    Hi all I have to do a little script in Python. In this script I have a variable (that represents a coordinate) that is continuously updated to a new value. So I have to draw a red point over a image and update the point position every time the variable that contains the coordinate is updated. I tried to explain what I need doing something like this but obviously it doesn't works: import Tkinter, Image, ImageDraw, ImageTk i=0 root = Tkinter.Tk() im = Image.open("img.jpg") root.geometry("%dx%d" % (im.size[0], im.size[1])) while True: draw = ImageDraw.Draw(im) draw.ellipse((i, 0, 10, 10), fill=(255, 0, 0)) pi = ImageTk.PhotoImage(im) label = Tkinter.Label(root, image=pi) label.place(x=0, y=0, width=im.size[0], height=im.size[1]) i+=1 del draw someone may help me please? thanks very much!

  • UISearchBar in UINavigationBar with ScopeBar

    - by ncipollina
    I am trying to put a UISearchBar inside of the UINavigationBar, which I am able to do without much problem. The problem is that I have logic when editing to show the Scope Bar. This all works fine, with one exception. The navigation bar tries to center the UISearchBar inside of the title view. This causes the search bar to move up above the navigation bar. I tried adding some logic to set the frame of the search bar so that it just draws overtop of my main view, which is fine. I can only set the height, which causes the search bar to draw over the view just fine, but it isn't wide enough to cover the whole screen. If I set the width on the frame, it goes back to the same behavior of trying to center the UISearchBar on the navigation bar. Anyone know how I can accomplish this? Thanks, Nick

  • Python/Tkinter make a custom window

    - by user1435947
    I want to make a window without the top taskbar (that is movable), so there is only thin outline around the GUI box. I also want to add my own 'X' to the box. import Tkinter class Application(Frame): def __init__(self, master=None): Frame.__init__(self, master) self.parent = master ............ def main(): root = Tk() root.attributes('-fullscreen', True) root.geometry('500x250+500+200') app = Application(root) app.parent.configure(background = 'gray32') root.resizable(width=FALSE, height=FALSE) app.mainloop() main() I tried forcing the box to resize after going into fullscreen to remove the taskbar, though box is no longer movable. Any suggestions? [I have seen this thread: Python/Tkinter: Removing/disabling a resizable window's maximize button under Windows The -toolwindow attribute didn't work for me, maybe because I use linux...]

  • Have to put files in static_dir but need to read them afterwards

    - by SanjamX
    I just started using google app engine. In order to use templates, I'm using jinja2. I want to add images dynamically after I set the width and height of the img tag. I used PIL in order to read the image size and put the one I want. However when I open the image with PIL, I need it not to be in a static_dir and to put the image in the img tag, I need it to be in the static_dir. As a testing solution I've copied the folder to see if I get results and I did. But as you can see having each image saved twice is kind of bad.

  • Better ways to print out column names when using cx_Oracle

    - by philipjkim
    Found an example using cx_Oracle, this example shows all the information of Cursor.description. import cx_Oracle from pprint import pprint connection = cx_Oracle.Connection("%s/%s@%s" % (dbuser, dbpasswd, oracle_sid)) cursor = cx_Oracle.Cursor(connection) sql = "SELECT * FROM your_table" cursor.execute(sql) data = cursor.fetchall() print "(name, type_code, display_size, internal_size, precision, scale, null_ok)" pprint(cursor.description) pprint(data) cursor.close() connection.close() What I wanted to see was the list of Cursor.description[0](name), so I changed the code: import cx_Oracle import pprint connection = cx_Oracle.Connection("%s/%s@%s" % (dbuser, dbpasswd, oracle_sid)) cursor = cx_Oracle.Cursor(connection) sql = "SELECT * FROM your_table" cursor.execute(sql) data = cursor.fetchall() col_names = [] for i in range(0, len(cursor.description)): col_names.append(cursor.description[i][0]) pp = pprint.PrettyPrinter(width=1024) pp.pprint(col_names) pp.pprint(data) cursor.close() connection.close() I think there will be better ways to print out the names of columns. Please get me alternatives to the Python beginner. :-)

