  • wxWidgets: Show a window that was marked hidden in the XRC

    - by jdwieber
    I'm new to wxWidgets and DialogBlocks. I have a form that is created using DialogBlocks and saved as an XRC file. Part of the form has a vertical wxStaticBoxSizer into which is placed two wxScrolledWindow elements. I want to only show one at a time based on what data is to be shown to the user, so I have one marked hidden and left the other one visible. In code (C++), when I try to switch the display and show the widget that was hidden in the XRC and hide the one that was not, the one that I hide goes away fine, but the one that I want to show is not visible. If I resize the window however, it appears. Once it has appeard then I can switch back and forth with no issues. I tried many combinations of showing, enabling, invalidating, getting the sizer and calling RecalcSizes, refresh, layout, and some others. I tried them in different combinations too. Simply calling Show will allow me to toggle between the two, but only after I switch to the one that does not show initially and resize the window. From what I see in the docs. the issue is that wxSizer doesn't allocate space for hidden windows, but there is a flag that can be set to override that behavor. My problem is that DialogBlocks does not expose that feature, so if I manually edit the XRC file the modifation will be lost when I, or one of the other devs. saves some changes. Is ther a sequence of calls that I can make to tell the sizer to allocate space? The default OnResize handler does something to cause the sizer to allocate space, but I don't know what that is, or how to do it. This is the flag I found in the docs: wxRESERVE_SPACE_EVEN_IF_HIDDEN Normally wxSizers don't allocate space for hidden windows or other items. This flag overrides this behavior so that sufficient space is allocated for the window even if it isn't visible. This makes it possible to dynamically show and hide controls without resizing parent dialog, for example. This function is new since wxWidgets version 2.8.8 Thanks in advance.

  • I am unsure of how to access a persistence entity from a JSP page?

    - by pharma_joe
    Hi, I am just learning Java EE, I have created a Persistence entity for a User object, which is stored in the database. I am now trying to create a JSP page that will allow a client to enter a new User object into the System. I am unsure of how the JSP page interacts with the User facade, the tutorials are confusing me a little. This is the code for the facade: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Add User to System</title> </head> <body> <h2>Add User</h2> <h3>Please fill out the details to add a user to the system</h3> <form action=""> <label>Email:</label> <input type="text" name="email"><br /> <label>Password:</label> <input type="password" name="name"><br /> <label>Name:</label> <input type="text" name="name"><br /> <label>Address:</label> <input type="text" name="address"><br /> <label>Type:</label> <select name="type"> <option>Administrator</option> <option>Member</option> </select><br /> <input type="submit" value="Add" name="add"/> <input type="reset" value="clear" /> </form> </body> This is the code I have to add a new User object within the User facade class: @Stateless public class CinemaUserFacade { @PersistenceContext(unitName = "MonashCinema-warPU") private EntityManager em; public void create(CinemaUser cinemaUser) { em.persist(cinemaUser); } I am finding it a little difficult to get my head around the whole MVC thing, getting there but would appreciate it if someone could turn the light on for me!

  • What event should I handle to execute code when WinForms application switches from Run mode to Desig

    - by dotnetuser
    I am running a Windows form application and I need to execute a piece of code when I switch to design mode. I have a handler for the OnEnterDesignMode debugger event and this gets hit if I am debugging the application and then switch to design mode. However, this does not get hit if I initially start without debugging and then switch to design mode. What event do I need to handle in order that certain code is executed when switching from Run mode to Design mode?

Some of these types are causing my filestream writer to fail. Is it possible to convert all of the below into a string form. The actual data value is not important, just the ability to differentiate between different values. DWORD ExpandString Binary (is this just the same as byte[] ?) MultiString

  • jquery - "click" on keypress?

    - by WonderBugger
    I have an ajax search form that works fine if you click "submit" in that you enter a zipcode, click the "Enter" button and up pops results instantly. I'm trying to make it so that if the user presses "enter" on the keyboard, it has the same effect. It looks like it's submitting, but no results come up... I tried: if($('#search').length) { $('#zipcode').keyup(function(e) { if(e.keyCode == 13) { e.preventDefault(); $('#search').submit(); } }); }

  • Splitting list into a list of possible tuples

    - by user1742646
    I need to split a list into a list of all possible tuples, but I'm unsure of how to do so. For example pairs ["cat","dog","mouse"] should result in [("cat","dog"), ("cat","mouse"), ("dog","cat"), ("dog","mouse"), ("mouse","cat"), ("mouse","dog")] I was able to form the first two, but am unsure of how to get the rest. Here's what I have so far: pairs :: [a] -> [(a,a)] pairs (x:xs) = [(m,n) | m <- [x], n <- xs]

  • Any way to change the color of a radio button?

    - by Ryan
    I'm working on an android form with a radio group containing a set of radio buttons. From what I can tell there is no way to set the color a radio button highlights when you select it. It seems to always default to some bright green color. Is this something that is editable or no? Thanks

  • Displaying a component in EditorGridPanel without clicking

    - by Tower
    Hi, Is there a way to display a component in EditorGridPanel without the need to click on the cell? The problem I see on this demo is that the checkboxes are not Ext.form.Checkbox components, and not even inherited from it. The checkboxes are simply background images and since I am building a grid that needs ComboBoxes, it will not be simple to apply a similar hack.

  • Are there IDEs in which the code-completion widget is not a linear list?

    - by Uri
    Most mainstream IDEs use code-completion in the form of a linear list of suggestions (typically methods). Are there any IDEs (mainstream or not) or IDE plugins that use a non-linear widget, such as a tree? (e.g., pick category first, then the actual recommendation)? I'm working on an IDE feature and want to make sure I'm not reinventing the wheel or infringing some patent.
