  • Strategies for porting application from Win32 API to GTK+

    - by Vitor Braga
    I have a legacy application written in C, using the raw Win32 API. The general level of abstraction is low and raw dependency on <windows.h> is common. I would like to port this application to GTK+. There are any kind of guidelines or best practices on how to do this? I've previously ported a MFC application to Qt, but the application was very abstracted - it draw it's own set of widgets, for example - and initial porting was very straightforward. I've been thinking at first using Wine to build a native Linux executable and then trying to slowly refactor it into a GTK+ app. Does some one have best practices or previous experiences to share about this?

  • Adding a list of "recent articles" affects SEO

    - by Groo
    We have a site which has a sidebar with sections (or "widgets" if you like) showing stuff like "Recent Articles", "Other Articles by this User", "Similar Articles" etc. The issue is, Google seems to take these links very seriously. In fact, if I have only a single article which is closely related to a certain phrase (and several other pages link to it in their sidebars), when I do a Google search, it lists all those other pages highlighting that one link to the page that should actually be the most relevant one. And these pages don't even mention the phrase anywhere else. It there a common approach with adding these sidebar links? For example, I might add them through ajax after the page is loaded, but then crawlers will have harder time finding them?

  • How can you write tests for Selenium (or similar) which don't fail because of minor or cosmetic changes?

    - by Sam
    I've been spending the last week or so learning selenium and building a series of web tests for a website we're about to launch. it's been great to learn, and I've picked up some xpath and css location techniques. the problem for me though, is seeing little changes break the tests - any change to a div, an id, or some autoid number that helps identify widgets breaks any number of tests - it just seems to be very brittle. so have you written selenium (or other similar) tests, and how do you deal with the brittle nature of the tests (or how do you stop them being brittle), and what sort of tests do you use selenium for?

  • Book suggestions for GUI related topics [closed]

    - by asrijaal
    In the past, I've developed more on the server side, so no big GUI/graphic programming topics have crossed my way so far. I'm switching a little bit to the mobile plattforms (iOS, android) and would like to gather more info on the visual/graphic side. Using the SDK controls/widgets isn't that challenging and I would love to get deeper into the view/presentation layer. Animations, drawing itself, probably OpenGL. Any books that would take me a little deeper in understanding how drawing actually works would be helpful.

  • Request of some opinions about a vertical menu style and some suggestions for the site style [on hold]

    - by AndreaNobili
    I am developing a simple mainly static website using WordPress (because maybe in the future I will add some dynamic content) for a company. The new site have to follow the structure of the old site that requires the presence of a vertical main menu in the left column that contains the link to all the statics pages in the site. This is the old site structure: http://www.saranistri.com/ Now I have installed a new WordPress test site (this is only a test site): http://onofri.org/example/ As you can see in the left columns I have put two main menu vetical widgets that implements a possible choise for the maun menù (the top menù upon the header must be eliminated in the final implementation) I want to know some opinions about: 1) Which of the two version is better? Do you have some additional ideas about the CSS style of this vertical menu? 2) What could I do to give a more professional look to this site? (I know that I have to insert a logo into the header) Tnx Andrea

  • Microformats, Reviews and Duplicate Content

    - by Nicholas
    Let's say I have a site that sells widgets, and the URL structure is like so: /[type-of-widget]/[sub-type]/[widget-name]/ So, a URL for a widget might be: /screwdrivers/philips-screwdrivers/acme-big-screwdriver/ We show reviews on the widget page, and use the appropriate microformat data so Google knows it's a review, etc. Now, what if I want to show random reviews in the "sub-type" and "type-of-widget" landing pages? Will Google ding me for duplicate content, or is it smart enough to know (based on microformat data/etc.) that this is not duplicate content?

  • Chromium et Qt rassemblés dans QtWebEngine, un prototype intègre le navigateur open source dans des interfaces Qt Quick

    Un certain temps après le port de Firefox sur Qt en lieu et place de GTK+, c'est au tour de Chromium, la version open source du navigateur Web de Google, d'être le sujet d'expérimentations. Ce projet ne se compose pas que d'un moteur de rendu, il s'agit d'une implémentation complète d'une plateforme Web, de la pile de protocoles réseau au framework multimédia, le tout disponible sur un grand nombre de plateformes (tout comme Qt). L'objectif récemment poursuivi par des employés de Digia était de laisser des développeurs Qt utiliser des briques de l'environnement Chromium, au sein même de Qt Quick 2 et des widgets. Il s'agi...

