北城以北 提交于 2019-11-28 03:15:49
问题 I have a JTable and its TableModel, it works well but what I want to do now is to get the selected cells of it. I thought of doing something like : int rows = this.getTable().getRowCount(); int columns = this.getTable().getColumnCount(); for(int i = 0 ; i < rows ; i++) { for(int j = 0 ; j < columns ; j++) { if(table.getCell(i,j).isSelected() //... } } But of course something like this doesn't exist. What should I do instead? 回答1: In JTable, you have the JTable.getSelectedRow() and JTable

WPF ListBox Image Selected the saga continues

人盡茶涼 提交于 2019-11-27 19:32:59
Ok in my ListBox scrolling images w/ text, etc. the saga continues. When I click one of the items, to select it, that runs a process to open a web browser and go to a specific URL. The problem I'm having now is that when the WPF app loses focus, and the web browser opens, the item clicked inside the listbox turns white. Here's the whole ListBox XAML. I have set the selected items to transparent, so does this have something to do with the WPF app losing focus? Is there something I can add tom the code that runs the process to open the web browser to set focus back to the WPF app? Thanks.

自作多情 提交于 2019-11-27 13:34:07

Set ComboBox selected item highlight color

与世无争的帅哥 提交于 2019-11-27 08:25:16
I need to change the highlight color of a ComboBox's selected item in the popup list. I've found several tutorials explaining how to do this, but all of them either use Blend, which I do not have and cannot obtain, or involve changing the system default colors--which seems like a hack to me. Can someone point me to the template I need to override, or tell me the property I need to set? Kent Boogaart Override the SystemColors.HighlightBrushKey (and SystemColors.HighlightTextBrushKey if you want): <ComboBox> <ComboBox.Resources> <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}"
