How to Scroll Parent wxScrollWindow from Inside Child wxScrollWindow in wxWidgets
Hi i am using wxScrollWindow and have 2 wxScrollWindows. Both of them works correctly individually.
- First wxScrolledWindow scrolls horizontally, and the second scrollWindow scrolls vertically.
- First wxScrolledWindow has the second scrolledwindow embedded inside it. Screenshot for illustration purposes is attached below.
The problem is that when I am inside the second scrolled window(vertically) then I am unable to scroll horizontally. In the screenshot the second scroll window contains buttons ranging from button1 to button20 lets say. So I am able to scroll vertically through these buttons. Similarly the first scrolledwindow has many wxPanels that are horizontally scrollable. The problem comes when I try to scroll horizontally when the cursor is on top of any of the buttons. So to scroll horizontally I have to first move the cursor to any of the labels(shown in screenshot as label1 upto label5) and then start horizontal scrolling. How can I also enable horizontal scrolling when the cursor is on top of any of the buttons. I am thinking of forwarding the child scroll event to parent(first) scrollwindow using event.Skip() but I don't know for sure how that will work. The buttons shown in the screenshot are inside a wxScrolledWindow which scrolls only vertically. So when the user tries to scroll the buttons horizontally they don't move as expected. But i want that the parent scrollwindow should be moving(scrolling) when the user tries to scroll the buttons horizontally.
I have resolved the issue by writing my own custom event class which derived from wxEvent and everything is working now as expected. That is, I am able to control the scrolling of the parent scrollwindow(horizontal) from within the child scrollwindow(vertical).
