• How to draw a line between two buttons?

  Hello.

  I want to do two mobile buttons attached to a line. When changing the position of any button you change in the appearance of the line of course.  I know how to draw a line, but after MOUSE_DOWN and I don't know how to remove an old monotube and how this line to appear all the time?

  My code

  btn2.addEventListener (MouseEvent.MOUSE_DOWN,
  mouseDownHandler3);
  btn2.addEventListener (MouseEvent.MOUSE_UP, mouseUpHandler3);
  btn3.addEventListener (MouseEvent.MOUSE_DOWN, mouseDownHandler3);
  btn3.addEventListener (MouseEvent.MOUSE_UP, mouseUpHandler3);
  
  Set a mouse down Manager (the user is dragging)
  function mouseDownHandler3(evt:MouseEvent):void {}
  var object = evt.target;
  We have to limit them by dragging to the area inside the canvas
  object.startDrag ();
  }
  function mouseUpHandler3(evt:MouseEvent):void {}
  var obj = evt.target;
  obj.stopDrag ();
  spisujemy x, y
  var x2Pos:Number = btn2.x;
  var y2Pos:Number = btn2.y;
  var x3Pos:Number = btn3.x;
  var y3Pos:Number = btn3.y;
  trace (x3Pos);
  trace (y3Pos);
  var roundObject:Shape = new Shape();
  roundObject.graphics.lineStyle (2, 0 x 990000,. 75);
  roundObject.graphics.moveTo (x2Pos, y2Pos);
  roundObject.graphics.lineTo (x3Pos, y3Pos);
  this.addChild (roundObject);
  this.removeChild (this.getChildAt (this.numChildren-1));
  }

  Here is a solution that you can adapt for two or more buttons...

  for (var i = 0; i)
  inclinometer [i] .buttonMode = true;

• Draw a line connecting two points in the WPF chart

  I'm trying to understand the best way to draw a line between two existing points on my graph in WPF.  At first, I thought I had it works fine; I just added another parcel to my graph then given exactly two points for rendering.  But I quickly noticed that the app has become surprisingly slow and CPU was quite high (adding other plots does not affect the use of the CPU as long as they have a complete set of points (?)).  He wants me if I looked at using the DataToScreen method on the chart but I can't know what the parameters are.  The second parameter is simply an IList that tells me a lot.  This seems to be the method I want to use for the coordinates of a point on the graph screen.

  No one knows what the second parameter is supposed to be for the DataToScreen method?  Everything I tried throws an Exception of Argument.

  Thank you
  Dan

  DataToScreenwill return a screen coordinate in the plot area of a chart of the value of the raw data horizontal and vertical in the given list. The parameter value is a IList for compatibility with other methods of graphical query such as FindNearestValue , return IList values containing raw data.

  A concrete example, say you had a graphical configuration with a wide horizontal axis ranging from 0 to 100 and a vertical axis double precision ranging from 10 to 20:

  
          
              
              
          
      

  To get the screen coordinates of the value at the center of the two axes, you can call:

  graph.DataToScreen(plot, new object[] { 50, 15.0 })

  Note that the raw data values corresponding to the type of axes (horizontal AxisInt32 returns the integer 50 and vertical AxisDouble Gets the value 15.0 ).

  You also mentioned a performance issue where "adding other plots does not affect the CPU so that they have a complete set of points". I did a simple test app that adds an array of two points of a chart on each key (for example graph.Data.Add(new[] { new Point(x1, y1), new Point(x2, y2) }); ), but could not reproduce the problem you saw. Could you share the code, you use to draw the connection line?

• draw the line between black pixel: coordinates of the selected pixels?

  Hello

  I want to build a script that can check a Photoshop file and:

  -find the black pixel

  -for each black pixel, looking for an another black pixel at a maximum distance of 5 pixels

  -then draw a line between the two black pixels.

  I wrote this script below (my first script...), but it's VERY slow (and my final image is VERY large), I think because I test the color for each pixel in the image.

  So an alternative would be to select a black pixel with the wand, then the script record all the details of the selected pixels, then my script wil test only the pixels (less than 1% of the pixels are black in my image).

  Is this possible with JavaScript?

  Thank you for your answer!

• I want to draw a line between 2 specific points on an image inserted in a Panel? Help, please!

  I am a beginner in working with LabWindows/CVI and I want to draw a line between 2 specific points on an image inserted in a Panel? Please help or examples of code.

  As evidenced by the Wolfgang there is a problem in the definition of recall. InstallCtrlCallback wants a reminder of the standard of review as a parameter: apparently you have structured your reminder callbackName on the prototype of a recall of Panel, which obviously missing the setting "control".

  In addition, the recall of control should be said somewhere before it can be used. In other words, you must add his statement before your function {main}, either in one of your include files, or directly in the code. This is the reason for the error 'found int, whereas CtrlCallbackPtr. '

  Third point: you create a new picture control in the callback assigned to the image control. And you reuse variable 'Test', which already holds a valid control ID...

  Finally: what you expect to make from '1' in callbackData parameter, given that you do not use anyway? Unless you want to adapt the behavior of recall some past in callbackData conditions, you must pass NULL as the parameter.

