Last modified June 27, 2018. VUE: Visual Understanding Environment modified to suit my (Apollia's) personal tastes. Warning: This might be glitchy. I'm still mostly a Java newbie. <br>The original version of VUE, not modified by Apollia, is available from: []( <br>[]( <br>21:26:44 06/27/2018. After I heard on June 4, 2018 that GitHub was being acquired by Microsoft, I deleted all of my repos from GitHub, and soon relocated most of them to: []( <br>However, I was reluctant to add my modified version of VUE to my own website because the repo was so large - around 344 MiB. So, I decided to shrink the repo by starting a new repo with none of the mysterious .jar files from the original repo included. Starting a new repo seemed safer to me than trying to delete those files from the original repo, since I didn't want pulls from my repo to possibly somehow ruin anyone's copy of the original VUE repo. <br>But, this means to be able to build VUE using this new repo, you'll need to download the deleted files and install them in this repo. I still have yet to write a script to automate that, but I probably will whenever I next feel inspired to work on VUE. The last version of my modified VUE repo containing all those deleted files, and all the original history, is currently available in zip files linked to from this blog post: []( --------- Changelog --------- Jan. 7, 2017: Here's what I managed to do so far: * Turned on debug mode. * Made it so when running VUE on a Unix-like platform, the default Java look-and-feel is now GTK, not Metal. (This is just to make VUE blend in better with my preferred dark GTK theme.) * Switching to the GTK look-and-feel somehow made it impossible to get out of (or into) split-screen mode. So, I got rid of the split-screen that appears at startup. (Told the mViewerSplit object to remove its righthand panel.) * Made it possible to successfully open files and web pages by clicking resource buttons attached to nodes (or as I prefer to call them, bubbles). Now, VUE doesn't try to open GNOME, KDE, Firefox, or Netscape to deal with filepath resources or URL resources attached to bubbles. Instead, VUE tries to send filepaths to a shell command called "for_vue---filepath_opener", and tries to send URLs to a shell command called "for_vue---weburl_opener". Those shell commands can do anything you want. On my system, "for_vue---filepath_opener" is simply a symlink to Puppy Linux's default file-manager, Rox-Filer, and "for_vue---weburl_opener" is a symlink to the Pale Moon web browser. So, now I can do things like launch other programs and scripts, and visit web pages, just by clicking currently inconveniently tiny buttons in VUE. Reminds me a little of HyperCard. * Changed the default background color for new maps to black. * Removed the border from the "Search Everything" box (which apparently doesn't do anything, at least in Puppy Linux) and changed it to green text on a darker green background. ---- Jan. 23, 2017: * A new submenu of the Edit menu called "Etc." I moved the dangerous "Cut" and "Delete" menu items into it. * A new command, "Insert Current Date/Time" (keyboard shortcut: F5). It's in the new "Insert Bubble or Text" submenu of the Edit menu. It inserts dates in this format: 2017-01-23 14:55:49 It works on bubbles or links, but for some reason, doesn't work on text blocks. (Which I didn't fix, because I never use text blocks anyway.) If no bubble or link is selected, or if more than one is selected, a new bubble is created, containing the current date/time. If one bubble or link is selected, the current date/time is added to the label of the selected bubble or link, either at the end of the label, or wherever the caret currently is. * Changed the original dangerous behavior of ESC while editing a bubble label or link label. Originally, ESC would delete all the changes to a bubble label or link label, and even Undo or Redo couldn't retrieve whatever was deleted. Now, ESC leaves the label text alone, and just deselects the bubble or link you were editing. (Which is how text blocks already reacted to ESC, so I didn't change anything related to text blocks.) * Now, bubbles dragged into other bubbles won't be shrunk down and won't have their background colors darkened. And images dragged into bubbles also won't be shrunk down. ---- Feb. 10, 2017: * Formerly, clicking a bubble to edit it would unnecessarily highlight all text. Now, VUE automatically unhighlights that text, so fewer clicks are necessary to edit a bubble. * A new Edit menu item - Deselect. (Keyboard shortcut: ESC) Only works if only one item is selected. * All text in both bubbles and links is now left-justified. * Formerly, the text caret couldn't be seen on dark backgrounds. To fix that, the text caret is given the same color as the current bubble or link's text color. * I attempted to make word wrap work inside bubbles. I got surprisingly far with it, but, unfortunately, word-wrapping went away when I loaded a saved map. And also when changing the text color. So, I reverted those changes, since wordwrap won't be very useful until I figure out how to fix all that. ---- Feb. 12, 2017: * Now you can quickly scroll through your map tabs using your mouse wheel! Uses almost unchanged code from here: * It's now possible