Delphi - How to prevent Forms/MsgBoxes to move under prior form?

阅读更多关于 Delphi - How to prevent Forms/MsgBoxes to move under prior form?

问题 Many times after the Windows 98 era we have experienced that some dialogs lose their Z-Order and move back to the prior form. For example: Dialog1.ShowModal; Dialog1.OnClickButton() : ShowMessage('anything'); When MessageBox appears, it sometimes doesn't have focus and is moved under Dialog1. The users are confused about it, they say: My application froze!!! But if they use Alt+Tab to move to another app and back, the focus returns to the MessageBox and it will be the foreground window. We

Google Maps v2 Marker zOrdering - Set to top

阅读更多关于 Google Maps v2 Marker zOrdering - Set to top

I know there are a few threads around on this topic but i havent yet found a good enough solution. I NEED to place a marker over the top of all other markers. How do i do this? I have tried adding this marker before and after all other markers, however the ordering seems to be from bottom (front) to top (back) on the map view. This is not acceptable as I want to center on a marker which is in front of all markers. I know that Polygons can be zOrdered but I would MUCH prefer a nicely styled graphic! In-fact you can't order a Polygon over a marker! "The order in which this polygon is drawn with

问题 How do I set Z-order for VBox in JavaFX? 回答1: Z-order in JavaFX is actually the order in the scenegraph, eg. in the content sequence of the scene (then in the contents of the groups, containers, etc.). All nodes have also toFront() and toBack() functions to help changing this order. For finer control, you have to remove nodes from one place and insert it higher or lower in the sequence. 回答2: With the toFront() and toBack() functions you can indeed influence the z-order, but be aware that this

问题 Folks, Please does anyone know how to show a Form from an otherwise invisible application, and have it get the focus (i.e. appear on top of other windows)? I'm working in C# .NET 3.5. I suspect I've taken "completely the wrong approach"... I do not Application.Run(new TheForm ()) instead I (new TheForm()).ShowModal() ... The Form is basically a modal dialogue, with a few check-boxes; a text-box, and OK and Cancel Buttons. The user ticks a checkbox and types in a description (or whatever) then

How to set Z-order of a Control using WinForms

阅读更多关于 How to set Z-order of a Control using WinForms

I'm writing a custom TextBox that upon gaining focus changes its border style. As adding a border causes the control to overlap with those neighbouring it, I temporarily bring the text box to the front of the dialog (using textBox.BringToFront() ). However, once editing is complete and focus is lost, I would like to send the control back to its original position in the Z-order. Is this possible (preferably in a simple way!) Call the GetChildIndex and SetChildIndex methods of the parent's Controls collection. There is no Z-order as there was in VB, but you can use the GetChildIndex and

How to get the z-order in windows?

I'm making an application where I interact with each running application. Right now, I need a way of getting the window's z-order. For instance, if Firefox and notepad are running, I need to know which one is in front. Any ideas? Besides doing this for each application's main window I also need to do it for its child and sister windows (windows belonging to the same process). You can use the GetTopWindow function to search all child windows of a parent window and return a handle to the child window that is highest in z-order. The GetNextWindow function retrieves a handle to the next or
