Is there a widget for GTK or Qt that would allow me to draw stock charts like this?

Thanks, Joel
Qwt can handle it and Uwe Rathmann the main developer is active and helpfull

How about GTKGraph? Or see if you can pull something out of Grism? The author writes:
I draw stock charts using a
GtkDrawingArea and a Cairo context.
The charts are not animated, but if
you resize the chart window, the chart
automatically resizes (actually, it
performs a redraw).
There's KD Chart for Qt.
Try this: NightCharts.
But you should keep in mind, that it's a self-made thing without any support and seemingly its development has been stopped already. So probably there may be a plenty of bugs.
And one more thing. IMHO it draws the most pretty pie charts among other Qt chart libraries.
Medsphere has made their graphing widget available, note that it's implemented in gtk# though.

Which is a better interface for designing an ASP.net application: drag and drop or manual positioning?
That defines on how you define "better".
"Better" in the sense that even an unskilled developer can get a webform up and running in no time: Use drag and drop.
"Better" in the sense that it gives a skilled developer more control over the generated HTML and CSS, potentially leading to
more robust layouting, compatible with a wide range of browsers, and
easier maintainance, due to a lack of unnecessary tags and attributes:
Use manual positioning and a lot of knowledge about HTML and CSS.
You use them all - anything to make the design you look for.
Drag Drop, Manual position, tweak changes, css write/change/delete/re-write, copy/paste, open close ten programs, search on google for other css, anything to make what you have on paper - and then is not good and you start over. Anything you can have you use it.

I need to develop a web application in asp.net which needs to display
-bar charts
-pie charts,
-gauges,
-grids
with HTML 5 support. And able to export the content in PDF format.
As a winforms developer im not familiar with web technologies.
I have found these componenets
-Telerik web charts-- i didn't see gauge control
-Devxpress-- no info about HTML 5 support
-Kendo UI-- low export functionality
Could you please advise some other components or comment these to help me selecet proper one?
many thanks.
I had the same requirements (except that the backend technology could be whatever I wanted) and ended up creating the charts as images on the server. A bit memory intensive, but worked exceptionally well. I also created an old-fashioined image map to facilitate context-aware mouseover popups on the client.
The main reason I did it that way was, that whatever I tried, there was never a perfect fit between the chart as shown in the brwoser (with the added layer of difficulty that user could use whatever brwoser they wanted) and the PDF. Images ofcourse solved that.

I've been using Paint.NET to create mockups for my web application. They're pretty, and it's not hard to save the constituent graphical elements. However, the process of getting my layout into CSS is completely manual and time-consuming.
I'm aware there are better tools out there for this. Should I be looking at DreamWeaver? I'm not looking for any auto-generated web or data access functionality, and I'm happy to code all the behavior myself. I'm mostly looking for a great-looking layout editor that understands both layered imaging and CSS. (Preferably, one that can map a layered image to HTML and generate initial CSS with the right styling.)
Thanks in advance for any and all insight!

A text editor, really.
It's time consuming, yes, but so is doing anything right. I have yet to use any program that builds the design of a website with a level of markup quality that I find even remotely acceptable. Where you may give a div a class of userInfo, most layout programs might give that div a class of style12 or something equally unhelpful. This results in unmaintainable markup, which is especially hard to build into a web application.
So learn how to do it by hand, and then do it by hand.
Axuer can be used to take mockups/prototypes and export as HTML/CSS: http://www.axure.com/
I only ever used it for prototyping.
There are no apps that will make it a css3, they apps that exist will give you a lot of image sprites and css2 and a lot of bugs you have to fix manually :/
So suggest coding it manually or hiring someone who does it(Kinda cheap these days even I would do it if I get paid well enough)

I'd like to build a dashboard interface for an application I am working on. I want users to logon and get a birds eye view of the status of applications, outstanding issues, etc. I'm wondering if there are some good, pre-made controls rather than writing these from the ground up?
You could look at Telerik's RadDock control for ASP.NET AJAX. It is not free ;)
For graphs and charts I would first try out the built in charting library in Visual Studio 2010.
If you cant use 2010 (even the express edition) for some reason then look at the charting controls for VS2008 MS Charting

I'm quite new to this mobile development. I just download the Qt SDK from the Nokia web site.
My background is C,C++ and I am not very familiar with the visual/IDE kind of stuff. Normally I do things using the console and the vi editor, etc. I have been spending almost 10 years of development mainly on web applications (PHP/Python/Flex/ActionScript/JavaScript/C/etc).
I am interested in jumping into this new wagon, of applications for mobiles. I need some guide to start with, any references such online documents/readings/examples or books for a starter like me.
There is a official Qt book here. There are also other good books you can check out. You can find one that best suits your needs, given the background you came from and the knowledge you possess.
This would be a good site if you want to get started right away.
