I'm testing some signals with GTK+ 2.0. I'm looking for a way to get a signal emitted when I click on a GtkEntry. if (widgets_info[i].action & IG_INPUT) { widget->frame[i] = gtk_entry_new_with_max_length(MAX_INPUT_LENGTH); gtk_entry_set_text(widget->frame[i], widgets_info[i].text); catch_signal(widget->frame[i], MY_SIGNAL, &change_entry, widget); } I have a pre-selected text in my entry ( widgets_info[i].text ) and i want this text to disappear if the user click on my GtkEntry. Does someone know what is this signal? (Sorry for my English) Try focus-in-event , note that you must enable focus

I set NSButtonCell as a cell type in a Table Column in my NSTableView . I implemented an IBAction method, but I can't wire it with NSButtonCell in IB - the wire don't want to highlight a button from NSTableView . How to connect a method with NSButtonCell ? Or maybe there'se another way to handle its click event? Thanks You should be able to wire up a connection from the cell by control+dragging to any object in your NIB. Just make sure the cell is actually selected, and that your action is defined as an IBAction in the object's header file. In your action method you can determine which row was

I'm looking to send a mouse click to a specific position on a screen without affecting the mouse cursor's location. I've scoured and have tried everything under the sun with mouse_event (which is supposed to do this) mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0); However this ends up only sending a mouse click to wherever the position of the mouse is. So I end up having to move the mouse to get it to work. Cursor.Position = new Point(X, Y); Anyone have any idea how I can do this WITHOUT having to move the mouse? I've also tried the following code block with no success as

I am trying to have different behaviours when single clicking and double clicking the wpf Image control. Unfortunately the single click is fired first, so the double click is ignored. If you use the MouseDown event instead it has a property in the EventArgs for ClickCount . This allows you to know how many times the user has clicked on the control within the system's double click time span. You can probably use this to implement your own logic for deciding between a double and single click. You can check double clicks using ClickCount property in the event args. if(e.ClickCount == 2) { // Do

I want to create a pop-up menu, which will appear if i right clicked on the canvas . How can I do this? which function should i modify? Any help would be appreciated. Following code will create a popup menu when right-clicking either on the vertex or on the canvas... /** * a GraphMousePlugin that offers popup * menu support */ protected class PopupGraphMousePlugin extends AbstractPopupGraphMousePlugin implements MouseListener { public PopupGraphMousePlugin() { this(MouseEvent.BUTTON3_MASK); } public PopupGraphMousePlugin(int modifiers) { super(modifiers); } /** * If this event is over a

I am developing a web application and using quite a lot of JavaScript doing tasks. I have quite some tags that are bound with Jquery click to do some jobs, so I have code like this: html code: <a href="#" id="id1">some content here</a> <a href="#" id="id2">some content here</a> .... Jquery code: $('#id1').click(function(){ //do something here.. return false; }); $('#id2').click(function(){ //do something else here.. return false; }); with this approach, when the script runs, jquery must look up the selectors (id1,id2, ect). but there is another approach which avoid looking up selectors , this

I've found strange behavior of jQuery click event. If we are using keyboard navigation (accessibility case), click is launched by Enter or Space (it depends, which HTML element we are using ). There is a test page on jsfiddle, You could try to navigate with keyboard in Result frame, and click is launched in different situations : http://jsfiddle.net/DCXhN/9/ In jQuery manual, I have found following description of click event : "The click event is sent to an element when the mouse pointer is over the element, and the mouse button is pressed and released. Any HTML element can receive this event.
