  • QTWebkit 4.6 and ico images, Rendering problem

    - by Red Serpent
    Hi I have a local html file which I'm trying to view using QTWebKit, there are some images in the file which are of type ".ico" which seems that QTWebKit is not able to render them as it gives a question mark icon instead. I tried opening the html file in firefox and its working fine and all images gets rendered. My question is, does QTWebKit support ico images, and if it does... what should I do to enable webkit to render ico images? Regards

  • Django: Password protect photo url's?

    - by MikeN
    From my Django application I want to serve up secure photos. The photos are not for public consumption, I only want logged in users to have the ability to view them. I don't want to rely on obfuscated file id's (giving a photo a UUID of a long number) and count on that being hidden in my media folder. How would I store a photo securely on disk in my database and only stream it out to an authenticated session?

  • How to make the WebBrowser to scroll up when new content is appended to the bottom of the page?

    - by Java Doe
    In order to achieve this effect, I would like to know how I can make the WebBrowser to scroll up when new content is added to the HTML page? "Allow more entries to be displayed in the view: When the user clicks more, additional entries should be displayed in addition to the ones which are already displayed. The code should cause the UI to scroll such that the first entry of the "more" set is on top". I am using com.ibm.rcp.browser.service.WebBrowser which is similar to SWT WebBrowser.

  • Justifying UIVIews on the iPhone: Algorithm Help

    - by coneybeare
    I have been messing around with a way to justify align a collection of UIView subclasses within a containing view. I am having a little bit of trouble with the algorithm and was hoping someone could help spot my errors. Here is pseudocode of where I am now: // 1 see how many items there are int count = [items count]; // 2 figure out how much white space is left in the containing view float whitespace = [containingView width] - [items totalWidth]; // 3 Figure out the extra left margin to be applied to items[1] through items[count-1] float margin = whitespace/(count-1); // 4 Figure out the size of every subcontainer if it was evenly split float subcontainerWidth = [containingView width]/count; // 5 Apply the margin, starting at the second item for (int i = 1; i < [items count]; i++) { UIView *item = [items objectAtIndex:i]; [item setLeftMargin:(margin + i*subcontainerWidth)]; } The items do not appear to be evenly spaced here. Not even close. Where am I going wrong? Here is a shot of this algorithm in action: EDIT: The code above is pseudocode. I added the actual code here but it might not make sense if you are not familiar with the three20 project. @implementation TTTabStrip (JustifiedBarCategory) - (CGSize)layoutTabs { CGSize size = [super layoutTabs]; CGPoint contentOffset = _scrollView.contentOffset; _scrollView.frame = self.bounds; _scrollView.contentSize = CGSizeMake(size.width + kTabMargin, self.height); CGFloat contentWidth = size.width + kTabMargin; if (contentWidth < _scrollView.size.width) { // do the justify logic // see how many items there are int count = [_tabViews count]; // 2 figure out how much white space is left float whitespace = _scrollView.size.width - contentWidth; // 3 increase the margin on those items somehow to reflect. it should be (whitespace) / count-1 float margin = whitespace/(count-1); // 4 figure out starting point float itemWidth = (_scrollView.size.width-kTabMargin)/count; // apply the margin for (int i = 1; i < [_tabViews count]; i++) { TTTab *tab = [_tabViews objectAtIndex:i]; [tab setLeft:(margin + i*itemWidth)]; } } else { // do the normal, scrollbar logic _scrollView.contentOffset = contentOffset; } return size; } @end

  • Custom uitoolbar gets partly hidden

    - by Jakub
    I'd like to add a custom UIToolbar to my UIViewController. In Interface Builder I add the uitoolbar at the top of my view, and it looks just fine. However, when I run the app in the Simulator it gets hidden by the default iphone bar (this one with the clock, battery status, etc.). Here you can see how it looks like: Any ideas?

  • How to set the cursor in kEventControlSetCursor?

    - by fret
    I want to be able to change the appearance of the mouse cursor as it moves over various hot spots in my view's and it seems to me that I should be doing that in the kEventControlSetCursor handler (which I can get). The function "SetCursor" is deprecated, which leads to the question, what do I call to actually change the cursor? And is there some standard list of cursors I can use? Things like horizontal and vertical arrows? I beam?

  • Add querystring parameters to link_to

    - by Craig
    I'm having difficultly adding querystring parameters to link_to UrlHelper. I have an Index view, for example, that has UI elements for sorting, filtering, and pagination (via will_paginate). The will_paginate plugin manages the intra-page persistence of querystring parameters correctly. Is there an automatic mechanism to add the querystring parameters to a give named route, or do I need to do so manually? A great deal of research on this seemingly simple construct has left me clueless.

