graphical WPF detect the mouse on the axis

How can the interaction of the mouse with the axes of the events? With graphics WF, I used following code:

switch (graph. HitTest (provable, e.Y))
{
case XYGraphHitTestInfo.XAxis:

etc...

You can use the GetScaleAt method to detect a ladder to a given mouse position ( GetChildrenAtPoint should return scales as well, but this does not work in the current version).

Here is an example of using GetScaleAt in the MouseLeftButtonDown event on a graph (note that the graph should have a background of testable success as Transparent , instead of the value default null , or only clicks exactly on the visuals in the balance works):

private void OnGraphMouseLeftButtonDown( object sender, MouseButtonEventArgs e ) {

        Point screenPosition = e.GetPosition( graph );

        var scale = graph.GetScaleAt( screenPosition );

        Console.WriteLine( "Scale at {0}? {1}", screenPosition, scale == null ? "no" : "yes" );

    }

  • Graphical WPF reset the Axes of origin

    Hello

    Is there a way to reset a horizontal axis (0) originally?

    I already used ResetZoomPan(), but this only the definition panoramic and zoom to its original state.

    I would like to reset the chart as it appears from the first load.

    Thanks for all the help.

    Assuming that your chart is configured as in the example below:


          
            
          
          ...
        

    You can set the range using the element named axis:

    xAxis.Range = new Range(0.0, 10.0)

    Or by casting the first element of the Axes collection, if it is without name:

    ((Axis)graph.Axes[0]).Range = new Range(0.0, 10.0)

  • My macbook does not detect the dell wireless mouse

    I have the macbook air. I tried to connect my macbook to my Dell Wireless mouse. But my macbook could not detect the mouse

    Without a model number, we cannot exclude that particular mouse is incompatible with OSX, especially if it is old.

    OS X pair with a large number of devices bluetooth automatically, but some need to be put in pairing mode.  You will find the Dell mouse model and see if that is his business.

  • Is there a way to detect the mouse during the event for the controls within a tab control?

    I need to change the mouse pointer when it moves on controls that are found in the tabs.

    Now when the mouse passes over the tab, LABVIEW does not detect the saperately of controls for the mouse over event.

    Is there a way to do what I intend to do?

    Your problem is with the Panel.Controls [] property. It does not return the controls that are inside containers (tables, tabs, groups) and returns only the container itself. As illustrated by Sam, if you want the references to the controls in the tab, you must get the references to the pages and get the controls on each page and add them to your original table and do this recursively.

    You can either write a VI to do this (or search for it. There was posted here screw that analyzes recursively the FP for all control references) or everything just statically for this control a tab and move. There is also a VI delivered with LV that can help you with this, but I suggest that you not use, because it will be difficult to operate if you generate an EXE file.

    And I also recommend the Tool of Capture of Code.

  • IntelliPoint 8.2 will not detect the 4000 Wireless Mobile mouse

    I'm running Windows 7 pro 64 bit on a mobile workstation Dell M4800.  I bought a mouse Wireless Mobile 4000 which is supposed to have programmable buttons.  I went to the web page of material/downloads and downloaded Intellipoint 8.2 who is supposed to be the software for this device.  The software installed with no problem, but it will not detect the mouse and I can't program the buttons.  On the devices tab, the program detects the touch pad mouse and Dell (listed as compatible mouse HID).  The mouse works with the basic functionality, but I need to program the buttons

    Hi John,.

    If you have installed the correct versions for the mouse, then, it could be a problem with the mouse settings associated with the soft keys.

    For confirmation, this is the link for the latest driver:

  • How to detect the direction of the mouse and change of scenery?

    Hello

    I'm building a single 360 degree rotation effect using individual images and buttons front and back . I am new to AS3 and have managed to create functioning buttons... (so my code can be a little weird!)

    But now, I would also like to advance frames by clicking and dragging on the image itself (or on an invisible button sitting on top of the image).

    Although there are some threads here that have asked the same thing, I don't understand how they were answered. My code is below, and the file with that I'm practicing is located on:

    https://download.yousendit.com/MVNjeFlWSWh6NE4zZUE9PQ

    Currently if you click on the area of the image, it will move forward, but there is no code to detect the direction of the mouse, he'll just before. Can someone help me understand how to set up a simple direction detection and then use it to decide whether to move forward or backward... Thank you!!

