I have an issue with svg groups and basic animation. this guy is a button. When hovered over, out pops a sort of menu. The goal is that the menu retracts when the mouse pointer leaves the button and the menu.
The trouble starts with 'onmouseout'; even though button & menu are grouped, and with 'onmouseout' acting on the whole group, the mouseout action is triggered by mousing out ANY element within the group. So a move from button to menu triggers the retraction.
To work around this I've put a mask over the top that appears (so to speak - it does become visible but has 0 opacity, so cannot be seen), when the button is moused over. I've turned it grey here so you can see it. But if i want to add element onto this menu, I'm no further forward than before. The red block is this other element.
Seemingly, if I had the menu just appear instead of using animations to make them appear, the groups would behave as I want them to.
I hope someone can help or shed some light.

Is there a way, after selection of a color, to programmatically hide the color picker of the TComboColorBox? I've searched on the web and Embarcadero community but couldn't find a way to do this.
The answer is no, there is no designed way to hide (collapse) the popup programmatically. And you did not explain why you think it would be necessary to have.
Keep in mind that there are 4 subcontrols, that the user may want to use:
a THueTrackBar,
an alpha channel trackbar,
a color quad, and
a hex color value edit box.
An automatic collapse of the popup would be just annoying.
The user can at any time decide to close the popup simply by clicking on the constantly visible bar.
With reference to your comment:
After your answer, I realized that I must implement a color picker component that shows a rect containing a TComboColorBox and a TButton as childs. Clicking the child button, in turn, hides the container rect itself.
I have told you twice that the user can close the popup part of the TComboColorBox simply by clicking on the component (the base part of it).
In fact, the user can click anywhere outside of the popup window in order to close the popup window. The popup is closed immediately when the focus moves away from it.
In my opinion there's no need for a special "Close" button.
So I downloaded CircleView and tried to change the code. The program came with a button, color wheel, 2 sliders, and a view. When ever I add anything (Slider, button, textfield), on run time the things I added wouldn't show up. What am I not doing?
It's a .nib file.
This is the edit page.
This is what I see when running the program.
As you can see, the button and textfield doesn't appear during run time.
By default, when you add a button, the autoresizing mask (aka "springs and struts") are set to the following:
That means that when you resize the window, the button you added will stay in the same spot it originally was, instead of being "pulled" down with the edge of the window. This could potentially cause the buttons or textfields you added to be hidden behind the circle view once you resize the window large enough.
To prevent that from happening you'll want to change the autoresizing mask of the items to be "pinned" to the bottom edge of the window, so that they look like in the following image:
To do that, click on the red I bar at the top of the square to remove it, and then click on the lower I area to turn it on.
Note that you can also select multiple buttons or textfields at one time to change them all at the same time.
I've been struggling for weeks trying to crack this nut so I'm not sure if it's impossible, or if it's my lack of coding chops... or both. I'm not a programmer and I'm a newbie to Dojo Toolkit.
I have a site using the BorderContainer layout. I'm trying to create an effect where I can use a button to open and close a dropdown type box that will contain controls. I need this dropdown to be hidden on page load, and then open when you click the button.
My problem is that when I open the dropdown, it pushes the content pane below it off the bottom of the browser window. I need the lower ContentPane to stay fit within the remaining space of the browser window when the dropdown opens. Additionally, I want the dropdown to sit outside of the scrollable container for the content below it, which is why I have it set up to sit outside a nested BorderContainer below it.
I've created a simplified version of the code to demonstrate my challenge (see link below). If you load the page you can see the center ContentPane scrolls the content. But, if you then click on the button, a dropdown div expands above the content. Then when you scroll, you'll notice that you can't see the full pane because it's in no-man's-land below the bottom of the browser window. I assume that because the div is set to display:none on load, it's size is not accounted for on page load. Then, when you open it by pressing the button, it's size is additive and the pane below doesn't know how to resize or account for the new element.
I've tried using the visibility attribute, but that leaves a gap for the div when it's still closed. I've tinkered with some code that controls the height that shows promise, but each of my dropdown boxes will be different sizes so I'd prefer that the height be set to "auto" rather than a specified pixel size.
Does anyone have any idea how I can accomplish this so that the lower pane will fit in the space without pushing off the screen?
Here's a sample of the page:
http://equium.com/scaffold.html
(I had some problems trying to insert the full HTML page here as a code sample so if that's a preferable way to handle it, and someone can let me know the best way to embed all of that code, I'd appreciate it.)
Thanks is advance, I'd really apprecaite anyone's feedback.
You might want to take a look at dojox.layout.ExpandoPane (though be warned I think it has only worked properly for top and left regions for a while).
