    To share an application which is developed for my personal use, but happy to share the B4J source.

    Look4How is a Knowledge Management Application to store & retrieve, from a database, information for a topic which is organized by themes with items, being categories and related memos. The items are sorted alphabetically.
    The application is developed step-by-step. For those interested have a look at the code = a lot to explore.

    The B4J source code is attached for Look4How and the Look4How uploader.

    The B4JHowTo database is not included (too large to attach) and can be requested via email.

    Tell me, your editor, can your editor do code highlighting on it? i.e. code for various langauges e.g vb, html, etc etc.

    No - its one of the areas which is on the todo list. In post #1 mentioned looking into RichTextFX or other. Have not looked further into this yet ...

    Update v0.80 (Build 20180329) [see Post #1]

    Share development progress.
    Look4How has (now) fully replaced my (good old) Delphi application (used for almost 10 years) for capturing and generating howtos and other information.
    The latest version of the B4JHowTos is included in the download and loaded by default.

    NEW: Search Listview context menu: Copy titles - copy the titles found to the clipboard
    NEW: Search Listview context menu: Copy content - copy the titles found with content to the clipboard
    UPD: Search Listview - categories found are listed italic
    NEW: Tools > Find item changed - searchs for items which are changed since certain date in format YYYY-MM-dd (i.e. 2018-01-01)
    UPD: Tools > Search items changed to Find item
    NEW: Tools > Stay on Top - set the application allways on top
    NEW: Editor special functions Date Time, Date, Time
    NEW: Main Form added button for quick access tasks
    UPD: Main Form starts up faster by changing form maximized using primary screen method instead of API setmaximized
    UPD: HTML ColorPicker color search also updates RGB spinner values; Improved color conversion routines
    FIX: Menu item View HTML Source enabled linked to menu item View HTML Preview
    NEW: Tasks context menu tasklist with copy (the selected task to the clipboard) and delete (the selected task)
    NEW: Tasks option to hide completed tasks from the list
    NEW: Tasks add On Hold as a priority (in addition to High, Normal, Low)
    UPD: Tasks export HTML adjusted table size
    Various minor improvements

    Next
    Explore if the JavaFX TextArea, used as the editor, can be replaced by a more advanced editor or ... leave as is because it serves it purpose although not that advanced.

    Excellent work! I like it very much, both the program and the content you are sharing (so much useful information included).

    One nice thing that you could perhaps incorporate within the program would be the possibility of synchronizing data from your website in order to have the content always up-to-date.

    Thank you for sharing!

    Thanks a lot for your appreciation :)

    A starter has been made = the B4J HowTos are generated by Look4How (Menu Theme > Export > HTML Navigation).
    A dedicated unique HTML page is created for each category & memo and then manually uploaded to my website - I need to do that more frequently must admit.
    Will look into uploading via Look4How, as a background task including removing HTML pages which are not required because the category or memo has been deleted.
    Thanks for bringing up.

    Update v0.90 (Build 20180413) [see Post #1]

    Made good progress with Look4How = getting close to v1.0.
    See the change log below. Made quite a bit of changes under the hood.
    Decided NOT to look into alternatives for the JavaFX TextArea control = too much effort, external dependencies might cause issues, complexity.

    Look4HowUploader
    The biggest feature added, is uploading files via FTP using the new application Look4HowUploader (of course developed with B4J).
    Notes:
    • although developed for Look4How, this application can also be used as a generic simple FTP Uploader ... with some enhancements i.e. Select Local Folder, View File Content, Upload Time Information, Encrypted Password saving etc.
    • tested successfully several times uploading 1100 files generated from the B4JHowTos.
    • @b4x: Many thanks for especially the Resumable Subs feature ... and the great B4X Video Tutorials ... and information shared in the forums.
    upload_2018-4-13_14-38-40.png

