• How to tell if XUL menupopup opens down or up?

  - by Jon

  I have an extension that can be placed on any toolbar (like the bookmarks, menu or status bars). In general, the context menu opens downward, but when placed on the status bar and Firefox is closed to the bottom of the screen, the context menu opens upward. I'd like to try reordering the context menu based on its up or down orientation, so that the same options are always closest to the mouse. For example, when opened downward it appears like this: -- (mouse) --------------- - MenuItem A - --------------- - MenuItem B - --------------- - MenuItem C - --------------- - ....... - --------------- When it opens upwards its like this: --------------- - MenuItem A - --------------- - MenuItem B - --------------- - MenuItem C - --------------- - ....... - --------------- -- (mouse) However, I'd like "MenuItem A" to appear closest to the mouse at all times, since its the most common item. I can render the items dynamically, so I really just need to find out the orientation.

• Dynamic size canvas with Scroll bars

  - by Pawan

  Hi, I am developing a simple WPF application without any auto layout. The goal is when a user clicks (mouse down) a element (say textBlock) will appear at the location of the mouse click. For this I am using canvas panel embedded in a Grid of 1 row, 1 column and scrollviewer (visible). The issues are: 1. when the application window is resized the scroll viewers do not become active. 2. I want the ability to auto grow the canvas with mouse drag. Something like in MS-Excel when user drags the mouse horizontally/vertically the canvas should grow. I have searched net a lot to figure this out and am unable to get an answer. Any help in this regard would be great. Thanks a bunch in advance. -P

• Cursor image to the center on mouseout

  - by Milla

  Hi all! I'm a real noobie with flash and I was wondering if somebody could help me with this one. I have this actionsript 3 code, where the cursor image "ball_mc" follows the mouse's position with a slight delay: stage.addEventListener(Event.ENTER_FRAME,followBall); function followBall(event:Event):void { var dx:int = ball_mc.x - mouseX; var dy:int = ball_mc.y - mouseY; ball_mc.x -= dx / 5; ball_mc.y -= dy /5; } 1) How can I get the cursor image automatically return to the center of the stage on mouseout? As of now, it stays at the position where the mouse leaves the stage. 2) How can I reverse the movement of the mouse? So that when I, for example, move mouse to the right, the cursor image would move to the left? And when moving the mouse up, the image would go down. The stage is 800 x 250 pixels, in case that makes any difference.

• Why function Ellipse(...) are needed twice here to draw an ellipse?

  - by John Son

  MFC: I read this code which is to draw an ellipse (not solid interior), but I cannot understand why function "pDC-Ellipse(...)" is needed twice here? CDC *pDC=GetDC(); CPen pen; CBrush brush; getpen(pen,pDC,col,bol); if(do_what>=DRAW_LINE&&do_what<=DRAW_RRECT){ p->p[0]=start; p->p[1]=end; if(sol==1){ getbrush(brush,pDC,col); } if(do_what==DRAW_LINE){ pDC->MoveTo(start); pDC->LineTo(end); } else if(do_what==DRAW_ELLIPSE||do_what==DRAW_CIRCLE){ pDC->SetROP2(R2_NOT); assist=start; if(do_what==DRAW_CIRCLE){ assist.y=end.y-end.x+start.x; } pDC->Ellipse(start.x,assist.y,end.x,end.y); pDC->SetROP2(R2_COPYPEN); if(sol==0){ pDC->SelectStockObject(NULL_BRUSH); } if(do_what==DRAW_CIRCLE){ assist.y=point.y-point.x+start.x; } pDC->Ellipse(start.x,assist.y,point.x,point.y); end=point; } } If I remove the first one, the ellipse will be black solid inside. If I remove the second one, the ellipse will never be drawn but disappears when left mouse button is up. the dialog: when moving mouse: mouse moving when mouse button pops: mouse button pops Besides, what color of CBrush is if I use "CBrush brush; pDC-Ellipse(start.x,assist.y,end.x,end.y);"

Am I doing something wrong? Currently developing a flick and scroll control.

• Chrome: On pressing Enter on a Textbox of a <form> Submits page without calling onClick of submit bu

  - by X-eCuTeR

  Hi Folks, I have a scenario in which I have 2 Submit Buttons in a form for going back and forward. Both the buttons have different JavaScript associated with it. It is working great if we press these buttons to navigate. But when in Google Chrome, when someone press enter on any of the text box within the Form it does not calls the onClick of the button. Is there any work around for that. Thanks

• Nested ListBox in DataGrid? Inherit style?

