It can lay out controls in either a single rectangular column or a row. Sizers can then be nested inside each other to create more complex layouts. In this recipe, we will explore some of the basics of using BoxSizer to layout controls on a panel. How to do it… For this recipe, you need to perform the following steps: 1. choice) 2. AddStretchSpacer() 3. choice) 4. CENTER) 5. SetSizer(sizer) 6. The last step in this recipe is defining the event handler for the Choice selection. Layout() 47 UI Layout and Organization How it works… First, let's take a look at a graphical breakdown of the layout that was produced by the Sizers that we used in the _doLayout method: The preceding image tries to label the areas that are being managed by items added to the Sizer.
This is because the EVT_TOOL event is the same as EVT_MENU, so all tool events will automatically be routed to the already existing menu handlers for the same actions. 1, the ToolBar object now supports adding a stretchable space between tools by calling the AddStretchableSpace method, which makes it possible to align tools away from the left side of the ToolBar object as the parent window changes its size. 41 Common User Controls A ToolBars object also supports adding several other types of tools in addition to the normal icon button-based ones.
Using the MenuItem constructor or the kind parameter of the Menu class' Append method, a MenuItem object can have either a CheckBox (ITEM_CHECK) or a RadioButton (ITEM_RADIO) control.
