D3 forcelayout label overlap with link - d3.js

I would like to display tooltip when hover a link
But sometimes the text of label of node got in the way--> no longer the mouse focus in hovering link.
Is there any way to completely ignore the label and let the link hovering happens as expected? Just like the label is not there (still display) anymore

How do you update all the TreeView items full area when the vertical scrollbar shows up or goes away?

I am using NM_CUSTOMDRAW to draw tree view items. My items right justify parts of it by using a right margin based on the RECT area reported available. The issue I have is that when the vertical scrollbar appears or disappears, only the item expanded/collapsed and the area under the scrollbar seems to update (invalidated regions). This causes the repaint requests (with the new width) to not update the area correctly.
For example (using text and a single space as example): You could have something with the scrollbar be right justified text ## where ## is the scrollbar then when the scrollbar goes away you end up with right justified text t instead of right justified text
Is there a good way to fix this?
One thought is if I could catch a message when a scrollbar shows up or goes away, I could just invalidate the window to force a redraw. Is there such a message?
Or is there a way to add to the invalidated region without triggering a redraw loop but would update the full items area?
Another thought is I can just use the full window RECT size and use a right margin large enough that wouldn't be under the scroll area but I'd rather not do that.
Thanks!

HOw to get rid of vertical "overflow:hidden" in Slick Slider

All. I am emboding the Online Store PSD design to HTML/CSS. Here is link.
There is an items slider in items page. Every item has configuration icons in the bottom of the it. When you hover on the item, second row of icons appear. Every configuration icon has its tooltip on hover. Let me describe the problem. Now because of Slick slider 'overflow:hidden' property on 'slick-list' block, the second row of icon is not visible fully. BEsides, tooltips are also being trimmed. If If I delete 'overflow:hidden', this problems disappear. But another problem appears. That is, now all slides are visible horizontally which are out of bound. If you visit the site, you notice in the bottom of the page 2 sliders. The second one has no 'overflow:hidden'. Therefore, everything is visible. But it is not good. If users monitor has high density, it looks very ugly. The first slider is by default. It has 'overflow-hidden' property , therefore everything out of bound is trimmed. I need only get rid of vertical 'overflow:hidden'. Is this possible? Thanks much, in advance.

position of a tab control tooltip

I created a tab control with TCS_TOOLTIPS style, hence when mouse is over tab items, it displays a tooltip which shows some information.
The tooltip always has the same x-position as the cursor and below the cursor.
I want to make the y-position of the tooltip exact at the bottom of the tab control. In this case, I need to increase the x-position of the tooltip also, in order to avoid the cursor and the tooltip overlap.
But I can not find any information to adjust the position of a tooltip of a tab control.
Is this related to TTM_TRACKPOSITION flag of TOOLINFO? When I created this tab control, I knows only : get hwnd of tooltip by sending TCM_GETTOOLTIPS message ; Treat WM_NOTIFY message and fill TTN_GETDISPINFO structure to display the tooltip. But I didn't find any information about the position.
Sub-class the tooltip control and modify it's position by catching the WM_WINDOWPOSCHANGING message.

How can I set a tooltip to display while dragging an NSSlider?

I've got an NSSlider. I've set it to update continuously. In my update code I have:
[quality setToolTip:qualityTooltips[pos]];
This updates the tooltip, but the tooltip is not displayed while I'm dragging the slider. In fact it vanishes as soon as you click the slider. I'd like it to always be visible while I'm dragging the slider, is this possible?
