I wish this help you The event will continue to bubble up the container chain if you return false
code :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:onClick="layoutClicked" >

    <Button
        android:id="@+id/button1"
        android:onClick="myButtonClicked" />

</LinearLayout>

should help you out If you return false from the submit event, the normal page form POST will not occur.
In Postgresql, after grouping, return false if any value of a column is false. If all values are true/false, then return

seems to work fine An alternative to using the bool_and operator would be regular conditional aggregation:
code :
SELECT
    name,
    COUNT(*) AS count,
    CASE WHEN SUM(CASE WHEN !istasty THEN 1 ELSE 0 END) > 0
         THEN FALSE ELSE TRUE END AS result
FROM apple
GROUP BY name;

Hope this helps The OnInitDialog() member function is called by the MFC framework when it is processing a WM_INITDIALOG message.
The purpose of this member function is to provide a place to perform any special initialization of the dialog's controls and interface.
code :
BOOL CSimpleDlg::OnInitDialog() 
{ 
   CDialog::OnInitDialog(); 

   // TODO: Add extra initialization here 
   m_cMyEdit.SetWindowText(_T("My Name")); // Initialize control values 
   m_cMyList.ShowWindow(SW_HIDE);      // Show or hide a control, etc. 

   return TRUE;  // return TRUE unless you set the focus to a control 
   // EXCEPTION: OCX Property Pages should return FALSE 
}
What is the difference between (if (x == y) return true, else false) and (if (x != y) return false, else true)?

wish helps you There is no difference and mostly you can do whatever you like.
Please keep in mind that you do not need to compare boolean values with true and false cause they are already okay for the condition. For example

To fix the issue you can do return true means you handled it (consumed the long click event), return false means you didn't handle it so the event is up for grabs by the next eligible View in line.
The documentation explains this in other words:
