I have a question regarding a platform I'm developing called e-cidadania (GPL). One of the applications will be something like a blackboard where you can put messages. I've been requested to do it like a cartesian grid (p.e. x = good/bad, y = expensive/cheap). My question is, does anybody know about an application like that for django? Or in case that there isn't, how can I do it? I have no idea where to start.
I'll explain a use case, if someone didn't understand: You are in a classroom, the teacher draws on the blackboard the axis and tells the students to write a note. After that every student will put his note according to the axis.
I am not sure if I completely understand your question, but if I'm correct you want the user to input text (name of restaurant or something like that) and instead of showing 2 sliders or dropdown boxes for rating and price, you want to show a cartesian chart where the user can click somewhere, thus entering the 2 values with one click.
This has nothing to do with Django or Python, this is pure client side. Think javascript. One way is to show an image with the cartesian grid, set an onclick handler and see where in the image the click was made. Showing the selected point could be done simply by setting a colored div with an absolute position (relative on the position of the image).
I don't know any plug-and-play solutions, but building this shouldn't be too hard.
On a separate note: I doubt this will actually be more userfriendly for the user then simply using two sliders.
Update:
Or if you want to show a big cartesian chart where the user actually has to input the text on the correct position, this can be done with the same idea: create the text-input, but hide it (display:none). Then when the user clicks somewhere on the chart, move the text-input to the correct position and show it.
This may be a little far fetched, but instead of doing this with django alone, why dont u do this client side using javascript?
Hear me out here.
The highcharts graphing plugin has an option that allows u to add points on a (cartesian) graph. Check this example. The plugin also allows you to display custom messages when hovering on points, so you could use that to display the actual message, and you could handle the actual saving of the new message by submitting the newly added message via Ajax.

I'm using REDMINE.
I have a list of projects on the screen.
Is it possible to add details of the ticket content to this screen?
I'd like to look over the screen at once instead of clicking with the mouse, how do I do that?
Also, if you have any plugins or useful tips and so on, please let me know.
Tamazawa, I believe you might be referring to "My Page" of Redmine where you could use widgets to decide what you see on that dashboard - keep in mind that such dashboard s project independent, so it can display issues from many projects that you are a member of on 1 screen.
For instance from My Page, you should be able to select an "Issues" widget to Add and set it up to pull a list of items to display using a saved custom query.
That should give you a snapshot of tasks at hand, without the need to click around the screen too much.
You may need to set up your saved query such that:
Description and / or
Last notes
are checked (if you want to see issues at a glance, without the need to open each one separately).
Alternatively, you can skip that "My Page" idea altogether, if you're ok with just opening a saved query with Description and / or Last notes selected.
So im building a basic win32 GUI app and I have a vector of data that gets constantly updated through an external source via a port. Im interested in displaying that list of data to the user but im not sure the best approach to go about it without causing update flickering.
I originally had an edit box in which I build a string with the information and update the window. But it has proved troublesome as the amount of data grows since I cant scroll down to look at additional data. Any ideas?
My idea is no point of updating the visual control as the same speed you receive the data. Because even-though you update at the same speed the users cannot see that change at the speed of data receiving. Human eye does not see a change happening in speed as 1/8th of a second. So better to update the visual control in a controlled manner. Maybe using a timer.
Appending to the text of an edit control for each subsequent data point will lead to flickering as the whole control re-renders as the text has changed.
I'd advise one of the following options:
1) use a ListBox or ListView control; when you add another row item, it only re-draws the new/changed/scrolled item. https://learn.microsoft.com/en-us/windows/desktop/controls/create-a-simple-list-box and https://learn.microsoft.com/en-us/windows/desktop/controls/list-view-controls-overview
2) If you only want an always-scrolling list of data, consider just having a command-line application that writes to the standard output and saves you a lot of trouble - cout or printf your data.
You can also use EM_SETSEL and EM_SCROLLCARET to automatically scroll, but also check the position of the scroll bar before doing that. If not at the bottom, it means that the user wanted to pause, so you can scroll.
Also, you can have the scroll lock key checked in order whether to scroll or not, after all that is what it's name is supposed to do.
I have an unusual request from a client as follows:-
The customer has selected a specific colour (by layered nav) however this colour is NOT the colour assigned to the configurable option. An example here. Customer picks red but this could be red, dark red or burgandy. I would then need to show 3 copies of this product with the correct colour selected to show for the media portion of the list object.
I have extended the Product_list block and added a function called getColourProductCollection() which is an extension of the _getProductCollection() function. the attributes are filter_colour (the one shown on the layered nav (primary colour) and the configurable attribute is called config_colour (secondary / real colour).
I realise this is going to be a fair amount of work but this is a feature my client is insisting on moving forward. The code i have is working and my extended function is being called (and is currently returning the normal collection). I could build this with an object by looping over all products finding the children and adding any which have the correct primary colour attribute. my question however is how to return this as a collection as is the case with the getLoadedProductCollection() function call? Handling the image swapping code is already pretty much implemented provided i have a collection returned to fit in with existing list template.
Thanks in advance for any suggestions or pointers here.
p.s. i found this page http://www.blog.magepsycho.com/how-to-convert-an-array-to-a-collection-object-in-magento/ which would allow me to create and add each item. Would this be a good way to proceed here?
p.p.s. After looking further into adding manually (the above p.s.) i realise that the moment i add the same product again it wont add it to the collection.
I've been following YouTube tutorials most of the day now and I think I've got the basic hang of forms. I'm aiming to create something like this below, which checks a users password and shows how strong it is:
This is what I have at the moment:
I'd like to know the basic theory behind how the top form works, specifically how I can take the user input of password in my form and just get it to print and update in realtime underneath below. I'm not quite sure what tool is used to do that, or for that matter what tool is used to create the colour changing box.
Any help or direction is appreciated, thanks!
Add a keyboardListener to your jtextfield. When a key is pressed get the text and do your stuff(figure out the strength, number of Uppercase etc)
Is this win32 or mfc forms, or some other tech like Qt or wxWidgets?
In both cases you will want to handle messages from the edit field as text is changed in it. This message is the EN_CHANGE message. Handle that message and you can get the text from the edit field and send messages to the strength form to tell it to change its color and text.
Add a System::Windows::Forms::KeyPressEventHandler (or similar) to the TextBox. When raised, do whatever analysis you need to do on the string and update the table below. The color changing box can be one of many implementations. It can be something as simple as a panel that changes its background with a System::Windows::Forms::Label positioned on top of it. It actually looks like that, as the text is not centered.
I need to create a European map with raphael.js.When mouse over on it,it should display the country name.I don know whether raphael itself form a MAP with the points else do we have to have a map.I really dont have any idea,Please help me on this.I tried looking at the site http://playground.mobily.pl/tutorials/building-an-interactive-map-with-raphael/demo.html,it says something like SVG.Where should I declare that in javascript.
Can anyone help me with this how can i start up or some clear idea.
You do need the contour of every country in SVG format and all of those should be in the same coordinate system, of course.
If you check the source of the page you refer to, it references a javascript file that contains those paths.
