How to grab and hide cursor using gtkmm? -


I'm trying to write an application using gtkmm, and I want to hide it from the mouse cursor when focus So the first step I have taken is to hide the mouse cursor when the cursor is above my window, which is successful. But when the mouse is taken out of my window, to prevent it from showing, then I restrict the mouse movement with the mouse cursor back to the center of my graphing area.

To do this I need to know the status of window and the window size, which is easy to use: GDK :: Window :: Match-item and GDK :: window ::. However, if the window is moved, the matching status will not be updated and thus my cursor will fall in the wrong position!

So what are the options for the effect that I can get here?

simply indicator. 

  // Let windows pass all events separately LEAVE_NOTIFY_MASK MainWindow- & gt; Set_ivents (Gdak_akspozr_mask | GDK_pointr_moshn_mask | GDK_pointr_moshn_hint_mask | GDK_btn_moshn_mask | GDK_buttonl_moshn_mask | GDK_button2_moshn_mask | GDK_button3_moshn_mask | GDK_btn_pres_mask | GDK_btn_riliz_mask | GDK_ke_pres_mask | GDK_ke_riliz_mask | GDK_antr_notifai_mask | GDK_foks_chenj_mask | GDK_strccr_mask | GDK_proprti_chenj_mask | GDK_vijibiliti_notifai_mask | GDK_proksimiti_in_mask | GDK_proksimiti_aut_mask | GDK_substrkture_mask | GDK_scrol_mask | GDK_tc_mask | GDK_smuth_scrol_mask | GDK_toucpd_jescr_mask); MainWindow- & gt; Set_modal (true); Auto display = main wands-> gate_desplay (); Auto Window = Main Window- & gt; Get_window (); Auto drag success = display-> Get_default_seat () - & gt; Catch (window, gdk :: SEAT_CAPABILITY_ALL, true); If (hurry! = GdK :: GRABICAS) {std :: clog & lt; & Lt; "Failed to grab:" & lt; & Lt; Bandesut & lt; & Lt; Std :: endl; }

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
