Dolphin File Manager Search Not Work in Desktop Solution Process

Dolphin File Manager Search Not Work in Desktop Solution Process

In Linux, if SKOTechLearn talk about the distros, KDE make the best for all. There is lots of KDE distro like, KDE Neo, Kubuntu, KaOS, Netrunner, Neptune, Q4OS, Manjaro KDE etc. You can choose according to your desired flavor. But when we talk about file manager, the dolphin makes a great roll as file explorer. So here we solved the problem of Dolphin File manager Search not work in Desktop in KDE.

So, Fist of all, when we search for Linux distro, we find many distro but I personally like KDE base distro. Because, here we find Dolphin file manager with great features, and great searching process comparing all other file manager.

The best part is Dolphin File manager is that it can show the number of files details in status bar during searching process.

But, if you create some folders including sub-folders and files in Desktop and try to search on desktop folder for files, you will get that there is no result show during file search. It shows zero files and folders.

So, we try to find the solution on all over the net, but there is not a suitable solution find. So, SKOTechlearn started for its solution and find the best for KDE users. So, Let’s start for solution with following steps.

 Step 1:
First go to “Settings” option from Start Menu and Click on “System Settings” option from it.

 Step 3:
File Search *-System Settings” screen will appear containing two options “File Search” and “Plasma Search”.

 Step 4:
The main important step is here, go to “File Search” option and click on it. In the right side pane contain “Configure File Search” option.

 Step 5:
You will find “Enable File Search” is tick mark. Unchecked “Enable File Search” option. And press “Apply” button.

Now, after completing all these steps, go to “Dolphin” File Manager and select desktop folder and search anything according to need. And you will find, the searching result will be appear which is not appear before.

The following comparison of Dolphin File search in “Before” and “After” applying above steps.
Comparison before and after Dolphin Setting
Comparison before and after Dolphin Setting
You can see the "0" result before applying steps and after settings, this work well as you can see in above figure.

By the way, there is no need to do these things in Neptune OS, because this KDE distro already has default setting.

So, these are the steps where SKOTechLearn describe how to solve the problem of Dolphin file manager search not work in desktop in KDE Linux.

How to Define or Change Default Main Class in Java NetBeans

How to Define or Change Default Main Class in Java NetBeans

This article related to the jFrame class for Execution time to define as default. By Using Netbeans for Java programming, there is simple process to Define or Change Main Class in Java any time.

Suppose, When I was designing a GUI Swing application in java through NetBeans, Suppose, we add two jFrame class, First jFrame class has designed as entry form and Second has designed as Login class. And I Want to define Login Form class as main class in first priority. But, because we first use Entry Form jFrame, then during run time it default show this as Main Class in Java.

So, for this solution, SKOTechLearn describe that how to Define or Change Main Class in Java NetBeans.

How To Set or Change Any jFrame as Main Class in Java?

Here we will learn very interesting point that we can change main class with two simple ways.

  • Change Main Class in Java at Design Time in NetBeans
  • Change Main Class from Jar file After Build jar

Design or Add jFrame to Create Swing GUI Project in Java NetBeans

 Change Main Class in Java at Design Time in Netbeans :
During design time, you just have to change some settings as described below:
  1. If you create a Project or design application in NetBeans, just go to “Projects” Tab in NetBeans.
  2. After that find your Project and target to right click and find “Properties” option from drop down list and click on it.
  3. You will find that, “Project Properties” window will display including your Project Name.
  4. In this Screen there is “Categories” tree view box containing many option. In this Tree view find “Run” option and select it. 
  5. Now, we will proceed in Changing Main Class in Java Process. So, Find “Main Class:” option. Press “Browse…” Button related to “Main Class:” option. 
  6. Now “Browse Main Classes” Dialog Box will show. In this dialog box, you will find the number of class related to your project will be listed. Just select any one class which you want to define as Main class for your Project.

So, finally, the time to Learn through image description, which are described below.
Main Class Setting in NetBeans

(Simple Tips)How to Open other jFrame through existing jFrame in Java?

So, in this way you can easily change default main class in Java NetBeans.

 Change Main Class from Jar file After Build jar (Executable Jar File) :

Suppose, you have created your jar file or you have to build jar. For Some reason, you want to change the main class. So, what will you do? The answer is given in following way with step by step process.

  • (1):  Go to the jar file’s location, and find your application’s jar file.
  • (2):  Now, right click on jar file and open it as “archive”. I am using 7-Zip to open as archive.
  • (3):  Jar archive contain two folder as “META-INF” and Project name folder. Go to “META-INF” folder and Extract “MANIFEST.MF” file from “META-INF” folder.
  • (4): Open “MANIFEST.MF” file in Notepad. In the last line of Notepad, you will find “Main Class:” containing project name with default class like bellow:
eg.: Main-Class: simple_java. Simple_Java_App 

(Suppose, you have added two class on your application like: “TestJFrame.class” and “Second_Jframe.class”. And you want to make “Second_Jframe.class” as default main class.)

