Create a screen capture command script and enter the path

Check the saved file by executing the screen capture button

Settings programs and environments when installing Ubuntu 22.04

 Things to do by default when install Ubuntu 22.04

1. Basic programs

Terminal program - Split window is more convenient than tab view

sudo apt install terminator

Install ssh server for remote connection

sudo apt install openssh-server

sh is symbolized as dash, so change it to bash

sudo ln -sf bash sh

Install for system resource monitoring

sudo snap install htop

Install to use ifconfig

sudo apt install net-tools

2. Install ZSH - Greatly increases efficiency when working on the terminal

After installing zsh, install oh-my-zsh

Install prompt theme - It's easy to use because it looks good

cd .oh-my-zsh/custom/themes

git clone https://github.com/romkatv/powerlevel10k.git

2-1. Installing zsh plugins

With a little typing, it shows the previously executed commands

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

Colorize the input

git clone https://github.com/zdharma-continuum/fast-syntax-highlighting.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/plugins/fast-syntax-highlighting

More convenient when executing the cd command, display the list through fzf and move to the directory to move to

git clone https://github.com/b4b4r07/enhancd.git $ZSH_CUSTOM/plugins/enhancd

cd .oh-my-zsh/custom/plugins

git clone https://github.com/arzzen/calc.plugin.zsh.git

Lognote - Show only specific package logs (1.0 ~)

This function uses information about installed packages, so it proceeds with the app installed first.

 

1. run Package list dialog(click "packages")

2. select Package(select / unselect package : ENTER key or Double click)

3 - 1. apply package - restart Logcat(ex : 2 packages selected)

3 - 2. apply package - restart Logcat (ex : 1 packages / show only selected package)

Lognote - Setting up a shortcut to re-run from the running icon in Ubuntu

 Create an executable icon desktop file.
Path: ~/.local/share/applications/Lognote.desktop
Set the Exec and Icon items according to the installed location.

[Desktop Entry]
Name=Lognote
Comment=Lognote
Exec=/home/USER/lognote/lognote.sh %U
Icon=/home/USER/lognote/lognote.png
Terminal=false
Type=Application
StartupNotify=true
MimeType=text/plain;
Categories=TextEditor;
Keywords=Text;Plaintext;
X-Ubuntu-Gettext-Domain=lognote

If you search for lognote in the Applications menu, you can see that an icon has been created.

If you add it to favorites and run it, the running icon and favorites are separated, and if you ctrl-click the icon after running, there is no response.

If other programs,  new window is created when you ctrl-click it. 

The reason is that "StartupWMClass" is not set.

If you type the "xprop WM_CLASS" command in terminal while the program you need to check is running, the cursor will change.

If you click the the program, WM_CLASS information will be output.

$ xprop WM_CLASS

WM_CLASS(STRING) = "com-blogspot-cdcsutils-lognote-Main", "com-blogspot-cdcsutils-lognote-Main"

Add "StartupWMClass=..." to the desktop file.

[Desktop Entry]
Name=Lognote
Comment=Lognote
Exec=/home/USER/lognote/lognote.sh %U
Icon=/home/USER/lognote/lognote.png
Terminal=false
Type=Application
StartupNotify=true
MimeType=text/plain;
Categories=TextEditor;
Keywords=Text;Plaintext;
X-Ubuntu-Gettext-Domain=lognote
StartupWMClass=com-blogspot-cdcsutils-lognote-Main

You can see that when you ctrl-click, a new window opens without separating it from your favorites.

How to check the size of JLabel before show it on the screen in JDialog

 When configuring a JDialog, there are times when you need to check the size of a JLabel.

Even if you set the text after creating a JLabel, its size is not set.

In this case, if you set the dialog panel and then call pack(), the size of the JLabel will be set and you can read the value.

Then, you can create the necessary UI using the read size value and set the panel again.

When a JLabel is placed next to another component, it is used to fit the window size.

Lognote - My toy project

In a project, the code work is limited

When I say, "I think it will work if I change it like this," I get, "If it doesn't cause any problems, leave it as is."

Since code can cause unexpected issues if changed, I can't change it as I please.

Especially for work...

That's why I thought of the Toy project I read in the book.

Codes that I can modify as I please without affecting my work

When I was thinking about what to make, I thought it would be good if it could help my work, so I started making a log viewer.

Since it started in 2020, I worked on it for quite a long time.

I worked on it when I had time, so it didn't progress quickly, but I think it was made usefully.

When I first made it, there were a lot of errors, so I was embarrassed..

When I looked at the log, I added the parts I thought were necessary and fixed the errors.

Since the development work was done as I wanted and didn't require anyone's permission, it was fun.

Even now, when my head feels like it's stopped, I think about how to change it and apply the changed code.

When you want to freely change the code but can't, and want to relieve that frustration, try thinking about a Toy project, which can be helpful in its own way.
