• How to draw a filled circle in Java?

  - by Roman

  I have a JPanel with a Grid Layout. In the "cells" of the grid I can put different elements (for example JButtons). There is no problems with that. But now I want to put a filled circle in some of the cells. I also would like to relate an ActionListener with these circles. In more details, if I click the circle it disappears from the current cell and appears in another one. How can I do it in Java? I am using Swing.

• Is there a view for inputing integers in Android?

  - by J. Pablo Fernández

  I'm looking for something like the individual parts of the date picker dialog. A view that allows you to input integers (and only integers) that you can limit (between 1 and 10 for example), where you can use the keyboard or the arrows in the view itself. Does it exists? It is for a dialog. A ready-made dialog to request an integer would also help.

• How to disable current page links in ASP.NET MVC?

  - by rem

  I'm investigating ASP.NET MVC now and noticed that in ASP.NET MVC application, which is created by Visual Studio by default, links "Home" and "About" are staying active when the user is on "Home" and "About" page correspondingly, and after clicking on the current page link page is reloading itself. What is the correct approach to disable link which points to the page, a user is already on? How to do it without violating ASP.NET MVC approach?

• How should 4 decimals places behave, being simple yet powerful

  - by vener

  I have a UI question that troubled me on the best method to handle 4 decimal places for prices. In an table already cramped full of data, I would want to simplified the interface to make it not so cluttered. The actual current UI is shown below. http://i41.tinypic.com/bg5tub.jpg The problem is, for a unit price/units/D.Price and Dis.(Discount) to have 4 decimal places ($0.3459) is quite rare but it still happens (5 in 100 entries). This will result a lot of junk decimal places, cluttering up the interface. What is the best solution to this problem? In short, I want to declutter it yet maintain the precision. Note: This is web app

• creating a static vb.net "app" that consist of a single picture

  - by michael

  I need to create a vb.net program that consists of a unmovable, always on top bitmap, with no menu bar or anything, and does not show up in the task bar as program. It needs to always start in the same place. Essentially I need to mask a part of the screen by using a bitmap that blends into the scenery. I am not sure which properties I need to tweak to achieve all of this.

• Put `stdout` in an `NSTextView` while running the a command

  - by Koning Baard XIV

  I'm creating a Cocoa Application, which will need to run the rails command. This command generates an output, and streams it to stdout. I want to show this output to the user in an NSTextView (so basicly stream the stdout to the NSTextView). I don't really care about how I should run the command, as long as I can set the working directory. Can anyone help me? Thanks

• UI: where to display a status result from a drag & drop?

  - by Jason S

  So I've got drag & drop working. When a drop occurs, I do some processing, and sometimes there is a result that I want to make the user aware of. Right now I am just outputting to the console which isn't very nice. What's an appropriate way to display a status result from a drag & drop? Somehow a modal dialog box seems inappropriate, and a status bar is too space-constrained, I think.

• How do I make dynamic windows in Swing?

  - by Roman

  I have a general question. I would like to have a window containing some buttons, radio buttons, text fields and so on. So, user can do something (write text, select options and press buttons). As the result of the user activity window should change it structure/appearance some element should disappear and some appear. How do I program such "updates"? Should I close an old window and open a new one or I can modify content of window without closing it?

• Creating Java Dialogs

  - by mike_hornbeck

  What would be the easiest way for creating a dialog: - in one window I'm giving data for envelope addressing, also set font type from list of sizes - when clicked OK, in the same window or in next window I get preview of how the envelope would look like with the given names, and used selected font size It should look similarly to this : Should I use Jdialog ? Or will JOptionPane will be enough ? The next step will be to choose color of font and background so I must keep that in mind.

• Java swing center JDialog over parent

  - by Chris Drappier

  I have a Java swing application with a button that produces a popup window when a certain action is performed. I'd like to align the center point of the popup window with the center point of the parent window when it is rendered. How can I calculate the x,y coordinates to plug into setLocation() for the popup window? EDIT: just to clarify. I do not want the behavior of setLocationRelativeTo() because that sets the top-left pixel of the popup over the center pixel of the parent frame. I want to set the center pixel of the popup over the center pixel of the parent frame. Also, I'm not interested in whether or not a popup window is good practice. I'm past that now. thanks

• How to use `wx.ProgressDialog` with my own method?

  - by user1401950

  How can I use the wx.ProgressDialog to time my method called imgSearch? The imgSearch method finds image files on the user's pc. How can I make the wx.ProgressDialog run while imgSearch is still running and display how long the imgSearch is taking? Here's my code: def onFind (self,event)# triggered by a button click max = 80 dlg = wx.ProgressDialog("Progress dialog example","An informative message",parent=self, style = wx.PD_CAN_ABORT| wx.PD_APP_MODAL| wx.PD_ELAPSED_TIME| wx.PD_REMAINING_TIME) keepGoing = True count = 0 imageExtentions = ['*.jpg', '*.jpeg', '*.png', '*.tif', '*.tiff'] selectedDir = 'C:\\' imgSearch.findImages(imageExtentions, selectedDir)# my method while keepGoing and count < max: count += 1 wx.MilliSleep(250) if count >= max / 2: (keepGoing, skip) = dlg.Update(count, "Half-time!") else: (keepGoing, skip) = dlg.Update(count) dlg.Destroy()

• Placing elements (panels) within a wx.GridBagSizer

  - by JHarris

  I'm using a gridbagsizer to place two panels within a frame. control_panel = wx.Panel(self, id=ID_CONTROL_PANEL) main_panel = wx.Panel(self, id=ID_MAIN_PANEL) frame_sizer = wx.GridBagSizer(1, 1) frame_sizer.Add(control_panel, (0, 0), (2, 5), flag=wx.EXPAND) frame_sizer.Add(main_panel, (2, 0), (5, 5), flag=wx.EXPAND) frame_sizer.AddGrowableRow(0) frame_sizer.AddGrowableCol(0) self.SetSizer(frame_sizer) I want the control_panel to be above the main_panel (as you can see above). However this is the output I get: I don't know why the top panel is so much larger than the bottom panel, when I've specified the opposite. (2, 5) for the top and (5, 5) for the bottom. It also has a strange behaviour when I resize it smaller, it basically gives me what I want (see image below), but I don't know how to maintain the ratio when I make it larger again. However when you start resizing larger (even by a small amount) you can see (below) the shapes and ratio change dramatically in the other direction (with the bottom becoming much smaller and the top much larger). Still trying to learn this sizers and can't really find this problem with any of the examples I've seen. Also tried experimenting with all the parameters and doing some tests and I can't figure out what's going on here. Any help would be much appreciated.

• .NET (C#): Getting child windows when you only have a process handle or PID?

  - by shea241

  Kind of a special case problem: I start a process with System.Diagnostics.Process.Start(..) The process opens a splash screen -- this splash screen becomes the main window. The splash screen closes and the 'real' UI is shown. The main window (splash screen) is now invalid. I still have the Process object, and I can query its handle, module, etc. But the main window handle is now invalid. I need to get the process's UI (or UI handle) at this point. Assume I cannot change the behavior of the process to make this any easier (or saner). I have looked around online but I'll admit I didn't look for more than an hour. Seemed like it should be somewhat trivial :-( Thanks