  • Custom cell and Delete/Move indicators

    - by Kamchatka
    Hello, I have a custom UITableViewCell. However, when I got in edit mode, I don't have any Delete and Move indicators appearing. The custom cell draws itself in the contentView. In layoutSubviews, I make sure there is space on the left and one the right of the contentView so that the controls can appear (if this was the problem). - (void)layoutSubviews { self.contentView.frame = CGRectMake(50, 0, self.frame.size.width - 100, sub.thumbnail.size.height + 20); } In the UITableViewController, I return YES in: - (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath { How could I solve this lack of interactivity. Is there something specific for custom cells? Thanks!

  • ggplot add percentage labels based on x-axis variables

    - by eugeneyan
    I've a ggplot that shows the counts of tweets for some brands as well as a label for the overall percentage. This was done with much help from this link: ggplot: showing % instead of counts in charts of categorical variables # plot ggplot of brands ggplot(data = test, aes(x = brand, fill = brand)) + geom_bar() + stat_bin(aes(label = sprintf("%.02f %%", ..count../sum(..count..)*100)), geom = 'text', vjust = -0.3) Next, I would like to plot it based on brand and sentiment, with the labels for the bars of each brand totalling up to 100%. However, I have difficulty amending my code to do this. Would you be able to help please? Also, would it be possible to change the colours for neu to blue and pos to green? # plot ggplot of brands and sentiment ggplot(data = test, aes(x = brand, fill = factor(sentiment))) + geom_bar(position = 'dodge') + stat_bin(aes(label = sprintf("%.02f %%", ..count../sum(..count..)*100)), geom = 'text', position = position_dodge(width = 0.9), vjust=-0.3)

  • WPF: How to efficiently update an Image 30 times per second

    - by John
    Hello, I'm writing a WPF application that uses a component, and this component returns a pointer (IntPtr) to pixels of a bitmap (stride * height). I know in advance that the bitmap is a 24bits rgb, its width and height. Updating the Image control with these bitmaps makes up a video to the user, but I'm not sure what's the most efficient way to do that, most of the time the CPU usage goes to 75%+ and memory changing from 40mb to 500mb and the nI think GC starts to work and then it drops again to 40mm. The app starts to not be responsive. What shoud I do? thanks!

  • Actionscript 3 svg XML parsing bug?

    - by Mahir
    Hey I get two different results when using the for each loop below.

  • Floating images with multiple sizes in CSS

    - by Jamie Chapman
    I'm wanting to be able to create a banner of floating images based on what are uploaded via users. The tool needs to have images of 50x50 and 100x100. At the moment, I just want to randomly display the images and tried to apply float:left. However, as you can see below - it leaves gaps. Is there an easy way to do this without programatically positioning the images? If you want the code so far, it's here: .wall { width: 300px; background-color: red; display: table; } .wall img { float: left; } and <div class="wall"> <img src="man1.png" alt=""/> <!-- ETC... !--> </div>

  • Resizing an image with alpha channel

    - by Hafthor
    I am writing some code to generate images - essentially I have a source image that is large and includes transparent regions. I use GDI+ to open that image and add additional objects. What I want to do next is to save this new image much smaller, so I used the Bitmap constructor that takes a source Image object and a height and width, then saved that. I was expecting the alpha channel to be smoothed like the color channels, but this did not happen -- it did result in a couple of semitransparent pixels, but overall it is very blocky. What gives? Using img As New Bitmap("source100x100.png") ''// Drawing stuff Using simg As New Bitmap(img, 20, 20) simg.Save("target20x20.png") End Using End Using Edit: I think what I want is SuperSampling, like what Paint.NET does when set to "Best Quality"

