From fac454e54925c3411775b5c580aadb4a67ca6a70 Mon Sep 17 00:00:00 2001 From: Sergey Linev Date: Wed, 28 Oct 2026 12:34:21 +0100 Subject: [PATCH 01/10] [jsroot] Provide builtin_jsroot option JSROOT will be installed from github When git clone is used, many files can be deleted which are not necessary - like demos or examples. Let use $JSROOTSYS as custom source for JSROOT Add special dependency that git cloning happens before additional files copied to js/files/ directory --- .../root-ci-config/buildconfig/global.txt | 1 +

When 'autozoom' specified in draw options, histogram zoomed into - non-empty content. Same command available via context menu. -12. Item of 'Text' kind can be created. It is displayed as - plain text in the browser. If property 'mathjax' specified, - MathJax.js library will be loaded and used for rendering. - See httpcontrol.C macro for example. -13. When using foreignObject, provide workaround for absolute positioning - problem in Chrome/Safari, see - - -## Changes in 3.2 -1. Support JSON objects embedding in html pages, produced by THttpServer -2. For small resize of canvas use autoscale functionality of SVG. Only when - relative changes too large, redraw complete canvas again. -3. Use touch-punch.min.js to process touch events with jquery-ui -4. Even when several TH1/TGraph/TF1 objects with fill attribute overlap each other, - one able to get tooltip for underlying objects -5. Use jquery-ui menu for context menu -6. From context menu one could select several options for drawing -7. Provide user interface for executing TTree::Draw on THttpServer -8. 3D graphic (three.js) works only with IE11 - - -## Changes in 3.1 -1. Correctly show tooltips in case of overlapped objects -2. Implement JSROOT.create() method to create supported - in JavaScript ROOT classes like TH1 or TGraph -3. Fix problem with JSROOT.draw in HTML element with zero width (display:none) -4. Provide possibility to load user scripts with JSROOT.BuildSimpleGUI - and JSROOT.AssertPrerequisites, also with main index.htm -5. Support of TCutG drawing -6. Implement hierarchy display (former dtree) with jQuery -7. Fix several problems in drawing optimization -8. Implement dragging objects from hierarchy browser into existing canvas - to superimpose several objects -9. Implement col2 and col3 draw options, using html5 canvas -10. Support 'p' and 'p0' draw options for TH1 class - - -## Development of version 3.0 - -### November 2014 -1. Better font size and position in pave stats -2. Resize/move of element only inside correspondent pad -3. Adjust of frame size when Y-axis exceed pad limits -4. Correct values in tooltip for THStack -5. Exclude drawing of markers from TGraph outside visible range -6. Drawing of canvas without TFrame object -7. Many other small bug fixes and improvements, thanks to Maximilian Dietrich - -### October 2014 -1. Add "shortcut icon" -2. Add demo of online THttpServer - shell script copies data from - running httpserver.C macro on Apache webserver -3. Evaluate 'monitoring' parameter for online server like: - - Parameter defines how often displayed objects should be updated. -4. Implement 'opt' and 'opts' URL parameters for main page. -5. Show progress with scripts loading in the browser window -6. When one appends "+" to the filename, its content read completely with first I/O operation. -7. Implement JS custom streamer for TCanvas, restore aspect ratio when drawing -8. Major redesign of drawing classes. Resize and update of TCanvas are implemented. - All major draw functions working with HTML element id as first argument. -9. Extract 3D drawings into separate JSRoot3DPainter.js script -10. Use newest three.min.js (r68) for 3D drawings, solves problem with Firefox. -11. Introduce generic list of draw functions for all supported classes. -12. Add possibility to 'expand' normal objects in the hierarchy browser. - For instance, this gives access to single elements of canvas, - when whole canvas cannot be drawn. -13. Correct usage of colors map, provided with TCanvas. -14. Introduce JSROOT.redraw() function which is capable to create or update object drawing. -15. In main index.htm page browser can be disabled (nobrowser parameter) and - page can be used to display only specified items from the file -16. Add support of TPolyMarker3D in binary I/O - -### September 2014 -1. First try to handle resize of the browser, - for the moment works only with collapsible layout -2. Also first try to interactively move separation line between - browser and drawing field. -3. Small fix of minor ticks drawing on the axis -4. Introduce display class for MDI drawing. Provide two implementations - - 'collapsible' for old kind and 'tabs' for new kinds. -5. Adjust size of color palette drawing when labels would take more place as provided. -6. Add correct filling of statistic for TProfile, - fix small problem with underflow/overflow bins. -7. Provide way to select display kind ('collapsible', 'tabs') in the simple GUI. -8. Implement 'grid' display, one could specify any number of division like - 'grid 3x3' or 'grid 4x2'. -9. MDI display object created at the moment when first draw is performed. -10. Introduce painter class for TCanvas, support resize and update of canvas drawing -11. Resize almost works for all layouts and all objects kinds. -12.

Method to build simple GUI changed and more simplified :). The example in index.htm. - While loadScript and AssertPrerequisites functions moved to JSROOT, one - can easily build many different kinds of GUIs, reusing provided JSRootCore.js functions. -8. In example.htm also use AssertPrerequisites to load necessary scripts. - This helps to keep code up-to-date even by big changes in JavaScript code. -9. Provide monitoring of online THttpServer with similar interface as for ROOT files. -10. Fix several errors in TKey Streamer, use member names as in ROOT itself. -11. Keep the only version identifier JSROOT.version for JS code -12. One can specify in JSROOT.AssertPrerequisites functionality which is required. - One could specify '2d', 'io' (default) or '3d'. -13. Use new AssertPrerequisites functionality to load only required functionality. -14. When displaying single element, one could specify draw options and monitor property like: - - Such link is best possibility to integrate display into different HTML pages, - using `` -15. Remove 'JSROOTIO.' prefix from _typename. Now real class name is used. -16. Use in all scripts JSROOT as central 'namespace' -17. Introduce context menu in 3D, use it for switch between 2D/3D modes -18. Use own code to generate hierarchical structure in HTML, replace dtree.js which is - extremely slow for complex hierarchies. Dramatically improve performance for - structures with large (~1000) number of items. -19. Deliver to the server title of the objects, display it as hint in the browser. -20. Better handling of special characters in the hierarchies - allows to display - symbols like ' or " in the file structure. - -### July 2014 -1. Migration to d3.v3.js and jQuery v2.1.1 -2. Fix errors in filling of histogram statbox -3. Possibility of move and resize of statbox, title, color palete -4. Remove many (not all) global variables -5. Example with direct usage of JSRootIO graphics -6. Example of inserting ROOT graphics from THttpServer into `` - -### May 2014 -1. This JSRootIO code together with THttpServer class included - in ROOT repository - -### March 2014 -1. Introduce TBuffer class, which plays similar role - as TBuffer in native ROOT I/O. Simplifies I/O logic, - reduce duplication of code in many places, fix errors. - Main advantage - one could try to keep code synchronous with C++. -2. Avoid objects cloning when object referenced several times. -3. Treat special cases (collection, arrays) in one place. - This is major advantage, while any new classes need to be implemented only once. -4. Object representation, produced by JSRootIO is similar to - objects, produced by TBufferJSON class. By this one can exchange - I/O engine and use same JavaSctript graphic for display. -5. More clear functions to display different elements of the file. - In the future functions should be fully separated from I/O part - and organized in similar way as online part. -6. Eliminate usage of gFile pointer in the I/O part. -7. Provide TBufferJSON::JsonWriteMember method. It allows to stream any - selected data member of the class. Supported are: - basic data types, arrays of basic data types, TString, TArray classes. - Also any object as data member can be streamed. -8.