    NEW: Look4HowUploader to FTP upload files created via Theme > Export > HTML Navigation to a remote server. The uploader is a separate B4J application running standalone
    NEW: Theme > Export > Navigation - Dialog to set options Show Files in Browser and Upload Files; Menu shortcut CTRL+F4
    NEW: Menu Items - Added fontawesome icons to most of the menu items
    NEW: Menu Search - Quick find item, Find item, Find item changed, Go to item... (first, next, prev,last)
    NEW: Tab Search - Button to search from the search history list; max 10 items, the items are not stored when closing the application
    NEW: Items List Search - Buttons to navigate through the list of items (first, prev, next, last) see also Menu Search Go to
    NEW: Help > Author Website - pointer to view what else the author is exploring & making
    NEW: Editor > Special Function > Insert File - Insert the content of a text file at caret position
    NEW: View > Always on Top - set the application always on top
    NEW: Settings JavaPath=java, FTPUploader=Look4HowUploader.jar
    DEL: Menu Tools - Moved Quick find item, Find item, Find item changed to menu Search
    DEL: Tools > Stay on Top - renamed to Always on Top and moved to menu View
    UPD: File > Open Dialog title format set to lightgray
    UPD: Tasks export HTML icon set same as HTML icon mainform
    UPD: MainForm - All buttons style transparent
    UPD: MainForm left split pane - max size increased from 300 to 400
    UPD: Menu Search > Find Item Changed - for month or day < 10, a 0 is pre set to ensure complying the search condition yyyy-MM-dd
    UPD: Help > Help > PDF documentation
    FIX: Tasks search for task entry did not select all tasks meeting the search condition
    Various minor improvements

    Look4How Viewer for the Raspberry Pi

    The goal is to view the content of Look4How databases (SQLite) on a Raspberry Pi by using B4J and the Liberica JDK.
    This application is just out of curiosity if the Liberica JDK can be used with B4J.
    The item (category, memo) content to be displayed as plain text because the WebKit is (currently) not supported by the Liberica JDK v10 (this might change, watch the Liberica developments).
    The B4J UI application runs in full screen, is bit slow but manageable.

    B4J Soure Code attached.
    Note: The sqlite-raspberry.jar is required to run on the Raspberry Pi. Copy the jar to the B4J additional libraries folder. Can be requested via email.

    Read more including Liberica JDK installation instructions.

    What's Next: Look4How Viewer using ABMaterial running on the Raspberry Pi.

    Look4How Viewer WebApp using ABMaterial

    The goal is to view the content of Look4How databases (SQLite) via webbrowser using ABMaterial framework.
    The application has been tested on a PC, Smart Phone and also on Raspberry Pi 3B+ and 2B with good results.

    Source Code attached.
    Note: Not the full ABMaterial files are included, only the B4J project files to share as an example.

    Snapshot UI with Look4How Database B4JHowTo and selected theme B4J Snippets
    upload_2018-6-23_19-17-47.png

    What's Next: Enhancing this solution: Search sidebar ActionButtons Search & Search History, Search History modal sheet with ABMList, copy content on headless Raspberry Pi ...

    Look4How Debian Stretch PC

    Tested Look4How running on a 10 years old Toshiba L350 notebook with Debian Stretch.
    Used Debian Stretch version 4.9.0.6-686-pae as a base.
    After setting up Debian Stretch, installed the openjfx:
    Code:
    sudo apt-get install openjfx
    resulting in openjdk version 1.8.0_171.
    In addition installed and started the B4J Bridge (see screenshot bottom right).

    Notes
    • Look4How runs in a window as designed, which I did not expect (SURPRISE) as thought would behave like a Raspberry Pi, i.e. full screen.
    • The item webview in Look4How is also working.
    • Tested some other B4J UI applications with different sizes and views. All running ok ... so far.
    • Using this notebook with Debian Stretch to mainly experiment with Node-RED and Tinkerforge... but as B4J UI applications can be run as well, will include in the experiments
    • ... would be interesting to know if also working under Ubuntu, Lubuntu or other Linux OS.
