(1)复制全部
jbutton copyall=new jbutton("复制全部");
copyall.addactionlistener(new actionlistener() {
@override
public void actionperformed(actionevent e) {
string content=area2.gettext();
if(valuewidget.isnullorempty(content)){
return;
}
windowutil.setsysclipboardtext(content);
}
});
public static void setsysclipboardtext(string writeme)
{
clipboard clip = toolkit.getdefaulttoolkit().getsystemclipboard();
transferable ttext = new stringselection(writeme);
clip.setcontents(ttext, null);
}
获取一个"复制"按钮
/***
* get a copy button.
*
* @param tf
* @return
*/
public static jbutton getcopybtn(final jtextcomponent ta) {
jbutton copybtn = new jbutton(menuutil2.action_str_copy);
copybtn.addactionlistener(new actionlistener() {
@override
public void actionperformed(actionevent e) {
if(valuewidget.isnullorempty(ta)){
toastmessage toastmessage = new toastmessage("文本框为null,请确认文本框是否已经创建",3000,color.red);
toastmessage.setvisible(true);
}else{
string input = ta.gettext();
if (!valuewidget.isnullorempty(input)) {
windowutil.setsysclipboardtext(input);
}
});
return copybtn;
(2)黏贴
btnpasteafterdel.addactionlistener(new actionlistener() {
string content = windowutil.getsysclipboardtext();
if (valuewidget.isnullorempty(content)) {
gettextarea().settext(content);
获取一个黏贴按钮:
* get a paste button.
* @param ta
public static jbutton getpastebtn(final jtextcomponent ta) {
jbutton copybtn = new jbutton(menuutil2.action_str_paste);
string input = windowutil.getsysclipboardtext();
if (!valuewidget.isnullorempty(input)) {
ta.settext(input);
(3)给jtextarea 增加快捷键
final jtextarea ta=gettextarea();
keylistener[] keylisteners=ta.getkeylisteners();
ta.addkeylistener(new keyadapter() {
private long lasttimemillsencond;
private long lasttimemillsencondctrl;
private long lasttimemillsencondesc;
public void keypressed(keyevent e) {
if(e.getkeycode() == keyevent.vk_a/*全选*/
||e.getkeycode() == keyevent.vk_c/* 复制 */
||e.getkeycode() == keyevent.vk_f/*格式化*/
||e.getkeycode() == keyevent.vk_z/*剪切*/
||e.getkeycode() == keyevent.vk_v){
// system.out.println(e.getkeycode());
lasttimemillsencondctrl=0;
if(e.isshiftdown()){
if(lasttimemillsencond==0){
lasttimemillsencond=system.currenttimemillis();
}else{
long currenttime=system.currenttimemillis();
long delta=currenttime-lasttimemillsencond;
if(menuutil2.isdoubleclick(delta)){
// system.out.println("双击shift");
lasttimemillsencond=0;
string selectcontent = ta.getselectedtext();
if(valuewidget.isnullorempty(selectcontent)){
return;
}
selectcontent=systemhwutil.deletequotes(selectcontent);
ta.replaceselection(selectcontent);
}else{
lasttimemillsencond=system.currenttimemillis();
}
}
}else if(e.iscontroldown()&&(e.getkeycode() != keyevent.vk_v/*86 */&&e.getkeycode() != keyevent.vk_z/*90*/
&&e.getkeycode() != keyevent.vk_c/*67*/&&e.getkeycode() != keyevent.vk_a/*65*/)){//双击ctrl
// system.out.println("lasttimemillsencondctrl:"+lasttimemillsencondctrl);
if(lasttimemillsencondctrl==0){
lasttimemillsencondctrl=system.currenttimemillis();
long delta=currenttime-lasttimemillsencondctrl;
// system.out.println(lasttimemillsencondctrl+" "+currenttime+" "+delta);
system.out.println("双击ctrl");
lasttimemillsencondctrl=0;
quotesescape(ta,false);
lasttimemillsencondctrl=system.currenttimemillis();
}else if(e.getkeycode() == keyevent.vk_escape){
if(lasttimemillsencondesc==0){
lasttimemillsencondesc=system.currenttimemillis();
if(menuutil2.isdoubleclick(currenttime-lasttimemillsencondesc)){
// system.out.println("双击esc");
lasttimemillsencondesc=0;
string content = ta.gettext();
if(valuewidget.isnullorempty(content)){
boolean iseditable=ta.iseditable();
ta.seteditable(!iseditable);
lasttimemillsencondesc=system.currenttimemillis();
ta.requestfocus();
menuutil2.isdoubleclick 实现如下:
* 通过时间间隔来判断是否是双击(不是鼠标,是键盘)
* @param delta
* @return
*/
public static boolean isdoubleclick(long delta){
return (delta<300&&delta>100);
}
(4)使jtextarea 自动换行
resulttextpane = new assistpopuptextarea();
resulttextpane.setlinewrap(true);
resulttextpane.setwrapstyleword(true);
(5)设置表格数据
private void settabledata2(object[][] datas) {
defaulttablemodel model = new defaulttablemodel(datas, columnnames);
parametertable_1.setmodel(model);
this.parametertable_1.setrowheight(30);
rendtable();
(6)获取表格的数据
* 获取表格中的请求要素
*
protected object[][] getparameter4table(){
tablemodel model= parametertable_1.getmodel();
int rowcount = model.getrowcount();//参数的个数
int columncount=model.getcolumncount();
object[][] data2 = new object[rowcount][];
for (int rowindex = 0; rowindex< rowcount; rowindex++) {
if (!valuewidget.isnullorempty(model.getvalueat(rowindex, 0))) {
object[] objs = new object[columncount];
for (int j = 0; j < columncount; j++) {
object val = model.getvalueat(rowindex, j);
if (!valuewidget.isnullorempty(val)) {
objs[j] = val;
data2[rowindex] = objs;
}
system.out.println(data2.length);
return data2;
(7)获取组件对话框中的数据
string newname = joptionpane.showinputdialog(ta.getparent()/*应该是jframe*/,
"请输入图片高度:", ta.getheight());
if (newname != null)
{
if (newname.equals("")) {
toastmessage toastmessage = new toastmessage("file name can not be empty.",3000,color.red);
return;
specifiedheight=integer.parseint(newname);
}else{/* indicate [cancel] button has been clicked */
toastmessage toastmessage = new toastmessage("已取消",2000,color.red);
toastmessage.setvisible(true);
return;
(8)一个简单的模态窗口(对话框)
