  • Tool for making quick UI drafts

    - by Moshe
    I'm looking for a tool that can be used for sketching UI (specifically web UI). The sketches/drafts can look as simple as if it was drawn by hand on a whiteboard. Preferably, this tool should be free/open-source and run on Linux as well as on Windows, but this is not a must. Could you recommend?

  • Positioning the dialog box in the centre of the screen

    - by ame
    I have a dialog box developed in mfc for a Windows CE device and want it to occupy the entire screen. I used the following code to center my dialog box on the lcd screen of the device: CWnd* pWnd = GetDesktopWindow(); CenterWindow(pWnd); However, I still get a tiny sliver of space on the left side of the dialog box, resizing the dialog merely makes it overflow on the right side of the LCD while the tiny space on the left remains (I can see the blue of the win CE desktop behind.) Are there any suggestions to solve this problem? I checked the margin settings for this dialog box in my .rc files and leftmargin and topmargin are both set to 0. I was wondering if I could get the coordinates of the centre of the screen and then place my window one or two points to the left to deal with the current offset. A messy approach I know!

  • [Qt] How to make another window pop up that extends QWidget as opposed to QDialog?

    - by Graphics Noob
    So far I've only had my main window pop up other windows that were QDialogs and I'm not getting it to work with a QWidget. The other window I want to display was designed with the Form Editor, then wrapped in a class called ResultViewer which extends QWidget (as opposed to QDialog). What I want is to have the ResultViewer show its ui in a seperate window. Now when I try to display it the ResultViewer ui just pops up in the main window on top of the mainwindow ui. The code I'm using to display it is this (in my mainwindow.cpp file) ResultViewer * rv = new ResultView(this); rv->show(); The constructor for the ResultViewer looks like this ResultViewer::ResultViewer(QWidget * parent) : QWidget(parent), ui(new Ui::ResultViewer) { ui->setupUi(this); } I've looked through the QWidget documentation a bit but the only thing I can find that may be related is the QWidget::window() function, but the explanation isn't very clear, it just gives an example of changing the title of a window.

  • Is it possible to produce a small preview or thumbnail image of a Crystal report in code?

    - by Lawrence Johnston
    I'm using Crystal to display the reports in my project, and I'd like to be able to display a small preview or thumbnail image of the report to the user when he or she is picking a report to display from my UI. Is there any way to produce these thumbnails dynamically from code? The user has the option to add or remove reports by adding or removing them from the reports folder, so just making all the thumbnail images by hand isn't really an option.

  • Javascript Regex: Testing string for intelligent query

    - by Shyam
    Hi, I have a string that holds user input. This string can contain various types of data, like: a six digit id a zipcode that contains out of 4 digits and two alphanumeric characters a name (characters only) As I am using this string to search through a database, the query type is determined on the type of search, which i want to handle serverside using JavaScript (yes, I am using JavaScript serverside). Searching on StackOverflow, brought me some interesting information, like the .test-method, which seems perfect for my needs. The test-method returns either true or false based on the evaluation on the string using a regex object. I am using this page as a reference: http://www.javascriptkit.com/jsref/regexp.shtml So I am trying to determine the zipcode, by using the following very noobish regex. var r = /[A-Za-z]{2,2}/ As far I can understand, this should limit the amount of occurrences of alphanumeric characters to a maximum of two. See beneath the output of my JavaScript console. > var r = /[A-Za-z]{2,2}/ > var x = "2233AL" > r.test(x) true > var x = "2233A" > r.test(x) false > var x = "2233ALL" > r.test(x) true /* i want this to be false */ > A little help would be really appreciated!

    I need to verify that the provided string has only allowed characters using Oracle regular expressions (REGEXP_LIKE). Allowed chars are: abcdefghijklmnopqrstuvwxyz0123456789_-. Trying to execute SELECT CASE WHEN REGEXP_LIKE('abcdefghijklmnopqrstuvwxyz0123456789_-.' , '^[a-z0-9_\-\.]+$') THEN 'true' ELSE 'false' END tmp FROM dual; results in 'false'. Any ideas on this?

  • RSpec View testing: How to modify params?

    - by sebastiangeiger
    I am trying to test my views with RSpec. The particular view that is causing me troubles changes its appearance depending on a url parameter: link_to "sort>name", model_path(:sort_by => 'name') which results in http://mydomain/model?sort_by=name My view then uses this parameter like that: <% if params[:sort_by] == 'name' %> <div>Sorted by Name</div> <% end %> The RSpec looks like this: it "should tell the user the attribute for sorting order" do #Problem: assign params[:sort_for] = 'name' render "/groups/index.html.erb" response.should have_tag("div", "Sorted by Name") end I would like to test my view (without controller) in RSpec but I can't get this parameter into my params variable. I tried assign in all different flavours: assign[:params] = {:sort_by => 'name'} assign[:params][:sort_by] = 'name' ... no success so far. Every idea is appreciated.

