I have a custom QAbstractListModel and I use it for ListView to show images. My question is how can I add red tick (as shown in the picture) on specific items without changing original image?

I have a ListView inside of a TornadoFX form builder field that can be added to and removed from by some buttons off to the side. However whenever the contents of the list is modified from the buttons, the list moves vertically downwards. The height of the ListView remains the same, but it's almost as if there is padding being generated along the top whenever the content length is modified. The height change is then reset as soon as there is some change in focus, either by clicking on another component in the view, or by unfocussing and refocussing the window.
I've tried to limit the ability for this to happen by enforcing a max height, both on the form field and on the ListView itself, but neither worked.
Using listeners to print out all the values I could think of that would result in this change, I found that the "bounds in Parent" were changing, adding a value of 17 to both the minY and maxY values. I've not been able to determine where this value of 17 comes from.
The current code for the view is here: https://pastebin.com/6qFVvxvP
I also have some images to help visualize what the problem is:

I am working on a Qt-UI with PyQt and found this nice snipped to create a custom collapsible box widget here: How to create collapsible box in PyQt
I have just replaced the internal QScrollArea by a QFrame.
It works perfectly, as long as the content of the layout that is added stays the same.
However, I allow the user to add or remove widgets from that layout dynamically during use. Here I need some help. I am adding a Grid Layout with, say, 3 widgets inside there (initial creation of the box with .setContentLayout) and once the user adds a 4th widget:
the layout is compressed and keeps its original size
all widgets inside are compressed to fit in the newly created one
overall size of the collapsible box is kept constant.
I have played with various options like updateGeometry() on the content_area and all surounding widgets. It seems I don't fully understand what this code does, I am not really familiar with these animations yet. My best guess is, that the animation somehow blocks the update of the height of the collapsible box, causing the layout to be compressed.
I would be really happy for a pointer where to look / what to adjust to get the size of the collapsible box reacting to the size of the containing layout.
Thanks!
I am trying to get 2 listview objects to work on a powerpoint slide. I can place them anywhere on the slide, but when I start the slideshow, 2 smaller copies appear in the upper-left corner. Text added to the listview appear in the upper-left boxes. I can't select the original listview either.
How can I prevent the 2 copies from showing up so I can work with the listviews I positioned on the slide?

I looked into it a bit, and I think it's just a glitch with the Listview control.
From my tests, the actual Listview control was smaller then the original, but the top left position was correct (after the first time in reading/presentation view). I assume the they are smaller because it doesn't have a zoom property, and the slide is stretched to fit the window.
If you really want a Listview...which I hate to call into question, but think is warranted...then you can just Insert a Rectangle without a border over the Listview control to hide the original placeholder. The real Listview will still get drawn on top.
I think this is just the beginning of your troubles with a Listview control in PowerPoint...are you sure that you need it. Maybe linking to an Excel file with the Listview would be better, or some use of animation.
I'm trying to create a live tile for my application, using a user control.
The user control contains a grid, an image and a rectangle filled with color.
Now here comes the funny part.
I want the rectangle to act as a background for the tile's title, and the image to fill the rest of the tile. And i said to myself, well, lets put some rows in that grid and set the like you usually set them in a WPF/SL application.
I then write the entire thing in a WBM and save it to isostore.
The problem is, the parser seems to ignore the presence of grid's rows. regardless of what I try, the rectangle is not shown, and the image covers the full tile, when it should only cover the first row. It is as if the grid didn't even existed.
Another funny aspect is that it doesn't matter if I use rows or columns, the result is the same.
Any ideas?
Are you using the following method?
Dynamic LiveTile - adding background image?
I recently implemented a Live Tile using a Grid with Rows and Columns for layout of some TextBlocks. I encountered similar challenges, so I placed the control that I was using for my Live Tile on a blank page in my app to better see what was happening. Does the control render correctly when displayed on a page (versus being rendered to a WriteableBitmap)?
Another idea. Instead of trying to position the Rectangle relative to the tile's Title, why not leave the Title property blank and put the same text in a TextBlock within the user control?
If you are careful about the font and positioning of the TextBlock, the text on the resulting background image can appear indistinguishable from text displayed from the Title property. I decided to follow this strategy myself. I found the font information in the following answer:
Font size and family for a tile's title
Otherwise, could you post an example of the XAML you are using?
In my .net windows form (I am using XP Pro SP3 and VS 2010), I have created a menustrip. In the menustrip are several menu items, each with a dropdown menu. The menu items in the dropdown menus each have an icon with some text. I want to make the menu more compact by decreasing the horizontal space between the icon and the text. (I added a red arrow to the picture to show the space I am talking about).
So far, I have set the padding of all the menuitems to 0, but this seems only to affect the vertical spacing between one menu item and the next.
I want to use the system rendermode for the menustrip (although the problem persists no matter what rendermode I use. The icons in the menu are 16x16, and have the property sizetofit.
Funny thing is that this very same spacing is just the way I want it in the menustrip - the icon is right next to the text.
This will remove the image margin completely, but it removes the images too; I just want to change the width of the image margin.
For Each menuItem As ToolStripMenuItem In menu_main.Items
DirectCast(menuItem.DropDown, ToolStripDropDownMenu).ShowImageMargin = False

What can I do here?
So, this is kinda cheating, and probably isn't going to look as clean as you'd like, but I was able to do it by making the image have the text and then setting following properties in the designer for the menu item:
DisplayStyle = Image
ImageScaling = None