  - by Chris

  I have a DataGrid with multiple columns. The data grid has a style that changes the forecolor of text on a row where the mouse is over or the row has been selected. So the text color will change from black to white, for example. In one of the columns in the data grid, I have a ListBox. Is it possible for the items in the list box to have the foreground change to that of the data grid row, when you do mouse over or select the data grid row? I don't want to have a style for the list box that is specific to mouse over for the list items, I just want the foreground of the list items to change automatically to the forground of the data grid row when the mouse is over the row or selected the row. So even if the user moves their mouse over a different column (that doesn't contain the listbox) - I would want the foreground for the listbox to change. How can I go about doing this? ValueConverter? Thanks. Chris

• cycle through four list elements, applying an "active" class.

  - by Derek Adair

  Hi, I would like to cycle through four li elements that all contain tags, setting the appropriate class to "active" and remove the "active" class. I'm having a bit of trouble figuring out how to achieve this via jQuery. HTML: <ul class="liveMenu"> <li id="leftScroll"></li> <li id="liveButton_1"><a class="buttons" href="#featured_1"></a></li> <li id="liveButton_2"><a class="buttons" href="#featured_2"></a></li> <li id="liveButton_3"><a class="buttons" href="#featured_3"></a></li> <li id="liveButton_4"><a class="buttons" href="#featured_4"></a></li> <li id="rightScroll"></li> </ul> jquery: var index = 0; $("#rightScroll").click(function(){ if(index != 3){ index++; } else { index = 0; } //this part is untested, it should work though $("a.active").removeClass("active"); //this is where I am getting hung up //I need something like... $.each("li.buttons", function(i){ if(i == index){ $(this).addClass("active"); } }); }); $("#leftScroll").click(function(){ if(index != 0){ index--; } else { index = 3; } $.each("li.items", function(i){ if(i == index){ $(this).addClass("active"); } }); }); any help would be greatly appreciated. Thankyou.

• UIView Obscuring Other Views

  - by Matt Long

  I cannot figure out what is obscuring my buttons. The first image shows the buttons that I want to click. They are clickable while the view is contracted like this, but when the view is expanded like in the second image, the buttons are no longer clickable. There seems to be another view obscuring the buttons. Any thoughts on what might be causing that? If not, any idea how I can figure out what view is getting the tap events when I tap in that area? Thanks. -Matt

• JavaScript + Maths: Image zoom with CSS3 Transforms, How to set Origin? (with example)

  - by Sunday Ironfoot

  My Math skills really suck! I'm trying to implement an image zoom effect, a bit like how the Zoom works with Google Maps, but with a grid of fix position images. I've uploaded an example of what I have so far here: http://www.dominicpettifer.co.uk/Files/MosaicZoom.html (uses CSS3 transforms so only works with Firefox, Opera, Chrome or Safari) Use your mouse wheel to zoom in/out. The HTML source is basically an outer div with an inner-div, and that inner-div contains 16 images arranged using absolute position. It's going to be a Photo Mosaic basically. I've got the zoom bit working using CSS3 transforms: $(this).find('div').css('-moz-transform', 'scale(' + scale + ')'); ...however, I'm relying on the mouse X/Y position on the outer div to zoom in on where the mouse cursor is, similar to how Google Maps functions. The problem is that if you zoom right in on an image, move the cursor to the bottom/left corner and zoom again, instead of zooming to the bottom/left corner of the image, it zooms to the bottom/left of the entire mosaic. This has the effect of appearing to jump about the mosaic as you zoom in closer while moving the mouse around, even slightly. That's basically the problem, I want the zoom to work exactly like Google Maps where it zooms exactly to where your mouse cursor position is, but I can't get my head around the Maths to calculate the transform-origin: X/Y values correctly. Please help, been stuck on this for 3 days now. Here is the full code listing for the mouse wheel event: var scale = 1; $("#mosaicContainer").mousewheel(function(e, delta) { if (delta > 0) { scale += 1; } else { scale -= 1; } scale = scale < 1 ? 1 : (scale > 40 ? 40 : scale); var x = e.pageX - $(this).offset().left; var y = e.pageY - $(this).offset().top; $(this).find('div').css('-moz-transform', 'scale(' + scale + ')') .css('-moz-transform-origin', x + 'px ' + y + 'px'); return false; });

• Setting Tab Order on UI Elements in jQuery Dialog

  - by McNamron

  Is there a way to specify the tab order of the elements within a jQuery Dialog which itself contains an Accordion? The dialog also specifies one button in the buttons options. For accessibility, we need to be able to tab through the accordion panes, the form elements in each accordion, the button in the buttons options, and the close icon of the dialog itself, but tabbing seems to be skipping over the button in the buttons options, and I can't find any resource that has a resolution for this sort of problem.

