I am new to TurboGears2 and by extension ToscaWidgets2. I am following the tutorial given here http://turbogears.readthedocs.org/en/latest/cookbook/datagrid.html
for creating a basic datagrid. When I view the index page, all I see is this:
class 'tw2.core.params.DataGrid_s_s'
I have also tried using a DataGrid for showing data from an existing DB, but I also get the same above result. Shouldn't there be a .css file that would handle the grid generation/display?
I have checked past tutorials for using DataGrid on TurboGears, and when it comes to displaying the grid, they only show this line:
${grid(value=data} ( or ${grid(data)} in older TG versions).
Since there are no errors being shown, I am at a complete loss here. I have searched online for a solution on this, but I haven't been lucky. Any advice on how to get around this?
Cheers,
DM
It changed in recent ToscaWidgets versions, when you want to display a widget (like the DataGrid) you should prefer an explicit call to the display method instead of calling the widget itself.
try to replace ${grid(value=data} with ${grid.display(value=data}
Have a look at the Forms tutorial, it covers some basics on working with forms and TW2 widgets, the DataGrid in the ends it's just a Widget so behaves like forms for some features.

All,
I am trying to use syncfusion data grid in xamarin forms now.I have installed trial version as of now. I have created demo from this link
All is fine.I have added all references,no errors at all. but it doesn't shows the datagrid in output( i am using vs inbuilt emulator).it just shows the blank screen like
I couldn't find anything wrong what I have done in my code from above link.its really simple but still why I am not getting output.please help.
Thanks in advance
If you load SfDataGrid directly as a child, the grid will be loaded. If you want to load SfDataGrid inside a ScrollView or a StackLayout, refer the below UG link to achieve it,
https://help.syncfusion.com/xamarin/sfdatagrid/getting-started#launching-the-sfdatagrid-inside-a-stacklayout
Also, you can refer our KB link below to achieve your requirement.

Is there a way via extendscript (jsx) to get the visibility status of Photoshop' guides?
The code to show and hide the guides is the same code as it 'toggles' the guides on or off so it must know the status when this code is executed, but how do I get at it?
I appreciate this could be done via a preference switch but that seems an awkward hack for something this simple, especially as something somewhere must be accessing this 'property' during execution of the 'toggle' code.
What would be great is to have activeDocument.guides.visible property, returning either true or false. Is there anything like that?
EDIT:
OK. Further investigation reveals that creating a guide using guides.add does not automatically toggle guides ON, however, using the code generated via the scriptListener does.
I would rather use guides.add as its only one line of code compared to fourteen so in order to toggle the guides to ON I thought I could run a function that created and then deleted a guide using the scriptListener code during the onLoad of the HTML.
This works great, except getting this function to run only when a document is opened is now the new problem.
documentAfterActivate is supposed to be the code to do this except it doesn't work unless a flash panel such as kuler is opened first.
So the question now is really what part of the flash code is allowing documentAfterActivate to work properly and how can I use it in my code instead of opening a flash panel I don't need?
It doesn't look like you've got a direct toggle option. You'd need to record the position of the guides somewhere and use script listener code to clear them when you wanted to toggle them off and use the add method on the Guides object to re-add them.
Keep in mind that even getting to the guide position via the photoshop DOM wasn't avail before CS4 I think? maybe CS5.
And i realised I just mis-read your question quite a bit. Anyway, this way you'd also know if the guides were visible based on whether or not they are there :) But yes, it isn't as nice as it could be.
The solution:
As stated, the workaround is to create and delete a guide with the fourteen lines of code from the scriptListener.
This toggles the guide visibility to ON regardless of its current state.
I can then save this status as a preference using putCustomOptions.
A function to do this is fired during the onLoad of the HTML but only when a document is opened otherwise guide creation fails.
documentAfterActivate does not work as expected unless a further flash panel (such as Kuler) is also opened beforehand.
An alternative to documentAfterActivate is to register the open event using CSevent instead.
The code can be found HERE.
I am trying to set up functionality similar to Netflix. Where if you mouseover a movie - you are presented with a window of movie details (all client-side).
At high level, can someone in this forum help by telling me how this should be implemented? I.E., one or more .aspx pages, what would go in code-behind, and .js file, css, etc. Just trying to get an idea on how this would be set up to work.
Basically, when I hover over an item, I need to query for details that belongs for that record being moused-over and display it in the window or div. I also need to have some functionality in that window (i.e. a textbox and button which will end up needing to get saved in a database).
Thanks for any tips and suggestions -
You would want to add an AJAX call to the hover event of the image, that pulls from a webservice/web method.
Here is a good example, you would change some things. However, it should get you started.

If I understood your question correctly, you should try this excelent jQuery plugin:
http://www.sohtanaka.com/web-design/css-on-hover-image-captions/
Look at the demo here:
http://www.sohtanaka.com/web-design/examples/image-hover/
easy to install and configure and very slick!
Good luck
EDIT: sorry wrong lik the first time
There are certainly many jQuery plugins that will do this for you. jQuery UI may also be of benefit.
Here is one that appears to do something like you are describing:
http://plugins.jquery.com/project/VisualLightbox
I am going to write an application that uses QT4 (with C++ or python it isnt important in that moment).
One of functionality is "Showing all items in database".
One item has a Title, author, description and photo (constant size)
And there could be very many items. Let's say 400. There won't be enough space to show'em all at once time.
One row will have 200px, so i need at most 4 for once time.
How to paginate them? I have no idea.
I can use limit and offset in SQL queries, but how to tell window: "that's 5th page"?
Any solutions?
First off, you normally do not want to use any manually set pixel widths in any GUI application, if you do, your toolkit sucks (or you must work in game development).
Second off: be more specific.
You'll need to define "page" for your application, namely what a page should be in its context. I assume it is breaking a list of items into separate pages. Normally this is done by using one of the view classes (e.g. QListView or QTableView) to take care of much of the legwork: it's called a scrollbar (not to mention the collapsing folders concept from file managers). Another method is splitting the information across several tab pages (QTabWidget), where each page displays a view of some sort (Perhaps QTextView or one of the M/V or Item view classes).
Same thing can also be done using your own widget stack and some other widget to manipulate the currently displayed page. This is basically how the option dialogs in the TeamSpeak 3 client and most KDE apps work; it's also how wizards with back/next buttons work in concept. I suggest you take a look at this config dialog example
Normally what you want is a view with a scrollbar and or some form of collapsing related entries into categorised information. If you just want to display a list of pages where each page is X entries: use a tab widget or stacked widget.
How do I switch between the two screens on the Qt?
For example, I have a button - static text plus a toolbar. Now I will add it to a frame and set it as a central widget. It works well for one window. What if I move it to the next window? Then I need to show some other stuff like another button, some images etc... and what if I come back to the first view again?
How do I show my old widgets back?
I'm not sure I got your problem right but, you could have different scenarios :
You could simply use groupboxes... Some widgets in groupbox1, otherWidget in groupbox2, and you display the groupbox you want to use, hiding the others...
You could use stackedWidget, which simulates "pages" of widgets stacked on top of eachothers... more informations here : http://qt.nokia.com/doc/4.6/qstackedwidget.html.
You could use other way like using tabs : http://doc.trolltech.com/4.6/qtabwidget.html
Maybe this example would be useful to you : http://qt.nokia.com/doc/4.6/dialogs-configdialog.html
Hope it helps a bit !
I'd recommend checking out Animation/States example (should be in /qt/examples/animation/states/ subdirectory of your Qt installation). It shows how to combine state machine representing application logic with presentation layer and get cool animation effects for free (of course if you don't need eye candy, you can set widgets properties without any animation).
