问题描述



实现AbstractCPropertyTab的类具有复选框,并且这些的名称和布尔状态应该是保存到.cproject。

解决方案

我解决了自己的问题。也许有人认为这是有用的。



我将介绍两种方法:一种用于保存表上复选框的检查状态,另一种用于初始化复选框。

  / ** 
*保存包的检查状态。
* /
private void saveChecked(){
ICConfigurationDescription desc = getResDesc()。getConfiguration();
ICStorageElement strgElem = null;
try {
strgElem = desc.getStorage(PACKAGES,true);
} catch(CoreException e){
e.printStackTrace();
}

TableItem [] items = pkgCfgViewer.getTable()。getItems();
for(TableItem item:items){
if(item!= null){
String chkd;
if(item.getChecked()){
chkd =true;
} else {
chkd =false;
}
try {
String pkgName = item.getText();
strgElem.setAttribute(pkgName,chkd);
} catch(异常e){
/ *
* INVALID_CHARACTER_ERR:指定无效或
*非法的XML字符。
* /
}
}
}
}

/ **
*初始化包的检查状态存储。
* /
private void initializePackageStates(){
ICConfigurationDescription desc = getResDesc()。getConfiguration();
ICStorageElement strgElem = null;
try {
strgElem = desc.getStorage(PACKAGES,true);
} catch(CoreException e){
e.printStackTrace();
}
TableItem [] items = pkgCfgViewer.getTable()。getItems();
for(TableItem item:items){
String value = strgElem.getAttribute(item.getText());
if(value!= null){
if(value.equals(true)){
item.setChecked(true);
}
}
}
}


How to write programmatically to .cproject file and read back (in Eclipse CDT)?

A class implementing AbstractCPropertyTab has checkboxes and name and boolean state of these should be saved to .cproject.

解决方案

I solved my own question. Maybe someone finds this useful.

I will introduce two methods: one for saving checked state of the checkboxes on the table and one to initialize the checkbox values.

/**
 * Saves checked state of the packages.
 */
private void saveChecked() { 
    ICConfigurationDescription desc = getResDesc().getConfiguration();
    ICStorageElement strgElem = null;
    try {
        strgElem = desc.getStorage(PACKAGES, true);
    } catch (CoreException e) {
        e.printStackTrace();
    }

    TableItem[] items = pkgCfgViewer.getTable().getItems();
    for(TableItem item : items) {
        if(item != null) {
            String chkd;
            if(item.getChecked()) {
                chkd = "true";
            } else {
                chkd = "false";
            }
            try {  
                String pkgName = item.getText();
                strgElem.setAttribute(pkgName, chkd);
            } catch (Exception e) {
                /*
                 * INVALID_CHARACTER_ERR: An invalid or
                 * illegal XML character is specified. 
                 */
            }
        }
    }
}

/**
 * Initializes the check state of the packages from the storage.
 */
private void initializePackageStates() {
    ICConfigurationDescription desc = getResDesc().getConfiguration();
    ICStorageElement strgElem = null;
    try {
        strgElem = desc.getStorage(PACKAGES, true);
    } catch (CoreException e) {
        e.printStackTrace();
    }
    TableItem[] items = pkgCfgViewer.getTable().getItems();
    for(TableItem item : items) {
        String value = strgElem.getAttribute(item.getText());
        if(value!=null) {
            if(value.equals("true")) {
                item.setChecked(true);
            }
        }
    }
}