    From within TFS 2008, is there a way to view the disk space taken up on the server by a project (or by all projects)? Or is this something that can only be done by looking directly at the underlying database?

  • Display SharePoint lookup field on publishing website

    - by Slace
    A page within our MOSS publishing website has a property which is a lookup field. I only want the selected text to be displayed when you view the page not in edit mode, but when I use the Microsoft.SharePoint.WebControls.LookupField it generates a hyperlink to the SharePoint list item (obviously bad). Is there a way around this, short of creating my own lookup field control?

  • UIViewController rotate methods

    - by Corey Floyd
    What object is responsible for dipatching the UIViewController rotation method calls, i.e: – shouldAutorotateToInterfaceOrientation: – willRotateToInterfaceOrientation:duration: – willAnimateFirstHalfOfRotationToInterfaceOrientation:duration: – willAnimateSecondHalfOfRotationFromInterfaceOrientation:duration: – didRotateFromInterfaceOrientation: I imagine it is UIApplication (but maybe the AppDelegate or UIWindow). The next question, is how does the object know which UIViewController to talk to? How does it know which UIViewController has its view as the subview of the window? Is there a message you can send or a property you can set (of some object) that sets the "Active" UIViewController for the app?

  • Which run-time charting tools produce the best time axes?

    - by eft
    I need to generate and embed a time series chart into an ASP.NET application. Most run-time charting tools generate poor time axes, especially if the time scale is dynamic ie the user may choose to view data over a time scale of days, weeks, months or years. I'm looking for recommended tools that can be integrated into my app. Two that show promise are Chart Director and Google's annotated timeline visualization. Both are quite different in their implementation and have pros/cons.

  • Non RBAC User Roles and Permissions System: a role with properties

    - by micha12
    We are currently designing a User Roles and Permissions System in our web application (ASP.NET), and it seems that we have several cases that do no fit within the classical Role-Based Access Control (RBAC). I will post several questions, each devoted to a particular case. This is my second question (the first question is here: http://stackoverflow.com/questions/2839797/non-rbac-user-roles-and-permissions-system-checking-the-users-city). We have the following case: we need to implement a Manager role in our web application. However, a Manager can belong to one or several companies (within a big group of companies for which we are creating this web app). Say, there can be “Manager of companies A and B”, “Manager of company C”, etc. Depending on the companies that the Manager belongs, he has access to certain operations: for example, he can communicate with clients only of those companies that he belongs to. That is, “Manager of companies A and B” can only have contacts with clients of companies A and B, and not with those of company C. He can also view clients’ details pages of companies A and B and not of C, etc. It seems that this case falls within the RBAC. However, this is not really the case. We will need to create a ManagerRole class that will have a Companies property – that is, this will not be just a role as a collection of permissions (like in the classical RBAC), but a role with properties! This was just one example of a role having properties. There will be others: for example, an Administrator role that will also belong to a number of companies and will also have other custom properties. This means that we will a hierarchy or roles classes: class Role – base class class ManagerRole : Role List Companies class AdministratorRole : Role List Companies Other properties We investigated pure RBAC and its implementation in several systems, and found no systems featuring a hierarchy or roles, each having custom properties. In RBAC, roles are just collections of permissions. We could model our cases using permission with properties, like ManagerPermission, AdministratorPermission, but this has a lot of drawbacks, the main being that we will not be able to assign a role like “Manager of Companies A and B” to a user directly, but will have to create a role containing a ManagerPermission for companies A and B… Moreover, a "Manager" seems to be rather a "role" (position in the company) rather than a "permission" from the linguistic point of view. Would be grateful for any ideas on this subject, as well as any experience in this field! Thank you.

  • How to add XML elements into the toolbox in Visual Studio 2010 RC

    - by Alex Marshall
    I'm trying to edit an XML schema in Visual Studio 2010 Ultimate RC, but when I go to the toolbox (with the schema open and focused) there's absolutely nothing in the Toolbox view, even when every tutorial out there that I've read tells me that there should be. I've tried using the context menu option for resetting the Toolbox to no effect. Is there something I'm missing ? Something I need to install to get this feature of Visual Studio going ?

  • TreeView Root Node Style

    - by ScG
    I have a tree view <asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1" ShowExpandCollapse="False"> </asp:TreeView> As you can see, root node is hidden. However when the treenode gets rendered, there is a whitespace to the left of each leafnode. This is probably because the root node is hidden but is taking up space. How do i remove that white space.
