  • Drawing graphics on top of a JButton

    - by trinth
    I have a situation wherein I have a bunch of JButtons on a GridLayout. I need each of the JButtons to have: a background image (but retain the ability to keep the default button look if needed) custom graphics drawn on top by other classes I have no trouble with the background image, since I am using setIcon() but I am having problems drawing things on top of the background. At one point I was able to draw on top of the button, but after the button was clicked, the drawings disappeared. How can make the button keep this drawing state? Basically, I need a way for my JButtons to have public methods that would allow another class to draw anything on it such as: public void drawSomething() { Graphics g = this.getGraphics(); g.drawOval(3,2,2,2); repaint(); } or public Graphics getGraphics() { return this.getGraphics(); } then another class could do this: button.getGraphics().drawSomething(); The latter is more what I am looking for but the first is equally useful. Is there any way to go about this? Also, overriding the parent class method paintComponent() doesn't help since I need each button to have different graphics.

  • iPhone OS: Rotate just the button images, not the views

    - by Jongsma
    Hi, I am developing an iPad application which is basically a big drawing canvas with a couple of button at the side. (Doesn't sound very original, does it? :P) No matter how the user holds the device, the canvas should remain in place and should not be rotated. The simplest way to achieve this would be to support just one orientation. However, I would like the images on the buttons to rotate (like in the iPhone camera app) when the device is rotated. UIPopoverControllers should also use the users current orientation (and not appear sideways). What is the best way to achieve this? (I figured I could rotate the canvas back into place with an affineTransform, but I don't think it is ideal.) Thanks in advance!

  • Silverlight 4 desktop application sometimes zooms when touching it... and cannot zoom out

    - by TimothyP
    Hi, I have a Silverlight 4 desktop application which I control using a touchscreen (on an HP Touchsmart). Most of the time it works fine but sometimes when clicking something everything just zooms in and every time it happens things get bigger and bigger. The only way to get the normal size again is by restarting the application. Has anybody got any idea what might be causing it ? Does not seem to happen in browser mode. Is there a way to prevent zooming? Thnx

  • Threading vs single thread

    - by user177883
    Is it always guaranteed that a multi-threaded application would run faster than a single threaded application? I have two threads that populates data from a data source but different entities (eg: database, from two different tables), seems like single threaded version of the application is running faster than the version with two threads. Why would the reason be? when i look at the performance monitor, both cpu s are very spikey ? is this due to context switching? what are the best practices to jack the CPU and fully utilize it? I hope this is not ambiguous.

  • Where are the really high quality and complex Swing components?

    - by jouhni
    Looking at Swing, I have the feeling that it comes with many useful and reasonable atomic components in its core. And when I look at the Web there are hundrets of quickly plugged together components (among them many date/time pickers, pimped lists and tables), which have in common that I could easily write them on my own, if I needed them. When I build big software and come to the point where I need a domain-specific component which is really big, I mostly come to the point where I have to write it on my own, which, due to the point that they are not just plugged together lists and tables, isn't done qickly. So, the question is, why are there no Swing component galleries which contain more than just customized date/time pickers or lists with added tree support. Where are the components which really raise the level of abstraction, or are in best case domain-specific?

  • Using thread inter-communication to increase my server app's IO throughput; not sure how

    - by Howard Guo
    My server application creates a new thread for each incoming connection. Incoming requests are serialized in a BlockingQueue. There is one worker thread taking items from the queue, produce a response and send the response through socket. I have noticed a throughput issue: Currently, worker thread is responsible of sending the response message through socket, thus severely wasting processing power and throughput. I am considering: rather than sending the response itself, why not telling network IO threads to send the response? However, when I think about thread inter-communication, I cannot yet figure out how to approach it: Worker thread will produce a response, but how will it inform the response message to IO thread? Is there a standard/best practice? Thank you.

  • In an Android test, how to check that a View is shown?

    - by Jan Zankowski
    Hello, I'm writing a UI test case (using ActivityUnitTestCase) and would like to check if at a given time a View subclass is visible to the user. I've found the View#isShown() method, which claims to do exactly this - checking the visibility field of this element and all its parents - but somehow it always returns "false" for all the elements. I'll be grateful for some help. If it makes it easier, I can paste some code. Also, I found ViewAsserts#assertOnScreen(View origin, View view) but it doesn't seem to do the right thing either - always returns true. Am I perhaps calling it wrong: assertOnScreen(viewImTesting.getRootView(), viewImTesting)? Thanks, Jan

  • Tool to create UI for Linux (Gnome) shell scripts

    - by stwissel
    I'm writing a bunch of Linux shell scripts with complex selections. For now I use zenity for prompts. I'd rather use something where I can show more than one UI element at a time and query it in a script (e.g. a list and some checkboxed and a file picker and an entry field. What are my options?