• iPhone SDK allow touches to affect multiple views

  - by Parad0x13

  I have a main view that has has two buttons on it that control methods to display the next image and display the previous image. In this case the 'Image' is a class that inherits from UIImageView and has multiple pictures on it that you can interact with, and I call this class a 'Pane'. The pane itself handles all the user interaction itself while the main view controls the display of next and previous panes with the buttons. Here is my dilemma, because the pane fully covers the main view it wont allow for the user to tap the buttons on the main view! So once a pane pops up you cannot change it via the buttons! Is there a way to allow touches through transparent parts of a view, or if not how in the world do I achieve this?! I cannot pass touchesBegan or any of those methods from the pane to the superview because all of the button touch methods are created in the xib file. I cannot insert the pane under the control panel because then you wouldn't be able to interact with the pane. And as far as I know theres no way to pass touch events to every single pane within the paneHoldingArray that belongs to the main view I cannot add the command buttons inside of the pane because I want to be able to replace the command button's image with a thumbprint render of the next/previous pane. I've been stuck on this for a very long time, please somebody help me out with a fix action or a new way to re-engineer the code so that it will work!

• Setting Mnemonics and Hot Keys for a JOptionPane Dialog

  - by Daniel Bingham

  Is it possible to assign hotkeys and mnemonics to the buttons in a JOptionPane Dialog? I'd like to be able, in a JOptionPane generated message dialog with the options Yes, No and Cancel, press Y to hit the Yes button, N to hit the No button and escape to activate the escape button. Similarly in a dialog with Okay and Cancel buttons I'd like to be able to activate them with enter and escape. I've attempted passing JButtons into the JOptionPane's button Object array with the Mnemonics set already. The mnemonics work and the buttons show up correctly in the dialogs, however, they do not act properly when they are activated. Most noticeably they do not dispose of the dialog. What is the correct way to add hotkeys and Mnemonics to a JOptionPane Dialog's buttons? As always, my apologies ahead of time if this is a duplicate - I searched both Google and Stackoverflow and found nothing.

• Is there a way to catch a MOUSE_UP Event over a static textfield in Flash?

  - by Jovica Aleksic

  When the user presses the mouse, and releases it over a static textfield with selectable text, no MOUSE_UP event is fired - not on the stage and also nowhere else. I experienced this when using a scrollbar class on a movieclip with a nested static textfield. When the user drags the scroll handle and releases the mouse over the textfield, the dragging/scrolling is stuck. To test this, create a new AS3 fla file, place a static textfield somewhere, and put in some text. Make sure the selectable property is checked in the properties panel. Add this script to the timeline: import flash.events.* function down(event:Event):void { trace('down'); } function up(event:Event):void { trace('up'); } stage.addEventListener(MouseEvent.MOUSE_DOWN, down) stage.addEventListener(MouseEvent.MOUSE_UP, up) Now test the movie and click the mouse. You will notice that trace('up') will not occur when you release the mouse over the textfield.

• Issue with button text shifting

  - by Fizz

  I'm having this odd issue. I have these buttons where the button's text is shifted downward upon certain actions. For example, I have a spinner with choices and one of the choices makes some buttons invisible while others are made visible. When I choose these, the buttons made visible all have their text shifted downward. Nothing else is shifted, just the text on the buttons. I've tried this on 1.5 and it works fine, no text is shifted, but I have issues with 2.1 and I really cannot figure it out. Any ideas or help would be great. Thanks.

• Interface Builder only allows one button to be "touchable"

  - by STLMikey

  I'm making a clone of the classic game simon, the memory matching game. My (iPad) app will load fine, i tap start, the game screen loads, and only one of my four buttons will respond to touch commands. To troubleshoot, I tried creating a second unrelated nib and just populating it with four buttons not linked to anything. However, only one of those four buttons would respond to touch! There are no IBActions being called, nothing. Both the view itself, and all four buttons are touch enabled in the inspector...I'm stumped. I'm moreso asking if anyone has encountered anything simillar, as I'd rather not burden potential help with app-specific questions if it's avoidable. Thank you!

• Possible to add javascript to Zend_Form_Element_Radio?

  - by Stepppo

  Ultimately, I'd like my Zend Form to render this HTML: <p>Do you have any documents to upload?</p> <p>Yes <input type="radio" value="Yes" name="uploadChoice" onClick="showTable()">&nbsp;&nbsp;No <input type="radio" value="No" name="uploadChoice" onClick="hideTable()" checked></p> Here's what I have in my Zend_Form: //create radio buttons $uploadQuestion = new Zend_Form_Element_Radio('upLoadQuestion'); $uploadQuestion->setLabel('Do you have any documents to upload?') ->addMultiOptions(array( 'yes' => 'Yes', 'no' => 'No' )) ->setSeparator(' '); The problem I'm running into is how to add the onClick="showTable()" and onClick="hideTable()" elements to their respective radio buttons. In the alternative, I could rework the javascript and add something like onClick="toggleTable()" to the radio buttons if I can't add something different to each of the radio buttons. But, will Zend let me do that?
