When I click on a non-reactive area of a win32 window in the foreground (for example, a blank space on a menu bar) and drag the mouse off, background windows do not receive mouse events. Buttons don't got into hover state, the cursor doesn't change, etc. The mouse is "captured" by the foreground window, although it doesn't receive messages either unless the mouse is over it. This state persists until I release the mouse button. Why is this, and how can I get out of this state programmatically without releasing the mouse button?
Researching this issue, I thought at first it was related to the concept of mouse capture, but it appears it is not. GetCapture() returns NULL during this state, whatever it is.
Clarification Edit: This is easy to see in the simplest of applications. Create a new Win32 project in Visual Studio with the default project template, which makes an empty window. Run it, and click and hold the blank inside of the window. Drag the mouse outside the window, and note that no buttons in background windows light up or otherwise respond to mouse-over events. Even if I stick ReleaseCapture() in the WndProc so that it fires after every message, the result is the same. It really seems like this has nothing to do with mouse capture in the Get/SetCapture sense.
My task is to implement a file upload form in a popup sub-menu panel. I am using XmlHttpRequest, so it's important to keep that popup opened until I receive an event status that file loading completed/failed. Onmouseover and onmouseout events are used to show/hide the popup.
On "hide" the popup panel is detached from the DOM, and cannot be used anymore as a listener for XHR events.
When I click form's "Browse" button, a system dialog window is opened above the browser. In IE, Chrome and Firefox in Windows the system dialog disables events handling by page. Which means if you move a mouse cursor out of the dialog window on one of the page element, the page won't do anything like reacting on mouseOver/mouseOut events. Unfortunately, in case with Chrome/Firefox on Mac (Safari is OK) the page elements do react on mouse over/out. And my popup menu becomes closed (due to mouseOut event handler for the popup) -> XHR response is not managed properly.
Assuming having an upload form in a popup is a must, what are the possible ways of keeping that panel/form visible while system Upload File dialog window is up? Probably a Mac specific solution.
Sample code can be seen here http://jsfiddle.net/xqvXG/
Solved this by freezing popup panel and covering the whole page with transparent div ('glass').
In case if user chooses file(s) and upload starts, I remove the glass and unfreeze the popup using the XHR function readyStateChangeHandler (or may do that in handler of load event).
If user clicks Cancel in system dialog window or closes it with "X" button - no events passed to the page and 'glass' remains on screen. Then any click on the 'glass' causes its removal and unfreezing (or simple hiding) the popup menu.
'Glass' is required to make a single one-click point (panel) for unfreezing the popup in case if Cancel/Close were pressed.
I wouldn't say this is a perfect solution (sometimes required extra action), but very close to what I was looking for.
I am working on a wxWidget-based application. On the Mac, I am trying to open a progress bar dialog on a modal dialog, but it goes behind my modal dialog. While the progress dialog is there, I am not able to perform any operations in application, so functionality-wise it is correct, but I want to bring it to the front, or send my modal dialog behind?
I would really appreciate if someone can point to some code reference as I am new to the Mac API.
Doing wxWindow::Raise() worked for me. Also make sure the progress dialog's parent is your modal dialog. With that said, putting the progress bar in the dialog itself would be a lot more slick.
I am implementing Drag & Drop in windows application. I have
Main Form (Has a toolbar with Search, Open, Print etc) - MdiContainer
On Search - Open a child - Search form.
Drag and Drop a file to a Grid on this search form.
In DragDrop event of the Grid - Call a Modal form.
I am having trouble here.
When i drag and drop a file on to a selected record in the grid, i am able to call a modal form in Grid_DragDrop event. But this modal form blocks everything until it is closed instead of just blocking access to the application. Also when i move this modal form around, i see trail of form moving and it does not go away until i close the form.
I am able to call the same modal form on a button click and able to move it around. No trail of form and it refreshes fine. It only blocks the application and not the desktop.
I am clueless about why this is happening only when i call modal form in DragDrop event?
Showing modal forms from DragDrop event is REALLY bad idea. Basically you make your app go haywire because it cannot do what windows require of it during DragDrop (including redrawing both DragDrop source (desktop?) and target).
Use DragDrop event ONLY to register what is being dropped and then process it afterwards.
I write a MFC application and need a button which is not taling the input focus away from another window.
Removing the WS_TABSTOP style does unfortunately not help when the use clicks the button with the mouse. When i block WM_LBUTTONDOWN i don't get a visual pressed indication so this doesn't work either.
If there is a specific window you want to keep the focus, you could just force the focus back to your window using the CWnd::SetFocus() command in your button's OnLButtonDown handler.
If you want the focus restored to one of several windows, you could try subclassing CButton and trapping the CWnd::OnSetFocus() message which is sent when the keyboard focus changes to the button.
The OnSetFocus() event includes a CWnd of the control that just lost the focus, so you could manually put it back, either as part of the OnSetFocus() event itself, or later as part of the OnLButtonDown() handler again.