to drag and drop tabs to reorder them! Uses code from here: Which is unchanged except for replacing the convertTab method with an unchanged copy of the code from this post: Both of those links go to: * Possibly fixed the longstanding problem of mistaken-seeming "Failed to load map" dialog boxes sometimes popping up when loading a map (which always seemed mistaken because it always looked like the map loaded just fine). All I had to do was comment out two lines in ---- Feb. 16, 2017: * I commented out the code that caused VUE at startup to connect to to look for an updated version of itself. * I commented out and/or modified the worrying-looking code that seemed to be causing VUE to send every web URL the user added to a VUE map to the website * I was dismayed to find that my copy of Java seemed to be, by default, granting all permissions to any Java software I ran. So, I tried to make a Java security policy file for VUE, to try to stop Java from being so darn permissive. I also made some shell scripts to launch VUE using that policy file. That policy file requires the Pro-Grade library - - because astonishingly, without that, Java policies only have a command to "grant" permissions, but not "deny" them! Unfortunately, I still haven't figured out how to block absolutely everything I might possibly want to block, since whether or not I use Pro-Grade, my policy file still fails to block some worrying-looking things. ---- Feb. 18, 2017: * Now Ctrl-T makes a new tab with a new map, instead of inserting a new textblock. (Ctrl-Shift-N no longer creates a new map.) * Added a line (and comments) to the Java security policy. That line seems to make it possible for images to get redrawn. Otherwise, they vanish after a while, even though they appear when you first load a map. ---- Feb. 19, 2017: * Now my VUE launcher scripts can accept arguments, so you can open the maps of your choice at startup. ---- Feb. 21, 2017: * Now it's possible to rename layers while using VUE in Puppy Linux. * Now, URLs you dragdrop into a VUE map are left alone and inserted verbatim. Newlines aren't inserted into them anymore, and they no longer get abbreviated at all. * I made the Layers panel's colors match my dark desktop theme better. * Also changed some other GUI colors. The gradient in the subtitles of the Info panel is now darker. Not sure what my other changes did. * Somehow, changing the Layers panel broke the Categories dropdown in the Info panel. Java is now one of my least favorite programming languages, below Python. ---- Feb. 22, 2017: * Without changing a thing, I discovered that the Categories dropdown actually wasn't totally broken in the copy of VUE I built outside of Eclipse with Ant. When I built VUE with Ant, the Categories dropdown somehow went back to its usual unreliable but somewhat functional enough behavior. I actually have to duplicate my entire VUE folder to build with Ant, because once, when I ran Ant in the same VUE folder Eclipse was using, Eclipse got totally messed up. Would be nice if I knew where Eclipse puts things it builds, but I couldn't figure that out, so I just use Ant to build VUE. * Now Ctrl-3 brings up the Panner (which I use a lot) instead of the Content panel, which I never use. * Using ImageMagick 7.0.5-0, I changed the colors of maybe all images in VUE to make VUE match my personal desktop theme even better. The colors range from semi-bright gold to dark goldenrod. (Might look orangish or brown, depending on your monitor or system display settings.) * The toolbar's highlight is now a brown gradient. * The "focus indicator" (a formerly white box at the lower right of the VUE window) is now black. * I also finally figured out how to change the colors of the title bar of panels (such as Panner, or Layers), including the text color! ---- April 11, 2017: This GitHub issue page about the official VUE repo (which this Apollia/VUE repo was forked from) says the license VUE is under is ECL 2.0: In section 4, "Redistribution", the ECL 2.0 license says (among other things): "You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work otherwise complies with the conditions stated in this License." . So, since I can add my own additional or different license terms, I added the GNU Affero General Public License 3.0 to my modified version of VUE. . Also added a copy of the ECL 2.0 license: ---- Warning: This might be glitchy. I'm still mostly a Java newbie. End of notes by Apollia. ----- Text not by Apollia: ----- Visual Understanding Environment (VUE) is a powerful teaching and presentation tool. 1. Code Organization The code is organized in following folders src - the source files test - automatic junit tests lib - third party libraries used in VUE linux - code specific to linux operating system 2. Compiling and Running The easiest method to compile and run VUE code is using ant version 1.6 or higher. "build.xml" file in src folder contains many tasks to make clean builds of complete VUE application on Linux, Mac and Windows platforms. Here is a list of few useful tasks default - runs VUE (need to run compile task for this to work) clean - deletes all classes compiled earlier compile - compiles the code jar - creates VUE.jar which contains all the required classes and libraries to run VUE 3.
