Hello Folks, I have been trying to figure out how to, at runtime, create a variable number of new tabs in a TabStrip, populate those tabs with Controls, and then be able to reference those controls, all dynamically.
There seems to be little information available as to how to 1) dynamically create controls, and 2) reference dynamically named controls after creation. Even with just a simple experiment, I cannot get a GridView to display in a new tab. The Form has been given, at design-time, a TabStrip and two buttons. The tabs are 'closable'. One button, 'btnAddTab', creates a new tab and a GridView with the new, current tab as parent. (At least that's what I think it is doing.) The other button, 'btnTabInfo', displays info about the currently selected tab. And, I am assuming the GridViews need to have unique names. [code] ' Gambas class file Public Sub btnAddTab_Click() Dim hGridView As GridView TabStrip1.Count += 1 TabStrip1.Text = "Tab " & TabStrip1.Index hGridView = New GridView(TabStrip1) As "GridView" & TabStrip1.Index hGridView.Show TabStrip1.Refresh End Public Sub btnTabInfo_Click() Print TabStrip1.Children[0].Name Print TabStrip1.Children[0].Enabled Print TabStrip1.Children[0].Visible End Public Sub TabStrip1_Close(Index As Integer) TabStrip1.Index = Index ' TabStrip1.Current.Children[0].Delete() 'Comment out to test if tab is empty TabStrip1.Current.Delete() End [/code] Tab creation works, but the GridView control does not display. Any attempt to close a tab without first deleting its children causes an exception, showing that the tab is indeed being populated with a child control. Clicking on btnTabInfo for "Tab 1" gives: GridView1 True True So, the program is doing at least some of what I've told it to. I'm obviously not telling it the right thing. How does one: 1. Create new controls and make them visible? 2. Reference new controls after creation [ie. (de-)reference a string as a the name of a control]? -- Lee ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user