Also, I'd suggest simplifying/altering your layout a bit. See example here:
http://jsfiddle.net/taFzv/
(It'd probably need some tweaking to get exactly what you want.)
The real issue you're having is probably that the BorderContainer has no idea that parts of the view resized. ExpandoPane takes care of that by telling the BorderContainer to re-layout after its animation completes.
It works under IE8.0. When dropdown box open, just keep pressing mouse from page and drag to bottom, you could see the content was pushed to out of page. It looks the browser could not detect it and could not add it to "scroll bar" account.
I would suggest taking out all BorderContainers except your top level one, the one with mainPage as the id.
Place your {stuff here} div into the mainPage BorderContainer, after the ContentPane with the Close/Open button. Make sure you make it dojotype dijit.layout.ContentPane, set up layoutpriority, and set region to top. Set the height to 0/x when clicking the Open/Close button, instead of setting display.
Try your page again. If that doesn't fix it, you probably need, a call to layout, resize, or both to indicate to the BorderContainer that it needs to evaluate all its children and size the "center" pane properly. Something like dijit.byId("mainPage").layout(); Do this any time someone presses the Close/Open button, after you have changed the height of any BorderContainer children.
Maybe the dijit.form.DropDownButton would fit your needs. When click the button a tooltip is displayed that can be filled with any content you want. Just as you specified, the dropdown tooltip is only displayed when you click the button, and it doesn't mess with the underlying layout at all. The tooltip sits "on top" of the page.
If you tap on the left hand side of the screen in Outlook then an event is triggered (in this case a checkbox appears).
I would like to know the xaml on how this is achieved. It cannot be a simple "MouseLeftButtonUp" event because if you drag your finger more than a few pixels then the event does not trigger.
In my own app I am trying to get an icon appear within a listbox that has a SelectionChanged event. The issue is that if you do not touch the small icon precisely then you are triggering the listbox event rather than the event I want to occur when pressing the image.
I think I need to wrap my image in a Canvas but then am still stuck as to what the event should be.
How do you increase the target size of the area where a user can click on your element?
What event should an image have when within a listbox (which is within a pivot) that has a SelectionChanged event? (MouseLeftButtonUp causes issues if you half drag to the next pivot and lift your finger - it triggers the MouseLeftButtonUp event)
I implemented something very similar to that behavior by making an itemtemplate where the checkbox was pushed offscreen to the left by using a negative margin.
I then created 2 visual states, one for Open and Closed. The open state set the margin to 0, bringing the checkbox back onscreen. Closed state had the negative margin.
With the fluidmove behavior, switching between states on button press was EASY. The only thing you'd have to add would be an invisible button/touch area on the left that would also trigger "opening" the checkbox column (changing state to reset the margins).
Hope that helps...
The outlook app is a native app, so it probably isn't using xaml at all.
If you're worried about the mouse events, then you should look at the gesture stuff in the silverlight toolkit, it contains tap, etc events that make a little more sense on the phone.
Increasing the target size and generally making stuff touchable: wrap it in a Button, then alter the ControlTemplate for the Button to remove the border.
If you look at the ControlTemplate for a Button, (Expression Blend, Edit Template, Edit a copy) you'll see the mechanics of the touch area. It's nothing more than padding/margin.
Thus, you can't bleed your touch region out without altering the layout and affecting other items around the control. I'd do two things:
First, I'd think about whether my whole control should be larger in the first place with good spacing around it. Is my design right?
Second, I'd cheat. I'd float a fixed sized button with no border over the area using the Translate transformation to move it around freely.
Good luck,
Luke
What I am trying to accomplish with Cocos2d, is to create a horizontal menu, which can be swiped from left to right. I posted an image, to show my idea.
The image below has a white bar, where I want to show MenuItem objects, now I want to be able to do a swipe in the white region, so that the next menu item is centered.
Example http://www.wimhaanstra.com/images/MenuExample.png
The problem I am facing is, I would really like to use the Menu (& MenuItem) functionality of Cocos2d, but it seems somehow that the MenuItem object does not accept touches other than just tapping it. Also I want the swipe to be detected not only on the MenuItem, but the whole white bar.
What would be the best approach for this?
Somehow incorporate an UIScrollView, but that would be a shame, because I would like to use OpenGL for everything
Subclasss the MenuItem class, to create one where the ccTouchBegan is handled, and somehow move the whole Menu?
Just leave the whole Menu idea behind, and replace the Menu and MenuItems with sprites which support touching.
I read somewhere that MenuItem's shouldn't really be used for this kind of work, but why not?
Layer can handle touches event.
you can put you menuItems into one layer.
detect a swipe, and move the the menuItems