  • (5): So, replace “Simple_Java_App” with “Second_Jframe” like : “ Main-Class: simple_java.Second_Jframe” from Notepad. After that, save Notepad.

Now, If there is complication to understand this process, you can follow the image indication describe bellow.
Change Main Class through Jar MANIFEST
Change Main Class Through Jar File

  • (6): Next step to drag your modified “MANIFEST.MF” file and drop on your jar’s archive’s as “META-INF” folder. Then close archive like bellow.
Modified MANIFEST MF file save in Jar
Drag Modified MANIFEST.MF file on Jar's Archive

  • (7): Finally, Run jar file, you will see that your jar file will be execute with defining or modified main class.

Show Files In Jlist In Java Swing From Specific Path In Netbeans With Complete Details

If you want to make project related with files and want to implement your project with files’ list procedure, you can use jlist. In java, jlist play a very important role for exploring the list of files, database data, dynamic data and static data. Here SKOTechLearn will describe how can we Show Files in jList  in Java Swing from specific path in NetBeans?

First Learn How to Show or Add Data or Items in jList in Java Swing?

So, what will we do for it? There is following steps to Learn it.

Drag jList from “Palette” and find “Swing Contol” and Select “List” control and put it on your Java Swing form and change it’s variable name as “MyFiles_Lst”.

After that you can add jButton with change variable nameBrowseBtn” and Text “Browse..” . And add another jButton with variable nameShowFileBtn” and Text “Show Files”. And add jLabel with variable nameMyPath_lbl”. And Last and one more jLabel with change variable name “MyTotalFiles_Lbl”.
Swing Controls Variable Name Use
jList MyFiles_Lst To show files from specific selected location
jButton BrowseBtn To browse path for and set specific location
jButton ShowFileBtn This will show the files in jList
jLabel MyPath_lbl Get path which was selected from “BrowseBtn”.
jLabel MyTotalFiles_Lbl Get the total number of items from “MyFiles_Lst” control.
Now the following image shows these controls with arrow indication.
Swing Controls with Variable Name in java
After adjusting controls according to desire just as mention above image. Now come to the coding point, what we should do for showing files in jList from specific path in java? The answer is described in below steps.

Example to Show Files in jList in Java

First we import some classes that helps for proceeding above process. The Imported class listed as following:
import java.awt.event.KeyEvent;
import java.nio.file.Files;
import java.nio.file.Paths;
import javax.swing.DefaultListModel;
import javax.swing.JFileChooser;

Also Learn Types of Messages using jOptionPane in Java Swing.

Write code for browsing files’ path from ‘ActionPerformed’ event of “BrowseBtn” .
private void BrowseBtnActionPerformed(java.awt.event.ActionEvent evt) { 
        JFileChooser myfileChooser = new JFileChooser();
        // Use JFileChooser for Open Folder Dialog Box.
        if (Files.isDirectory(Paths.get(MyPath_lbl.getText()))) {
            myfileChooser.setCurrentDirectory(new File(MyPath_lbl.getText()));
        int findresult = myfileChooser.showOpenDialog(this);
        if (findresult == myfileChooser.APPROVE_OPTION) {
            // If We Select any file and click on "Open" button. The specified path will be show in "MyPath_lbl" jLabel

When you click on “BrowseBtn”, a Dailog box “Open” will appear. Now, select then path and select any one of listed file.

Note: In “Open” dialog box, you have to select at least one file for defining the path. Then Click on “Open” Button.

Now SKOTechLearn will write code for listing all files in jList. So, we will choose “ShowFileBtn” jButton and go to its “ActionPerformed” event and will write following code.
private void ShowFileBtnActionPerformed(java.awt.event.ActionEvent evt) {
        String mypath = MyPath_lbl.getText();
        String myfiles = null;
        File myfolder = new File(mypath);
        File[] MylistOfFiles = myfolder.listFiles();
        // 'MylistOfFiles' stores all files' list on array
        DefaultListModel MyJlistModel = new DefaultListModel();
        for (int i = 0; i < MylistOfFiles.length; i++) {
            //Loop 'MylistOfFiles' to get the files in jlist
            if (MylistOfFiles[i].isFile()) {
                myfiles = MylistOfFiles[i].getName();
                    // addElemet will add file's name in jList
  // "MyFiles_Lst.getModel().getSize()" - indicate the total number of files in jList

Now This Action Performed will show the Files in jList.

SkoTechLearn suggest you to please proceed step by step, if you want to get proper result on your project in swing java.