• Thick border line between two columns

  Hello all;
  
  I have a requirement where the user must be able to distinguish between two columns hnce asking a thick line, rather than the usual 'by default'.
  
  Everything is 'Default' until then.
  I clicked on properties of the 1st column and in the section "Border", I chose "Custom" and made the right wall of the cell in black color.
  I see a thick border now, but it has eliminated the 'default' border separating lines. His party make the entire column look like a single cell.
  
  I don't want any change with the exception only of the border of a column of a black line.
  
  Any help is greately appreciated.
  
  Thank you!

  The column properties-> Options of Style CSS custom (HTML only)-> use custom CSS Style->
  the following CSS code
  border-right-width: 1px; border-right-color: green;

  or go with someone with the necessary changes

  Appreciate if you score as correct if it works

• Straight line between two polar points

  Hi all

  I created a VI that could be traced a Polar curve according to time-distance formula. The VI has present Mag and target Mag. each with its own angle (Polar form that is (r, theta)). I want to draw a straight line from the current point to the target point. I used the time-distance formula to trace the scale and used the same slope to point the angle. However, I get a curved path as shown in the attachment.

  Could someone tell me what formula can be used to draw a straight line from the current point to the target point?

  Thank you.

  1 convert two polar points in rectangular coordinates.

  2. generate the points between the two.  You can use the function of ramp or some other methods to generate points.

  3 convert points to polar coordinates and draw.  Nice straight line!

  Of course, the question is why do you want a straight line when you use the polar coordinates?  He will not directly be r or theta.

• How to create sharp lines between two text boxes?

  I create a book that is written by several people, and so I want to create a "chapter... author.

  Like this:

  Chapter 1... Jon Doe

  chapter2 ................................. Simon Harper

  so that these points have always the same distance.

  Help, please!

  Well, if your 'chapter' and your 'jon doe' is in the separate text boxes, then there is no easy way to do it. (You could draw a bunch of lines dotted, which isn't difficult, but the only way to standardize manually drag the lines around).

  However, if "chapter" and "jon doe" is in the same text box, separated by a tab character, then it is quite easy. Have you used a ruler before tab? This gives a test:

  (1) type a brief sample in a text area, like the one in your post, but instead of separate columns with points, simply use a single tab

  (2) select all text

  3) go to the Type-> tabs

  (4) I hope it sounds familiar to you (probably from MS Word, or maybe using a typewriter) but otherwise,.

  (4A), click once on the sovereign to insert a tab stop

  4 (b) type a question in the area of 'leader', and

  4 c) press Tab or Enter to confirm

  FYI, it's what you want, a 'leader' or a 'leader of dot. Knowing that he has called a "Chief" will help you find it in InDesign help.

• line between two parts of a graph

  Hello

  I have a problem with my XY graph. Here it is:

  -My acquisition is completed on several frequency bands, each band is merged to the curve. It works perfectly as here:

  

  Here, I made the acquisition on 4 strips: 50 k - 100 k. 100 k - 150 k, 150 k-1, 15M and 1, 15M - 11M.

  But here's the acquisition even without the 150 k-1, 15 M

  

  You can see the lines in this band. How can I avoid them? (they are also there when I leave a band high frequency to a band of low frequencies, and it's horrible).

  Thanks in advance

  One pair of NaN will break the line on a XY Chart.  You can also trace the parts separately.  Only their colors/line types the same kind that they seem to be the same plot.  This tip is often used when the color highlighting of the sections of a graph.

  Hi Sarah!

  You can't create a separator menu item in the top menu.
  Create a submenu and put all your toolbar menu item.
  Between the items that you want to have a line, create a sepatator menu item

• funny things happening when you draw a line

  We're talking Ai CS5.

  I have a work plan with a mixture between 2 wavy paths, the kind of thing that you hope that the customer will not ask new :-)

  A path is in line with a horizontal guide at the top on the artboard and down by another.

  I draw a line between the two guides and nowhere segment near the mixture and expect to get just a boring straight line. Instead I'm out a lengthened version of the plantings, starting at the top with the first path and passing all stages of mixing arriving downstairs with the second path.

  Sorry, I have to describe it that way, but when I tried again once it no longer works, so I can't show you the result. Can someone explain what's happened here?

  TIA

  Steven

  Looks like you were in the Mode of insulation of the Blend object - you could accidentally entered this mode without realizing it by double-clicking on the object of the mixture. Now when you draw a simple line, the mixture is getting redesigned because now he sees 3 trails blend instead of the 2 paths.

  I hope this helps.

• Line between paragraphs

  I know that it is possible to make the text wrap around an image, as described in the link below. But is it possible to place an image in a line between two paragraphs without split text in two text boxes?

  Make the text around a picture

  You can put two text boxes and the image within a parent zone to achieve a similar effect, but you can not place the image inside directly inside a text box.

  Hope that helps and thanks for using the Reflow!

  Sanjay, it's a problem of client - customer is responsible for rendering data. If whites are needed, then the customer must make as a result.