  • I just don't know what it is, tried everything, IE 7 bug

    - by Emmy
    Has anyone seen this bug? I have a sidebar with a ul nav background image for the hover state, floated right, looks great in all browsers. Then...I added another div underneath it for ad space. inside, there's an anchored image. That image tucks underneath the background image of the nav, but only in IE7 (i abandoned trying to please ie6). So I took it out of the sidebar, played with float, display,height hacks, but nothing works I can declare a large top margin with some more top padding do get it to clear but it breaks the design. i even tried creating a div called clear and put a top margin there. so it displays with this huge gap in chrome, FF, safari but this tiny space between in IE. i even tried creating a div called clear and put a top margin there. I have spent hours trying to find someone with the same problem but to no avail. Any suggestions? Here's a code snippet: <div id="leftsidebar"> <div id="leftnav"> <ul class="slidenav" id="sidenav"> <li id="overview" class="inactive"> <a href="expat.html">expat lifestyle</a> </li> <li id="tips" class="inactive"> <a href="traveltips.html">travel tips</a> </li> <li id="bts" class="inactive"> <a href="bts-mrt.html">bts/mrt</a> </li> <li id="bus" class="inactive"> <a href="bus.html">bus system</a> </li> <li id="van" class="inactive"> <a href="taxi.html">vans/taxis</a> </li> <li id="boat" class="inactive"> <a href="klong.html">boats/klong</a> </li> <li id="boat" class="inactive"> <a href="klong.html">boats/klong</a> </li> <li id="tuk" class="inactive"> <a href="tuk.html">tuk-tuks</a> </li> <li id="train" class="inactive"> <a href="train.html">trains</a> </li> <li id="airport" class="inactive"> <a href="airport.html">int'l airport</a> </li> <li id="dangers" class="inactive"> <a href="dangers.html">dangers</a> </li> <li id="fun" class="inactive"> <a href="fun.html">fun places</a> </li> <li id="shopping" class="inactive"> <a href="shopping.html">shopping</a> </li> </ul> </div> </div> <div id="store"> <a href="astore.amazon.com/ten044-20"; title="Shop WIB store"> <img src="images/WIBstore.png" height="70" width="200" border="none"/> </a> </div> the corresponding CSS: #leftsidebar { float:right; width: 210px; margin: 40px 0 0 0; padding: 0; height:1%; } #store { margin: 20px 0px 0 0px; padding: 0 10px 0 0; float: right; height: 1%; display: inline; } And an image:

  • Can't get ellipsis to work on Android

    - by Mark
    Hi, I have a TextView. I want it to ellipsize if longer than its available width. This does not work unless the input string has no spaces... can anyone provide an example of this working? I've tried different combinations of: singleLine="true" maxLines="1" scrollHorizontally="false" none of these have any effect. Again, if I supply a string that has no spaces in it, then the ellipsis appears correctly. What am I missing? I've tried this on 1.5, 1.6, 2.0, all same problem. Thanks

  • Toastr.js notifications as modal notfication

    - by Maxsteel
    I know it's not what toastr (or toast notifs in general) are meant to be used for, but I want to use them as a modal notification. My idea is following. On toast show: toastr.options.onShown = function() { //Create an overlay on the entire page} Overlay: #overlay { background-color: rgba(0, 0, 0, 0.8); z-index: 999; position: absolute; left: 0; top: 0; width: 100%; height: 100%; display: none; } And on toast close: toastr.options.onHidden = function() { //make overlay go away } Also, I'm setting timeout of toast to 0 so it won't disappear by itself. Question: I want the toast notification to stay atop the overlay and not behind it as overlay will cover everything. How can I do it?

  • generate Grid from template

    - by theXs
    Howdy, I've got another question regarding phone 7... I want to generate a couple of Grids in a stackpanel - since they all have the same layout I thought it would be a great idea to use DataTemplates ... But then I found that the GRID Object has no "DataTemplate" Property and now I'm kinda stuck ... the template which I use is the following: <DataTemplate x:Key="Speise"> <Grid> <TextBlock Height="36" Margin="8,43,104,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top"/> <TextBlock HorizontalAlignment="Right" Height="36" Margin="0,44,8,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top" Width="92"/> </Grid> </DataTemplate> The way I now thought of creating my objects is: Grid blubber = (Grid)this.Resources["Speise"]; But that is not working ... I think it's again a really short thing, but I have no clue of how to google for it :(