  • how to easy change some colors with special theme?

    - by eexp
    i use AuroraMint as my themes. but some colors mess up my opera. when i use "gnome-appearance-properties-customize theme-Colors", i only can found input boxes' text color here. but i still want change background colors in email list (opera use GTK theme here). Gui give only 4 group colors here, so poor. GtkColorScheme=fg_color:#cbf6d4d4bf8c,bg_color:#311133332e14,text_color:#8713a9515723,base_color:#444f47474026,selected_fg_color:#f554ffffe666,selected_bg_color:#9797bfbf6060,tooltip_fg_color:#000000000000,tooltip_bg_color:#f5f5f5f5b5b5 i thought maybe some software can use mouse click to found out widgets under mouse point, for i does not know which widget is email list used (if i change gtkrc file).

  • Framework to implement an in game gui editor

    - by momboco
    I need to do an in game gui editor. The game engine has his own widgets elements and I don't want a gui library that substitute it. The most difficult task is the implementation of the functionality that makes usable to artists and designers. Positioning Resize Alignment between some elements Multiselection Relationship between children and parents Add guides Magnet to place elements quickly Use of layers Undo / Redo ... I'm searching a framework or something like, with these functionalities implemented. And a form of append my own engine to make use of it. It would be ideally a mixing between a tool like Photoshop and libRocket ( engine rendering independent ).

  • gnome-panel has multiple rows -- how to undo that?

    - by towi
    On Ubuntu 12.04 I use openbox with a single "gnome-panel" started. But after trying to configure my two screen in Xinerama mode I got additional rows of panels each time X restarted. And despite I completely reverted to my one-screen-X-config the gnome-panel displayed has 4 rows (4 at top sreen, 4 at bottom) only the outermost row has content, the other 3 are empty there is only one gnome-panel process running some widgets appear 4 times, too, although they run only once when I switch away from openbox using unity I am back to 1 row temporarily What went wrong here? How do I undo that? Things that did not help: rm -Rf .gnome2 .gconf/ .compiz-1/ pkill panel, and restarting it

  • Recommendations for taskbar

    - by user210551
    I recently updated to Ubuntu 13.10 and now tint2 stopped working. Better yet: it works, I just can not see it as the all bar is now transparent. Since Tint2 is no longer maintained I doubt it will be updated hence I'm now looking into alternative is there are any. In short: looking for a simple taskbar that sits at the bottom of the screen and that lists applications per window (no groupping!). Don't need fancy animations or widgets/features. Any ideas?

  • [GWT2] UiBinder work with ToggleButton

    - by EnToutCas
    I'm liking the new GWT2 UiBinder, however, it's not clear whether certain things are achievable using the declarative UI style. For instance, ToggleButton only takes the image instances at construction time (no setters for up/down images). As I understand, UiBinder works in a JavaBean-like reflective way, where the assignable attributes are mapped to corresponding setters. Is this style possible with widgets like ToggleButton, where certain attributes have to be specified at construction time? <g:ToggleButton ui:field="myBtn"></g:ToggleButton>

  • multiple stateful iframes per page will overwrite JSESSIONID?

