问题 Using imgAreaSelect, I'd like to restrict the area that is being selected directly while selecting. The reason behind that is that I display a graph and the image includes the legend and the axis. I want to select only the graph area to later reload the graph zoomed on that area. So when the user is selecting an area on the image, the selection should not go outside certain bounds. Is this possible? Thanks! 回答1: The documentation tells me that you can set the coordinates of the selection area

问题 We try to achieve the following: When a node gets selected in a JavaFX TreeTableView , also "the path to the root", i.e., the parent, the grandparent, and so on should get selected. Selected in this case means highlighted with a different background color , see the image (in the example, the node on Level 2 has been clicked by the user). Is there a built-in function how to achieve this? We tried using CSS but did not succeed. 回答1: There's no "built-in function" to do this. Use a row factory

The ViewPart with the Toolbar-Command only contains one Child (a TreeView ) and does this.getSite().setSelectionProvider(child) in it's createPartControl(Composite) -Method. The problem is, that when i click one of the other ViewPart s in my Perspective the Command gets disabled, but the selection does resist in the TreeView

问题 I was wondering if there was any way to hide which cell you have selected within excel (for presentation purposes). I want the cursor itself (to navigate), but I want the box that highlights which cell i am clicking on invisible if possible. Thanks! 回答1: If you're using a button object on your worksheet, it shouldn't highlight any cell. If you're using a cell as a "button", your best bet would be to hide and not use column A on your worksheet and then create a module: Private Sub Worksheet
