• How can find you an individual image of multiple images on a canvas size

  It's probably something really simple, but I can't for the life of figure me how I can find an individual image of multiple images on a canvas size. for example, I have 3 photos I want to organize 1 large and two others next to him half. How can I change the size of each image on the canvas as when I select the image on a layer sperate, I want to resize it just resizes the entire canvas and not the individual image

  Thank you

  The only method of certain East first resize the images and place them on the backdrop.

  How in a canvas HTML5 can I add multiple images,... is an order of the stack?

  BTW, above you have used:

  window.localStorage.canvasImage;

  It's the same as:

  window.localStorage.getItem ("canvasImage");

  or

  window.localStorage ["canvasImage"];

  ??

  Yes, these 3 are the same, I just used the shorter

• How to set programmatically the current node in a tree view of the ADF.

  Hello
  

  I'm trying to understand how to set programmatically the current node in a tree view of the ADF.

  My use case example is quite simple; If we take the sample application ADF Summit where under Management Summit, we have a tree view on the left with a list of high level of the country which in turn contain a subset of customers; then, in the right pane, we the customer detail information.

  What I'm trying to achieve is a solution by which I can add a new customer, commit and then to the tree show the client newly created as the currently selected entry.

  I use a pop-up dialog box to create my new entry of the customer and everything works well in this area, and my newly created folder is saved in the database.

  I know how to force the tree to cool off, but what I can't understand is how to do so, it highlights the newly created folder.

  Any help would be much appreciated.

• Rendering of the canvas deteriorates proportionately with the size?

  Can someone explain to me how I can avoid the drop in performance of drawing on a canvas, as its size grows?
  What is the reason for this?

  Run even on a canvas runs more slowly, as the canvas size.

  It also seems that, despite "dirty zone" rendered using JavaFX technology, rendering the scene becomes slower as the size of nodes increases (e.g.: the canvas).
  even if most of it is off-screen. Speed is acceptable when the canvas completely fills my screen size, then the entire screen should already be redrawn.
  but as I increase the size, so the node/canvas already extends outside of the window, made performance continuously decreases as the node expands.

  It is corrected, when setCache (true) is applied.
  However, this does NOT improve drawing performance on the Web, where low latency is essential for a painting application.
  Who seems to be involved, as the documentation advises NOT to Cache, if the node changes frequently.
  Surprisingly then, still cached to True on the Web currently drawn on, more CacheHint = SPEED, seems to improve a little speed.

  Anyway, back to the question: why is based on a painting becomes slower with the size, although the same race, covering the same amount of area, is performed?

  My apologies if I seem confused or repeated myself, I am extremely tired. Thank you in advance and good night.

  It's a beautiful Shindoh descriptive answer.  You have a talent for this sort of thing.

  Reproduce your problem

  Your application does not work even on my machine (Java 8u5, Win 7, 64 bit, ATI Radeon HD 4600), except if I drop the size of the canvas to 8Kx8K (probably because I use an older graphics with capabilities of textures limited).  I drop the size of the canvas, I noticed improvements in performance that outline you, 8 k is really slow to update and pretty unusable at 1 K being quite catchy.

  The exception I get a canvas of 10Kx10K is =>

  A few suggestions

  10Kx10K is a very large canvas.

  Creation of such a thing is a really a kind of brute force solution.

  I think that you would need to get smarter about manage you such situations.

  In my view, relying on the library to manage the optimization of these paintings is not the way to go.

  Of course, the library can handle OK, but your tests show otherwise, so you'll have to work on a different solution.

  What you can do, is take some knowledge of the specific area of your application to help optimize the use of the canvas so that you can get with a smaller canvas.

  For example, consider the technique involved in the drafting of an engine of tile in JavaFX. It is average for the rendering of graphics games such as Pokemon or Zelda on a canvas, old-school style.  There is a support data format that is the TileMap, there are control logic that keeps track of the coordinates of the currently visible TileMap and there is a rendering engine that makes just the coordinates of tile currently visible on the screen.  You can apply a similar approach to your application - this would allow you to limit the size of the canvas limited to just the size of the portion of the visible screen.  Of course the nature of TileMaps make them especially well optimized for this approach, so the solution is not directly transferable to your application.

  Another project that demonstrates rendering an area almost infinitely great is the Grezi project that defines a JavaFX zoomable user interface, although it uses the SceneGraph and not canvas for this.

  The question may be "why should I should I put the extra mention, more complex logic in my code to draw effectively on a canvas? ' that is ' Why can't the library take care of these things for me?  I think the answers are:

  1. the current implementation of the Web on various platforms may not completely optimized for the treatment of the dirty area and overflow in the visible region to the areas off the screen.

  2. the implementation of the Web cannot make use of any domain specific design optimizations that your application may be familiar with.

  3. you qualify for an architecture of MVC type for your design in any case.

  4. the needs of canvas to deliver a very versatile solution that makes it work well in many situations, but may be not optimal for your particular situation.

  See for example-online the best optimizer is between your ears.