    Stop();

    move forward 1 frame on click

    function forward(e:MouseEvent):void {}

    If (currentFrame == 15) {}

    gotoAndStop (1);

    { } else {}

    gotoAndStop (currentFrame + 1);

    }

    }

    go back 1 frame during the click on

    function back(e:MouseEvent):void {}

    If (currentFrame == 1) {}

    gotoAndStop (15);

    { } else {}

    Stop (currentFrame - 1);

    }

    }

    btn_fwd.addEventListener (MouseEvent.CLICK, forward);

    btn_bck.addEventListener (MouseEvent.CLICK, return);

    change frame on direction of mouse?

    function MouseMove(event:MouseEvent):void {}

    {

    if(event.buttonDown==true)

    If (currentFrame == 15) { }

    gotoAndStop (1);

    }else{

    gotoAndStop(currentFrame + 1);

    }

    }

    }


    stage_btn.addEventListener (MouseEvent.MOUSE_MOVE, MouseMove);

    With the help of Content="{Binding LabelX}" in the LabelTemplate won't work if Label is defined on an object with a property called LabelX . I think that what you want is something like this:

    Label="{Binding LabelX}">

            

                

                    Content="{Binding}" />

  • Alienware M15x does not detect the graphics card, GeForce GT 555 M

    Hey guys, I ask you bear with me for the whole story because I believe that it may be relevant.

    I just bought this laptop (M15x) pre owned, it came with windows installed 8.1 and a load of games and others with all the drivers work and tact. Although it has been slow and some errors like may be able to control the volume.

    CPUID other programs showed my 1024 MB graphics card but I don't remember the name but I'll what nvidia says on their site and the description says...

    I didn't like windows 8 and I thought, rather than make clean for a week I'll install windows 7 from scratch, I did. Windows 7 ultimate 64-bit for info

    After doing this, I started to install anti virus and others and then to install the drivers, many of which I don't know, but analysis system dell raised all of the recommendations I installed, everything outside the video... none seems to fit my current card. I left it... went to nvidia which part of the site told me that he could not find compatible hardware... another part of the site classified as GT 555 M, but I had to go to my manufacturer to get the driver.

    After a few discussions with local technicians and these and other forums, I tried the drivers provided dell card among other NVIDIA covering my amog others but none worked and could not find compatible hardware...

    I thought it was that I installed the drivers in the wrong order, after an accident, I installed windows 7 over again and went straight on the chipset driver, then the video driver. but I fell on the same subject.

    After looking over several forums, the only thing I can come up with is to turn off graphics integrated into the bios (option not available for this)

    Maybe windows 7 doesn't like this graphics card? I am at a loss. given that everything worked fine on windows 8.1

    also in the device manager it does not list my card on the pc there is nothing wouldn't prove that I have a graphics card to all even the windows own evaluation system set to 1 for graphics NOTE from the ADMIN: replace character removed according to the TOU >

    Please help me...

    The GT 555 M has been never delivered with the M15X, but with M14X R1, so the former owner must have updated the GT 240 M graphics card. This explains why the drivers from the website corresponds to your configuration.

    Try this version of the driver from the NVIDIA website and let me know how it goes.

  • Is it possible to set the axis prior to 'spin' on a form or a sub-channel

    After clicking on a shape or subcircuit in mode 2D structure of EM, there are "rotation" and "flip" command in the context menu. Is there a way to enter precisely into the axis to the plane of rotation and symmetry to overthrow?

    I misread the original question, sorry.

    After launching the rotate or flip command, the first place you click with the mouse will define the origin of the flip or rotate it.   You can hold down the Ctrl key to align with the peaks forms or you can type Tab to use the space bar to get in the coordinate entry model to enter an exact coordinate as the origin of the flip or rotate.

  • ScatterGraph does not manually change the axis to execution interval

    I use the ScatterGraph and the WaveFormGraph in VS2010 Winforms application.  I have the interaction mode axes set to EditRange.  The WaveFormGraph command allows to edit the axis range by clicking on the end of the axis labels and modify them.  ScatterGraph control is not even though the documentation I've read says it should.  The mode of the axis does not seem be the question that I have changed between fixed and AutoScaleLoose (which is not the choice to have everything showing changing data, if you want your range entered manually to maintain).  I tried a new project with a ScatterGraph control with the default settings and checked that it does not change the axis interval.  Is there a way to change the settings to allow you to manually edit a ScatterGraph range in this way when running?

    Thank you!

    Hi Lybro,

    You have activated the "EditRange" of the graphical object of point clouds InteractionMode? There are two places that the mode of interaction is defined, one for the axis and the other for the scatter chart, both must be enabled for writing at work. I just tested this with Measurement Studio 2013 and it works. Let me know if it helps.

    Kind regards

  • Add the label of the axis to a chart in the report of the word

    Hello

    Is there a way to add a label to the axis of the graph in a word of the report? Thank you!

    Tom

    It is of course not very intuitive to use the word graphic Set make vi to set the label of the scale.

    Use xlCategory and title of entry to affect the scale label x and use xlValue and title of entry to set the label of scale there.

    It would have been nice and easy to add an entry to set the orientation of the text (just adding an argument in the node of the axis title property).
