I have a datagrid that always show the clr-dg-placeholder even if I did not ask for it.
Is there a way to avoid having it displayed? Right now, if my grid has only one line, I can see a second one that corresponds to the clr-dg-placeholder item.
Thanks

I have a list of lets say 20 buttons (this number can change dynamically) in a listView which I want to display using a grid on a swipeView or gridView. Only 6 buttons should be visible at once. In addition, it should be possible to exchange the position of buttons via drag and drop (see http://doc.qt.io/qt-5/qtquick-draganddrop-example.html). In case gridView is the way to go, is it possible to have it behave like swipeView, so that the buttons can not be moved to an arbitrary position but lock onto their column?
You might want to give snapMode a try.
You have the choice of:
GridView.NoSnap (default) - the view stops anywhere within the visible area.
GridView.SnapToRow - the view settles with a row (or column for GridView.FlowTopToBottom flow) aligned with the start of the view.
GridView.SnapOneRow - the view will settle no more than one row (or column for GridView.FlowTopToBottom flow) away from the first visible row at the time the mouse button is released. This mode is particularly useful for moving one page at a time.
You need to make sure, that the size of the GridView really fits your desired amount of delegates, for it will only make sure, that the first element is aligned, not that there is no element paritally protruding the view.
For some reason I need to overlap 2 report elements in BIRT. For example I need to put 2 labels one on top of another. Is this possible in BIRT? I am using BIRT 4.3. Normally when we place elements in report designer each item is occupying one full row. Some times i need to overlap elements and sometimes i need to place elements side by side. side by side can be achieved with Grid but I am not sure how to overlap report items? Please help and thanks in advance.
You can put two labels in the same cell of a graph or table, then define when to "hide element" with the "Visibility" property.
OR
In order to have both display at the same time, you can use a grid to define where the top label will go, then add the back label as an image using the background (advanced property)
I'm trying to make a Flex (Advanced)DataGrid component with some mechanism where the user can toggle the visibility of the columns. I've crudely implemented this by reading in the columns into the right-click menu, and when a column name is selected here, the visibility is toggled. It works, but it's not the most elegant solution.
Specifically, I'm trying to emulate the "datagrid" that Mozilla Thunderbird uses to display emails. Here is an image:
In the upper right, there is an icon over the scroll bar. If there is no scrollbar, the icon remains in the same place. When clicking the icon, it opens up a menu that shows all the possible columns, with the visible ones having a check mark next to them, like this:
Also, the scroll bar always appears under this button, never "pushing" it over into it's own column.
I'd like to re-create this in Flex. I believe the menu part and creating a column with a button headerRenderer is easy enough. But I can't figure out how (if at all possible) to do this with the scrollbar, because the scrollbar always seems to be "its own column". Any ideas or help would be appreciated. Thank you.

One dirty solution comes to mind. Create a component based on Canvas, then add an AdvancedDataGrid by overriding createChildren. Override updateDisplayList as well and add a button like the one in Thunderbird to the upper right of the Canvas. This will cause the button to appear over the DataGrid. Problemo solved?
I have a question concerning Tree items. I want to show where a drop action would be placed... The item will be placed in between two existing elements. So what I want to do is, to take the upper item and draw a line underneath it. But I struggling to address the itemRenderer...
I have the index for the itemrenderer, but I dont get a instance of that object.
Any help is appreciated!

If you're doing drag & drop right, it should be showing a line where you are going to drop the dragItem. That is standard behavior. You shouldn't have to do that in the itemRenderer.
I would like to use the selectionMode=multiple described in the Flex docs, but with a few modifications:
1) I would like the box that the user drags over the graph to remain there until the user drags a new one.
2) In the top right corner of the box I want to display the sum of the items selected by that box.
Does anyone have any examples of this or something similar?
If not, what's the easiest way to implement this?
