JavaFX MenuBar items flicker when moving pointer on it - linux

I have inherited a JavaFX project and have a problem when running it on linux. When dropping down a MenuBar menu and hovering over items with my pointer the selection flicker and items get selected only at certain spots of the area of the item. Where these spots are and the distribution of select vs. non-select spots are seemingly random, changing when closing the menu and opening it again. When clicking an item when it isn't highlighted as hovered nothing happens.
What could be the problem and where would I even start looking. I can't find anything that has been customized when it comes to the dropdown menus and they work flawlessly on macosx.

Excel scrollbar doesn't allow screen to update until you "drop" the scrollbar

This is hopefully pretty straight forward, but after an hour of searching online, I couldn't find anyone else complaining about this issue. Perhaps I just haven't found the right wording to describe it.
My company recently switched to Excel 2016, and I HATE the way the scrollbars work. If you drag the scrollbar with the mouse, your current view freezes in place until you 'drop' the scrollbar. Then the screen suddenly jumps to this part of the spreadsheet. It used to actively display the spreadsheet as you dragged the scrollbar around, so you could see everything as you moved around.
I constantly work with enormous spreadsheets where I need to find specific sections quickly, and now that the scrollbar has become useless, it takes me much longer to navigate.
I understand you can use the arrow keys, or different shortcuts to jump through a spreadsheet, but I found the scrollbar very useful when moving through very large files. I can't be the only person who wants this functionality turned back on, but I can't find any information on it, or any settings I can switch.
This fix works for me. In Win 10 open Control Panel. Navigate to: Control Panel\All Control Panel Items\Ease of Access Centre\Make the computer easier to see. Near the bottom in the section "Make things on the screen easier to see" is a tick-box: "Turn off all unnecessary animations (when possible)". This was ticked for me by default so I unticked it and clicked the Apply button after which the scroll bar in Excel started to work as it does in Win 7, i.e. the cells in the background move as you drag the scrollbar left/right and up/down. Perfect.

What is QT-Creator's equivalent to WinForms Dock-Fill?

I have a QTreeView widget placed inside a QDockWidget:
I want to set the properties of the QTreeView, that it automatically fills the whole available client drawing area (similar as WinForms DockFill property).
How can this be achieved with the QT-Designer?
Note: I've been playing around with the QTreeViews sizePolicy properties. If these are set to Expanding (as is the default) the accepted answer works out out of the box.
In Qt Designer, right-click the dock-widget, and then select Lay out -> Lay Out Vertically from the menu. Or you can just click on the dock-widget to select it, and then use the equivalent layout toolbar buttons.
If you want to maximise the space taken up by the tree-view, select the first child widget of the dock widget (it will probably be shown as dockWidgetContents in the Object Inspector pane). Then scroll down to the bottom of the Property Editor, and reset all the margins to zero.

display the horizantal scrollbar always(even on empty) in CListctrl using vc++

background :-
I have 2 list control in my dialog wherein I am synchronising the vertical scroll with both of them. synchronising is fine but I have issue when the one of the clistctrl has the horizontal scrollbar and the other does not have. Since the scrollbar will consume some space inside the Clistctrl which will lead to mismatch the scroll position of the other when we are at the extreme bottom of the scrollbar.
I tried changing the styles of the list control in OnInitdialog() before populating the data but it is not working.
Can anyone provide the solution to my problem?
Thanks in advance!

VC vs VB6: Own-Drawn ListBox obvious vestigial while mouse wheel scrolling

On an Own-Drawn ListBox, I select index = 5 then I scrolling down items (let's say going to index 15) by mouse wheel,the item focus of rectangular frame has an annoying appearance with obvious vestigial moving from top to down instead of moving up. Is the own-drawn ListBox a common issue? My VB6 Listbox has such issue,A VC Project on CodeProject also has such issue. How to resolve this problem if it is not ListBox feature?
Manifest specifies common controls v6 solved the problem. I feel comfortable now.

Why is Excel / Word 2013 starting invisible?

Our Company recently upgraded to Office 2013 since we want to use SharePoint 2013.
We had several issues with the new Office Version but Microsoft has already solved some of them.
Anyways, one thing sitll grinds my gears:
Excel or Word sometimes starts invisible. It is visible in the Taskbar but the window doesnt pop up. I can click on the Icon in the taskbar but it doesn't change anything. The only way i figured out to show the window, is to use [Windows] + [Arrow Keys].
I can't tell the constellation why this is happening but most of the time it is if there isn't already another instance of the program running.
I don't have Office 2013 at home to reconstruct this but I have seen this on different Computers at our Office.
Now does anybody know about this issue?
What can I do about it?
Is it known to Microsoft?
Any help is appreciated.
I don't think that it's invisible, it's just starting off screen somewhere. Perhaps on a second monitor that is no longer there (or moved virtually to the other side). The [Windows] + [Arrows Keys] just moves the window onscreen where you can see it.
Alternatively, you could hover the mouse over the icon on the task bar, right click on the preview window and then select Move (if Move is grayed out, select restore and repeat). Then, hit any [Arrow Key] (this will attach your mouse to the window caption bar) then move your mouse (without clicking anything) until the window shows up on screen.
By doing this you can figure out what side of the screen the application is opening up (not that knowing helps much). Excel should just show up where ever you had it last, but it will not remember it's location if you snap it to the sides or top of the screen (which is what you were doing); It will only remember the Normal View size and position of the window.
My workaround for this bug is to click the Taskbar icon for the new (invisible) window while it's active, which minimizes the window, then click it again to restore it. Then it becomes visible.
I have the same issue, and it's definitely an invisible window, not off-screen (see workaround below).
It only happens in specific circumstances: when opening a second word doc from a sharepoint/office 365 location, the second doc gets a taskbar icon, but no visible content, so the first doc is still visible (but the second doc is invisibly in front of it).
The workaround is to click the minimise button on the first doc. Nothing will appear to happen because it's the invisible second doc window that receives the click event. Then select the icon on the task bar to make it reappear, properly visible.
