If statements?

[Super_Saxy]

Hey,

I've searched all over this site and the internet in general, and either there isn't an answer, or I looked over it accidentally.

Is it possible to have any "if statements" when editing SVG code? I want to set up an animation to trigger via an access key, but only if a certain condition is met (or, set it so that the animation won't trigger if the condition isn't met).

Is this possible? If it isn't, is there something similar I could do? I know that there is a <switch> command in SVG code, but I read somewhere that it isn't supported with Blackberry SVG files.

Any help would be greatly appreciated.

Thanks!

Basically, your asking if SVG code supports boolean expressions....? I have been wondering about this as well.

Anybody know?

[Super_Saxy]

exactly. It would make life a whole lot easier.

Really any type of conditional statements would do.

Can anyone give any insight on this?

This is technically possible using SVG, but the theme builder and device do not support it.

I should also add that I would kill for this functionality. That, and the ability to force the cursor to "focusin" on an object when another is clicked.

thats frustrating.

I'm trying to have a dock that "slides" in and out via a accessKey activated animation. The problem is that when I press the spacebar to slide the dock in, it will replay the animation every time, EVEN if the dock is already out. I would love to use a conditional statement to make it so that the dock will not slide out if it already is.

Anyone have a suggestion for this issue?

does anyone know if I can use the <set> command with position? For example,

<set xlink:href="xxxxxxx" attributeName="x" to="0" begin="0" />

to fix the dock issue... when you click to hid the dock.. also turn off the display...

<animateTransform blah blah "#Dock" blah.. dur="0.5s" begin="accesKey(SPACE)"
<set blah "#Dock" display="none" begin="accessKey(SPACE) +0.5s">

you delay the display=none by the amount of the duration for the hide... get it?
so after it slides down, it then disappears. Be sure to dispay it again when you click the slide up key.

no, you cant set a move... you need to do a transform="translate"

Hmm...that's the biggest issue with using hardware buttons to trigger animations. If you opted for software buttons, you could "hide" the ON switch and replace it with the OFF switch instead.

While not optimal, you could create a duplicate set of icons and dock and set it up so that this duplicate set of dock and icons just "hides" and "shows" in the fully up position. This way you won't have to animate the duplicate set since it's already in position. (#iconsdock2)

1) When the space bar is pressed, animate #iconsdock1 to slide up. At the same time (after a duration delay of some sort), have #iconsdock1 hide and "show" #iconsdock2. The user wouldn't even be able to tell. Since #iconsdock1 is now hidden, even if they press the space bar it will run the animation but it will not be visible to the user.
2) When the user presses an alternate hardware key to hide the dock, position #iconsdock1 to be in the same "up" position, "show" #iconsdock1, hide #iconsdock2, and animate the slide down with #iconsdock1.

Of course, setting up scroll paths with something like that requires some thought, but it's possible. My recommendation would be to only allow scroll paths to reach the icons in #iconsdock2, since it's the only visible icons the user will ever see.

After that, #iconsdock1 is visible but below the screen as it always should be, #iconsdock2 is hidden as it should be, and you should have no problem looping.

What about when the user wants the dock visible? I think he's saying that when they press the SPACE key to bring up the dock, once it's up if they press the SPACE key again it repeats the animation.

[Super_Saxy]

Here is what I came up with:

		<animateTransform xlink:href="#Top_Dock" id="_anim_l6" attributeName="transform" type="translate"
						to="0,80" dur="0.5s"  
						fill="remove"
						begin="accessKey( )"
						restart="whenNotActive"	/>	

		<set xlink:href="#Top_Dock" attributeName="display" to="none" begin="accessKey( ) +0.5s"	/>

		<set xlink:href="#Top_Dock_2" attributeName="display" to="inline" begin="accessKey( ) +0.5s"	/>

						
		<animateTransform xlink:href="#Top_Dock_2" id="_anim_d6" attributeName="transform" type="translate"
						to="0,-80" dur="0.5s"  
						fill="remove"
						begin="accessKey(ESCAPE)"
						restart="whenNotActive"	/>

		<set xlink:href="#Top_Dock" attributeName="display" to="inline" begin="accessKey(ESCAPE) +0.5s" />

		<set xlink:href="#Top_Dock_2" attributeName="display" to="none" begin="accessKey(ESCAPE) +0.5s" />

The code starts with "top dock" above the screen, and "top dock 2" in the proper location on screen. Both docks start out hidden. When I hit the spacebar, "top dock" flies in, and immediately after the annimation, "top dock" hides via display and "top dock 2" shows via display. On the escape key, "top dock 2" animates flying off teh screen, then immediately hides and "top dock" sets to display again.

This combination has completely solved the problem with hard key dock hide/show!!!

I had to add a few things to solve some minor annoyances. I had to add the "repeat" command to stop the animation from restarting if you pressed the accessKey while it was running. I also had to change the fill to "remove" to put each of the two docks back in their original place.

There is one minor issue though. "top dock" and "top dock 2" are set to device application order. They obviously display different things. So when the one flies in it shows certain icons, and when it hides and displays the other dock, it shows different icons. Is there a way around this? Is it possible to have both docks display the same icons, even with "device application order"?

[hastings]

Yup. When you add an icon using composer and set it to application order, pay careful attention to the code used to display the button.

Notice: "<useApplicationIcons app-id="slot8""

By changing the "slot8" to something like "slot9", you can specify which "slot" it takes in the application order. Set each icon in both docks to the same "slots", and you're good to go.

You're the man!!! Thanks so much.

Another 2 cents for sliding docks on non-touchscreen devices:

Let's say, for example, the dock is at the bottom of the screen and slides south when hidden. I create a hotspot south of the dock, off of the visible display, and set the focus order so that trackpad down from any of the dock buttons goes to the hotspot. The hotspot is set so that when it goes into focus, the dock hides and when it comes out of focus (trackpad up) the dock is shown.

You can also do some other nice things with this method, such as retaining which 'page' a scrolling and hiding dock is on by having a hidden hotspot for each page.