  • Refactoring thick client legacy application

    - by Paul
    I am working on a fat client legacy C++ application which has a lot of business logic mixed in with the presentation side of things. I want to clean things out and refactor the code out completely, so there is a clear seperation of concerns. I am looking at MVC or some other suitable design pattern in order to achieve this. I would like to get recommendations from people who have walked this road before - Do I use MVP or MVC (or another pattern)? What is/are the best practices for undertaking something like this (i.e. useful steps/checks) ?

  • Testing HTTPS files with MAMP

    - by jgreenawalt
    I am running MAMP locally on my laptop, and I like to test as much as I can locally. Unfortunately, since I work on e-commerce stuff (PHP), I normally force ssl in most of the checkout forms and it just fails on my laptop. Is there any easy configuration that I might be missing to allow "https" to run under MAMP? Please note, I know that I could configure Apache by hand, re-compile PHP, etc. but I'm just wondering if there's an easier way for a lazy programmer. Thanks

  • How can two programs talk to each other in Java?

    - by Arnon
    I want to ?reduce? the CPU usage/ROM usage/RAM usage - generally?, all system resources that my app uses - who doesn't? :) For this reason I want to split the preferences window from the rest of the application, and let the preferences window to run as ?independent? program. The preferences program ?should? write to a Property file(not a problem at all) and to send a "update signal" to the main program - which means it should call the update method (that i wrote) that found in the Main class. How can I call the update method in the Main program from the preferences program? To put it another way, is a way to build preferences window that take system resources just when the window appears? Is this approach - of separating programs and let them talk to each other (somehow) - the right approach for speeding up my programs?

  • Visualizing branch topology in git

    - by Benjol
    I'm playing with git in isolation on my own machine, and even like that I find it difficult to maintain a mental model of all my branches and commits. I know I can do a git log to see the commit history from where I am, but is there a way to see the entire branch topography, something like these ascii maps that seem to be used everywhere for explaining branches? .-A---M---N---O---P / / / / / I B C D E \ / / / / `-------------' It just feels like someone coming along and trying to pick up my repository would have difficulty working out exactly what was going on. I guess I'm influenced by AccuRev's stream browser...

  • Login screen delay in CentOS 5.4 x64

    - by user208728
    I was happily running my CentOS 5.4 before something bad happened that somehow corrupted the 'nautilus' package. It stopped me from using the default Gnome Desktop. Then I installed (using yum) the KDE and nautilus later on. Now, KDE is running perfectly with one exception that it takes around 10 minutes before showing up the Login Screen and only a blue screen with mouse pointer keeps showing during those 10 minutes. Thanks in Anticipation. Regards, Talal

  • Center current record in DataGridView

    - by Max
    When programmatically changing the current record in the DataGridView is it possible to make it in such way that this record would be centered (vertically) in the grid? When I change the current record it is shown either as the top row or as the bottom row. I'd like it to be in the middle. Would this be possible/simpler in WPF?

  • How do I link up a button click event between a class and a module automatically?

    - by CowKingDeluxe
    I have this code (which doesn't work): Public Class Form1 End Class Public Module test1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Form1.Button1.Click MsgBox("HI") End Sub End Module I know I could handle the button click event in Form1, and then call a function in test1, but I would like to handle the button click event directly in the test1 module. Is there a way to automatically send UI events from the Form1 class to another module?

  • How to implement the "Edit" menu with "Undo", "Cut", "Paste" and "Copy"?

    - by BastiBense
    Greetings, for one of my applications I'm trying to implement an "Edit" menu. This menu usually has the standard-entries Undo, Cut, Copy and Paste. This menu is not there by default, and users seem to expect it especially on Mac OS X. Is there a an easier way of implementing this, without doing so in every widget manually? Since most widgets have the copy/paste/undo mechanism already implemented via shortcuts, I'd like to provide a few simple menu actions that call them as well. The actions should call whatever widget has the focus first, then they should pass the events upwards the object chain, I guess. I'm using Qt 4.6 on Windows, Linux and Mac OS X. Thanks!

  • How can I get a Dialog style activity window to fill the screen?

    - by Matthias
    I am using an activity with the dialog theme set, and I want it to be full screen. I tried all sorts of things, even going through the WindowManager to expand the window to full width and height manually, but nothing works. Apparently, a dialog window (or an activity with the dialog theme) will only expand according to its contents, but even that doesn't always work. For instance, I show a progress bar circle which has width and height set to FILL_PARENT (so does its layout container), but still, the dialog wraps around the much smaller progress bar instead of filling the screen. There must be a way of displaying something small inside a dialog window but have it expand to full screen size without its content resizing as well?

  • Haskell UI framework?

    - by Lance May
    Is there, by chance, and emerging Haskell UI framework for Windows? I recently took up looking over the language, and from what I see, it would be great little "one-off" applications (elaborate scripts). However, without a good UI framework I can't see it getting in under the smoke and mirrors of the more obvious contenders. I've read that there are many frameworks, but none are full-featured. I'm just wondering if this is something that's on the rise, or is it simply too difficult to get enough developers going in the same direction with one?
