how can accomplish using timer class in java?

the best approach create class definitions of alphabet , equivalent in morse code. numbers can added well. way can come in text, not sos.

if sos goal, creating class might overkill still practice.

have @ docs timer class

http://docs.oracle.com/javase/7/docs/api/java/util/timer.html << updated link

this method used timer class in illustration below. sos quite possible add together forloop run sequence many seconds, , command led light.

public void schedule(timertask task, long delay, long period)

//usage of timer

import java.util.*;

public class timerdemo {

public static void main(string[] args) { // declare , create task timertask tasknew = new timertask() { // runs our task @override public void run() { system.out.println("timer running..."); } }; // declare , create timer timer mytimer = new timer(); /* schedule timer (task scheduled, delay in ms before task * execution, period in ms between successive tasks executions */ mytimer.schedule(tasknew, 500, 1000); }

}

i hope gives improve example.

c# - Trying to change BorderThickness in DataGrid ColumnHeader -

im using bundle called mahapps metro, i'm trying alter style of datagrid alter default borderthickness of columnheader.

the mahapps metro datagrid command can found here: https://github.com/mahapps/mahapps.metro/blob/master/mahapps.metro/styles/controls.datagrid.xaml

the part i'm trying access custom style is:

<border x:name="backgroundborder" borderthickness="0,0,0,3" grid.columnspan="2" background="{templatebinding background}" borderbrush="{templatebinding borderbrush}" />

currently have:

<style targettype="datagridcolumnheader" x:key="geledigdheader" basedon="{staticresource metrodatagridcolumnheader}"> <setter property="horizontalcontentalignment" value="right"/> <setter property="borderbrush" value="#953735"/> </style>

this changes color want alter thickness, using property="borderthickness" not work, obviously..

well if @ style there given no explicit access borderthickness via binding. since have style can add together line

<border x:name="backgroundborder" borderthickness="0,0,0,3" grid.columnspan="2" background="{templatebinding background}" borderbrush="{templatebinding borderbrush}" borderthickness="{templatebinding borderthickness}"/>
