QUESTION
Is there anyway to get the underlying div element on a @ViewChild
? I have tried to read the following of which none work:
ElementRef.prototype.nativeElement
-- returnsElementRef
HTMLDivElement
-- returnsundefined
ElementRef
-- returnsElementRef
I am trying to do this so I can do without having to call nativeElement
in every call to the content
property.
Here is what I am doing (replacing the read
with an item from the list above):

QUESTION
I want to create a slide effect: one bitmap is painted from right to left on a form's canvas. For this I use BitBlt.
I call this function in a Timer (20ms):
...ANSWER
Answered 2021-Jun-13 at 19:12You should not be drawing on the Form's Canvas
from outside of its OnPaint
event at all. All of the drawing should be in the OnPaint
event only. Have your timer save the desired information into variables that the Form can access, and then Invalidate()
the Form, and let its OnPaint
event draw the image using the latest saved information.
Alternatively, simply display your BMP
inside a TImage
control, and then have the timer set that control's Left
/Top
/Width
/Height
properties as needed. Let the TImage
handle the drawing of the image for you.

I'm recursively creating a form but I'm getting a cannot find control with name error. You can see how I use in it in the stackblitz but the from is uncommented for me. In my opinion it seems like the form isn't being loaded for some reason because if I delete the insides of the form I get the same exact errors.

QUESTION
I'd like to have a 2 column reveal.js slide where I can page through the slides in the left-hand column (ColA) while a video plays in the right-hand column (ColB). The slides accompany the video.
I have it laid out on this page but the contents in the iframe/ColA are not large enough to read. I've tried scaling it but it scales the entire containing div, making the two columns overlap, and does not just scale the contents of the iframe.
Another option is to do the slides like normal, where each slide contains a link to the embedded video. My worry there is that every one of the embedded videos will play at once once the page loads because it's a live stream - it seems like that might eat a lot of processing power as my computer tries to play the same embedded live stream in 30 different slides. When moving from Slide1 to Slide2, are embedded videos stopped?
The full git repo for this is here.
...ANSWER
Answered 2021-Jun-14 at 10:32I don't think the iframe will work very well for multiple reasons:
- The scaling problem that you already encountered. iframes are notoriously hard to scale, as the size has to be hardcoded when embedding them.
- The nested presentation will have its own navigation, so it wont be clear where to proceed with the presentation.
You also already anticipated teh next problem - when putting the same video on multiple slides indeed the video will "restart" - first the old video will fade out and then the new copy will fade in. This is because each slide is it's own self-contained HTML element. So this also won't do what you want.
Instead I would propose to use Fragments. Fragments are the way you can have individual elements on a page change without changing the whole slide (commonly used for making bullet points appear).
In your case you can implement your "sub slides" on the left side as individual fragments that appear on top of each other using the css classes fragment fade-in-then-out
(to make them appear/disappear) and r-stack
(to make them appear on top of each other). You can see an example on the "Layout" page in the documentation (the second one with cat pictures).
If you put all of your sub-slides as fragments, then you can just have your video embedded as normal on the right and it will play independently from the subslides changing. Once the last sub-slide is passed, the presentation will move on to the next real slide (stopping the video).

QUESTION
I am trying to reveal some truncated text on hover. The text will all be dynamic so each li will be different lengths of text.
The ideal situation would be to hover the truncated text, it slides to reveal the full length of the text and ends at the end.
I have created something that is close to what I need, except I cant figure out how to remove all the extra space at the end of the shorter text on the right when hovered, and how to get it to show all the text on the longer ones (they seem to get cut off)
Here is the HTML:

QUESTION
I'm trying to make a landing page comparison slider that reacts on the mouseX position, but I want the slider to move the opposite direction of the mouse position. Any suggestions on how I can make that happen?
Demo: https://jsfiddle.net/uw5v94qf/
So basically, like the demo shows, in my case the slider follows the mouse position. But I want it to kind of do the opposite(?), that is revealing the current slide that the mouse is hovering. The more the mouse moves towards the edge, the more it shows that particular slide.