  You might want to try another option is to use the SceneGraph instead of a canvas.  The optimization of the library around the larger scene graphs and area sale/offscreen surface treatment can be more effective in the case of SceneGraphs compared to paintings, particularly in the case of graphs of scene quite sparsely populated.

  No matter what you do, if you want to render the box for 4 K screens, I think that JavaFX (and even some of his other computer pipeline components such as native libraries, drivers graphic, material interfaces screen etc), are not particularly well optimized for the treatment of these high resolutions at the moment.  This is likely to change over time, but expect problems of teeth if you try to make these resolutions at the moment.

  Another thing that I remember is that, to a lesser degree, JavaFX makes often content to the textures on a video card.  Most video cards have some sort of limit to the maximum size of texture and when this limit is reached, to do a layer of additional conversion somewhere in the library code that maps the content to several textures video card and when this way of rendering is called, things slow down significantly.  This limit may be generally around 8Kx8K 4Kx4K (I'm not sure).

  My guess is that this is probably not the answer you wanted ;-)

• How can I select multiple cells in tableview with javafx only with the mouse?

  I have an application with a tableview in javafx and I want to select more than one cell only with the mouse (something like the selection that exists in excel). I tried with setOnMouseDragged but I cant'n do something because the selection only returns the cell from which the selection started. Can someone help me?

  For events of the mouse to be propagated to other than the node in which nodes the drag started, you must activate a 'full-drag-release press gesture' by calling startFullDrag (...) on the original node. (For more details, see the Javadocs MouseEvent and MouseDragEvent .) You can register for MouseDragEvents on cells of the table in order to receive and process these events.

  Here's a simple example: the user interface is not supposed to be perfect, but it will give you the idea.

• I have been using the functionality of Firefox in which I could have multiple sets of tabs open, but only see the game I was working with. I have updated and now the functionality is Gone

  I have been using the functionality of Firefox in which I could have multiple sets of tabs open, but only see the game I was working with. I have updated and now the feature disappeared. I had a small icon on the top right of my toolbar. I used it all the time to keep windows separated for financial, plans to travel items, news, etc.. Has it been removed from Firefox?

  Hello

  The feature of tab groups is always present. You can try with the button right of the + after the last tab and Customize. If the icon is hidden behind the other, or if it is available inside the mini window customize, you can put it back. If the problem persists, you can also try of reset toolbars and controls: and start to make changes and restart in Safe Mode screen.

• I added the newurl it was google job opening now it shows multiple windows and I have to click on the window of google to optimize

  I added the NewtabUrl 2.2.3 extension while I entered in google when you open a new window and it worked. I updated firefox and now when I open a new tab I get multiple windows and I have to click on the window of google again to see just google so 2 clicks instead of one--I use it very often.

  I don't see any obvious setting in the addon/extension or general settings.

  Hello, firefox has added its own page of the new tab with the release of firefox 13 (for more information, see customize the page new tab), he has probably replaced the newtaburl parameters. You can try reinstalling the NewtabUrl 2.2.3 extension and put your new custom tab page.
  or you can remove the extension and manually set your new tab page: enter Subject: config in the address bar (you will need to confirm the notification), search for the preference named browser.newtab.url, double-click it and change its value to www.google.com or page of your taste.

  You can not.

  You can use a listbox control.

  An alternative solution is to write the code and each selection, the user gives an enum, for example, can be send to a table and invite the user to continue to select...

  What it means that the DNS server instead sends a node adapter directly status request to the IP address involved in the reverse DNS query. When the DNS server gets the NetBIOS name of the node status response, it adds the DNS domain name specified in the WINS - R record the NetBIOS name provided in the node status response and passes the result to the client applicant. ?

• How can I get a file from canvas to display on the server?

  I created a simple slideshow of canvas in CC to animate.  I tested it to animate and in the option film Test browser Animate (Safari) and everything works perfectly.  Then, I followed the instructions in the files OAM CC export animate to Dreamweaver and Adobe Muse | Adobe Dreamweaver tutorials CC to import the OAM in Dreamweaver.  Everything worked fine in Dreamweaver.

  But when I downloaded the files on the remote server, the html file makes its appearance, but the OAM canvas file does not appear.

  The files on the server configuration is duplicated just as they were on the local site.  But still nothing from the OAM is showing on the site of the remote server.  Must something be done on the remote server to make it work correctly?

  Any suggestions that might need to be done to get the CAO of canvas to show on the remote server as it does on the local site?

  Thank you.

  You have a stray closing tag in your markup.  Fix this.

  Rotate text down, I see.  Download your animation assets.

• [HTML5 Canvas] How to change the scene?

  Hello

  I have an animation created in a HTML5 Canvas document. When seen in the browser, it is displayed in the size of the document, which is not surprising, but what I want to do is display the full window size, scaling to fit. Basically, I'm looking for the equivalent AS3 scaleMode and align with the SWF in height and width to 100%. The publication settings is not all the options related to the scaling, so I don't know where to look. How should I do this?

  Thank you!

  Hi all

  Sensitive scaling options are now part of the HTML5 canvas publication settings in the latest version of animate CC (2015.2)
