Override
public void dispose() {
}
@Override
public boolean isLabelProperty(Object element, String property) {
return false;
}
@Override
public void removeListener(ILabelProviderListener listener) {
}
@Override
public Image getColumnImage(Object element, int columnIndex) {
return null;
}
@Override//得到列中要显示的文本
public String getColumnText(Object element, int columnIndex) {
Patient patient = (Patient) element;
switch (columnIndex) {//注意:列的索引是从0开始的
case 0:
return patient.getId().toString();
case 1:
return patient.getName();
case 2:
return patient.getSex();
case 3:
return patient.getAge()+"";
case 4:
return patient.getPhone();
case 5:
return patient.getDepartment().getName();
case 6:
return patient.getSickroom().getSickRoomNo()+"";
case 7:
return patient.getSickbed().getSickBedNo()+"";
case 8:
return patient.getAddress();

整个流程的执行过程与上节类似
4.还有一个重要的类:排序器,通过这个类可以实现对TableViewer的排序
tableviewer通过调用doSort方法最终就可以调用到compare方法进行排序
package com.yinger.patientims.editors.viewerSorter;
import org.eclipse.jface.viewers.Viewer;
import org.eclipse.jface.viewers.ViewerSorter;
import com.yinger.patientims.model.Patient;
/**
* 表格查看器的排序器
* 对于给定的列的索引进行排序
*
* 我觉得有一个地方不好,那就是这里的数字!它固定了某一列就是在某列
* 某一列的排序算法也是!还有就是这个compare方法太长了,过于复杂
* ->可以在外部自定义一个类,用于设置列索引和排序方法的统一
* 例如 IDASC=1 IDDSC=-1
*/
public class PatientInfoSorter extends ViewerSorter {
private int column;
public void doSort(int column) {
this.column = column;
}
@Override // 处理排序的方法
public int compare(Viewer viewer, Object e1, Object e2) {
Patient patient1 = (Patient) e1;
Patient patient2 = (Patient) e2;
switch (column) {
case 1:
return patient2.getId().compareTo(patient1.getId());
case -1:
return patient1.getId().compareTo(patient2.getId());
case 2:
return patient2.getName().compareTo(patient1.getName());
case -2:
return patient1.getName().compareTo(patient2.getName());
case 3:
return patient2.getSex().compareTo(patient1.getSex());
case -3:
return patient1.getSex().compareTo(patient2.getSex());
case 4:
return (patient2.getAge() + "").compareTo(patient1.getAge() + "");
case -4:
return (patient1.getAge() + "").compareTo(patient2.getAge() + "");

case -8:
return (patient1.getSickbed().getSickBedNo() + "").compareTo(patient2.getSickbed().getSickBedNo() + "");
case 9:
