[Feature Request] Allow 1 instance option

[mu-us61]

Is your feature request related to a problem? Please describe. as it is when i click cherrytree to open it opens a new instance with empty project, I do use only 1 project and want it open even when i click multiple times to cherrytree

Describe the solution you'd like a new option on settings to allow cherrytree to use only 1 instance, so no new empty cherrytree bug I guess

what is your operative system?

Here is how I solved your issue (both initially and later). (My OS: Debian and MX-Linux, with Xfce.)

1) If you only want to open only one Cherrytree document (from the OS default menu for opening applications), then when in your document, at Cherrytree >File >Preferences >Miscellaneous, Miscellaneous, YES Reload Document From Last Session.

2) If you want to efficiently open one (or more) Cherrytree document(s), then create keyboard application shortcut(s) to start Cherrytree with your document opened.

See Cherrytree >Help >Online Manual F1 >5.6. Command Line. "Cherrytree supports command line argument for starting the application via command line. Positional arguments: filepath Defines the document to open in Cherrytree. Replace filepath with the path of a file."

Here are my four keyboard shortcuts, showing command with filepath/filename.ctb, and showing keyboard shortcut.

cherrytree /home/gn/1WORK/CT/gnLinux.ctb       Ctrl+Alt+L
cherrytree /home/gn/1WORK/CT/gnNotes.ctb       Ctrl+Alt+N
cherrytree /home/gn/1WORK/CT/gnQuadr.ctb       Ctrl+Alt+Q
cherrytree /home/gn/1WORK/CT/gnZscratch.ctb    Ctrl+Alt+Z

Each keyboard shortcut efficiently opens a separate filename.ctb. Intentionally or accidentally reentering the keyboard shortcut for an already open filename.ctb will raise (make visible if below other windows) that single Cherrytree instance (and not raise other Cherrytree instances that might also be open). As well, the OS default menu for opening applications remains available for new Cherrytree startup.

yes my settings is already setted for Reload Document From Last Session , but when opening a new instance it does not work if you have already have one open , and why I do that because sometimes it is easy for me to click desktop app instead of using tap or clicking system tray icon

how to make this happen : 1- just open cherrytree with a document from last session 2- open cherrytree again without closing the first one 3- new cherrytree instance opens with empty session , ( first one stays )

what should have happened: it should open same cherrytree instance with loaded default document ( i use only 1 )

my OS is , Debian 11 KDE cherrytree version is 0.99.51

Did you make a keyboard shortcut to your .ctb file?

Does initial use of the shortcut open a Cherrytree session showing your .ctb?

Does subsequent use of the shortcut raise your Cherrytree session when it was hidden below other windows?

I was using flatpak then switch to snap to try if gonna work but result was the same then as a workaround I did as you say and it worked thanks for help, I edit the desktop icon file and added .ctb's path , now it only opens the same instance and only 1 instance

Exec=env BAMF_DESKTOP_FILE_HINT=/var/lib/snapd/desktop/applications/cherrytree_cherrytree.desktop /snap/bin/cherrytree --new_window /home/muhammet/Documents/DriveBackup/CherryTree/21_12_newone.ctb %f
