gtk#

问题 I may need to build a GTK GUI using C# and Mono. If I understand correctly, that means I have 3 choices: Write the C# code to call the GTK# wrapper classes. GUI is "in the code". Use MonoDevelop GUI designer. This builds an interface using the stetic markup. I appears to just be XML. Use Glade and libglade to create the GUI and load it at runtime. I have a little experience with MonoDevelop's GUI editor. It's nice, but has a few rough edges. I can imagine needing to hand edit the stetic

问题 Im trying to manipulate an image using system.drawing in GTk#.I want the UI to update the image on screen as soon as the user updates a textbox.To implement this i tried using the background worker from winforms,it worked but when the textbox is updated at a higher speed the application becomes stuck with no error. So i took a look at multithreading in GTK here http://www.mono-project.com/docs/gui/gtksharp/responsive-applications/ and created a thread . void textboxchanged() { Thread thr =

问题 In a GTK/GTK# TreeView , how do I get the item/node which the mouse pointer is currently hovering over? 回答1: Let's say we want to select items using the right mouse button without using checkboxes. The following ButtonPress event handler does just that - it toggles the selected property of the item we have clicked with the RMB. We then use CellDataFunc s to highlight the selected items. tv is the TreeView, store is the underlying ListStore. [GLib.ConnectBefore] void

问题 I need to change GUI theme in GTK#. I tried something, but it is still far from ideal. Here is my code: string Resource_File = "Black-Diamond\\gtk-2.0\\gtkrc"; Application.Init (); if (System.IO.File.Exists (Resource_File)) { Gtk.Rc.AddDefaultFile (Resource_File); Gtk.Rc.Parse (Resource_File); } else { ; } MainWindow win = new MainWindow (); win.Show (); Application.Run (); Output: That's ok, but not what I expected(some elements don't look like in original theme). Can you tell me how I can

问题 Im trying to change the color of button widget in GTK# by using button1.ModifyBase(Statetype.Normal,new Gdk.Color(1,1,1)); This is called from another button click event,but the widget color is not updated why is this? 回答1: Instead of the 'flaky' ModifyBase, you can just use the ModifyBG method, same params are passed. button1.ModifyBG(Statetype.Normal,new Gdk.Color(1,1,1)); BTW, I say flaky since you are dealing with GTK2.x under Mono GTK# and there are tons of issues on both sides when it

问题 Can anyone tell me how to right align the numbers in a GTK# spinbutton control? I can't for the life of my figure out how it works there. The documentation is sparse, and I'm just drawing a blank after numerous attempts. Thanks in advance for any responses. 回答1: It's a subclass of Gtk.Entry - you should just be able to set the Xalign property to false. 来源： https://stackoverflow.com/questions/11284994/how-to-right-align-numbers-in-gtk-spin-button

问题 Using Windows Forms or WPF I can open a dialog window by calling ShowDialog. How can I do that using Gtk#? I tried just making the Window modal, but although it prevents the user from interacting with the calling window it does not wait for the user to close the dialog before running the code after ShowAll(). 回答1: Instead of using a Gtk.Window, use Gtk.Dialog, then call dialog.Run (). This returns an integer value corresponding to the ID of the button the user used to close the dialog. e.g.