  • Incorrect sizing of a JPanel in a JScrollPane In Java 1.5

    - by Coder
    Hi, I am making an image loading component which consists of a JPanel containing a JScrollPane, which in turn contains another JPanel. What this component does is allows images to be dropped on top of it, after which point the image is loaded and the inner most JPanel is set to the size of the image dropped. This in turn causes the scroll bars to show up and the user can scroll the image. This all works fine. The problem comes in when i try to auto-shrink the image to the maximum visible area in the outer JPanel. In this case i do a uniform scale of the image to be less than or equal to the width and height of the outer JPanel. What happens now is that both the horizontal and vertical scroll bars show up indicating the the inner JPanel is bigger than the visible area (which should not be the case). I verified that the image is scale to the proper dimensions(ie. the maximum width and height is respected). I also verified that if i decrease the maximum height by 3 pixels, then no scroll bars appear. What i believe the problem is, is that panel.getWidth() and panel.getHeight() don't actually return the visible area (maximum area) that sub components can take up. Ie. there is likely some more width and height taken up by the border around the JPanel or something like that. My question is, how do i get around this problem. Functionally all i want is to determine the maximum size a JPanel can be in a JScrollPane, then set the panel to that size and paint an image over top of it and be assured that the scroll bars of the scroll pane will not show up. Right now the scroll bars are set to AS_NEEDED. Thanks!

  • Problem with displaying graphs on a Qt canvas

    - by Michal Nowotka
    Let's say I'm a Qt newbie. I want a good Qt library for displaying simple graphs. I've found the quanava library. But there is a problem. When I compiled a basic example it looks like graph edges are not painted properly when moving nodes. I don't have any idea where is a bug but this code seems to be rather simple. I think this is a problem with paint method in NodeItem class. Maybe someone has already solved this problem because this library is quite popular.

  • Android Service Multiple Thread Design

    - by Gernot
    Hello, A new question about android and services. Currently I'm developing a App that should send images to a server. It should also be possible to send more images parallel. I made a service that creates for every image a new image. The activity can bind to that service and gather information about the progress. I want to show the current status for every image in a notification (and when the user clicks a notification, an activity with the progress for that image should be shown). But I get several problems with that approach. There are errors with binding, the notification pending event starts the activity completly new, so I lose information about currently sending images and so on. Can someone plase tell me, how I could design such a problem in a appropriate way. thx

  • multi-thread in MS Access, async processing

    - by LanguaFlash
    I know that title sounds crazy but here is my situation. After a certain user event I need to update a couple tables that are "unrelated" to what the user is currently doing. Currently this takes a couple seconds to execute and causes the user a certain amount of frustration. Is there a way to perform my update in a second process or in a manner that doesn't "freeze" the UI of my app while it is processing? Thanks

  • Adding an unknown number of JComponents to a JPanel

    - by Matthew
    Good day, I am building an Applet (JApplet to be exact) and I sub divided that into two panels. The top panel is called DisplayPanel which is a custom class that extends JPanel. The bottom panel is called InputPanel which also extends JPanel. As mentioned above, I can add those two Panel's to the applet and they display fine. The next thing that I would like to do is have the InputPanel be able to hold a random number of JComponent Objects all listed veritcally. This means that the InputPanel should be able to have JButtons, JLabels, JTextFields etc thrown at it. I then want the InputPanel to display some sort of scrolling capability. The catch is that since these two panels are already inside my applet, I need the InputPanel to stay the same size as it was given when added to the Applet. So for example, if my applet (from the web-browser html code) was given the size 700,700, and then the DisplayPanel was 700 by 350, and the InputPanel was below it with the same dimensions, I want to then be able to add lots of JComponents like buttons, to the InputPanel and the panel would stay 700 x 350 in the same position that it is at, only the panel would have scroll bars if needed. I've played with many different combinations of JScrollPane, but just cannot get it. Thank you.

  • Revalidate JPanel's parent frame

    - by Tom Brito
    I need show/hide some fields of my panel, and I want the panel to fit the frame. How could I notify to the parent frame to revalidate? I think in pass the frame to my panel's constructor, but I think may have a way this is already done. I remember that there was a protected attribute in JPanel, but there isn't.. maybe i remembering the wrong component.