    - by Nikita
    Hello, Looking for someone to either confirm or refute my theory that deploying two iframes pointing to two different stateful pages on the same domain can lead to JSESSIONIDs being overwritten. Here's what I mean: Setup suppose you have two pages that require HttpSession state (session affinity) to function correctly - deployed at http://www.foo.com/page1 and http://www.foo.com/page2 assume www.foo.com is a single host running a Tomcat (6.0.20, fwiw) that uses JSESSIONID for session id's. suppose these pages are turned into two iframe widgets to be embedded on 3rd party sites: http://www.site.com/page1" / (and /page2 respectively) suppose there a 3rd party site that wishes to place both widgets on the same page at http://www.bar.com/foowidgets.html Can the following race condition occur? a new visitor goes to http://www.bar.com/foowidgets.html browser starts loading URLs in foowidgets.html including the two iframe 'src' URLs because browsers open multiple concurrent connections against the same host (afaik up to 6 in chrome/ff case) the browser happens to simultaneously issue requests for http://www.foo.com/page1 and http://www.foo.com/page2 The tomcat @ foo.com receives both requests at about the same time, calls getSession() for the first time (on two different threads) and lazily creates two HttpSessions and, thus, two JSESSIONIDs, with values $Page1 and $Page2. The requests also stuff data into respective sessions (that data will be required to process subsequent requests) assume that the browser first receives response to the page1 request. Browser sets cookie JSESSIONID=$Page1 for HOST www.foo.com next response to the page2 request is received and the browser overwrites cookie JSESSIONID for HOST www.foo.com with $Page2 user clicks on something in 'page1' iframe on foowidgets.html; browser issues 2nd request to http://www.foo.com/page1?action=doSomethingStateful. That request carries JSESSIONID=$Page2 (and not $Page1 - because cookie value was overwritten) when foo.com receives this request it looks up the wrong HttpSession instance (because JSESSIONID key is $Page2 and NOT $Page1). Foobar! Can the above happen? I think so, but would appreciate a confirmation. If the above is clearly possible, what are some solutions given that we'd like to support multiple iframes per page? We don't have a firm need for the iframes to share the same HttpSession, though that would be nice. In the event that the solution will still stipulate a separate HttpSession per iframe, it is - of course - mandatory that iframe 1 does not end up referencing httpSession state for iframe 2 instead of own. off top of my head I can think of: map page1 and page2 to different domains (ops overhead) use URL rewriting and never cookies (messes up analytics) anything else? thanks a lot, -nikita

  • Get UiBinder widget to display inline instead of block

    - by Steve Armstrong
    I'm trying to get my UiBinder-defined widget to display inline, but I can't. My current code is: <ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' xmlns:g='urn:import:com.google.gwt.user.client.ui'> <ui:style> .section { border: 1px solid #000000; width: 330px; padding: 5px; display: run-in; } </ui:style> <g:HTMLPanel> <div class="{style.section}"> <div ui:field="titleSpan" class="{style.title}" /> <div class="{style.contents}"> <g:VerticalPanel ui:field="messagesPanel" /> </div> </div> </g:HTMLPanel> </ui:UiBinder> This works fine in terms of how the widget looks internally, but I want to throw a bunch of these widgets into a FlowPanel and have them flow when the window is resized. The HTMLPanel is a div, but I can't get the display attribute to assign. I can't force the style name, since the following throws an error: <g:HTMLPanel styleNames="{style.section}"> And I can assign an additional style, but it doesn't apply the display setting. <g:HTMLPanel addStyleNames="{style.section}"> This displays the border and sets the size, as expected, but it doesn't flow. Firebug shows the styles on the div are border, width, and padding, but no display. Is there a way to make a widget in UiBinder so that it'll display inline instead of block? And if so, can I make it compatible with having a VerticalPanel inside (can I do it without making the entire widget pure HTML without any GWT widgets)? PS: I saw question 2257924 but it hasn't had any answers lately, and he seems to be focused on getting a tag, not specifically getting inline layout. I don't care directly about , if I can just get the top-level tag for my widget to flow inline, I'm happy.

For example, I want in the center region, one area which has room for one big widget, and then right below it, 2 areas for 2 smaller widgets. I keep trying to play with the columns to figure this out, but nothing seems to work. Help?

  • Saving State of Objects in GXT

    Is there a way to store the state of objects in GXT? That is, having a dynamically configurable GUI built in GXT, you can add your own widgets 'on-the-fly' in any order you like - with your own custom everything. Is there a way to save the state of all the objects, so one can load the profile back at a later date?

  • How to set android lock screen image

    - by robintw
    Hi, I'm just getting started with android programming, and want to see if there is a way to programmatically set the lock screen image. I've found various ways of setting the wallpaper in the API, but I can't seem to find the equivalent ways of setting the lock screen image. I've seen various posts saying that customising the lock screen by adding widgets or bits of applications is not possible, but surely there must be a way to set the image programmatically? Cheers, Robin
