254 Day 7 NOTE 1. Choose Edit | Cut from the main menu. The Code Editor comes to the top, and the EditCutClick() event handler is displayed. 2. Type the following at the cursor: Memo->CutToClipboard(); And that’s all there is to that particular menu item! You may not fully realize it, but VCL does a lot for you behind the scenes. The whole idea of a framework is to take the burden of the low-level details off the programmer’s back. Life is good. One of the interesting aspects of a program like C++Builder is that you rarely view your program as a whole. C++Builder conveniently takes you to the section of code you need to work on to deal with a particular event, so you usually only see your program in small chunks. Listing 7.1 contains the header for the ScratchPad program up to this point. The header is entirely C++Builder generated. The entire SPMAIN.CPP program is shown in Listing 7.2. Follow the examples you’ve just worked through to write code for each of the remaining menu items. Copy the code for each of the menu OnClick handlers from Listing 7.2. (The comment lines are there to explain to you what the code is doing. You don’t have to include them when you type the code.) Listing 7.1. SPMAIN.H. The event handlers appear in the source file in the order in which they were created. Don’t be concerned if the order of the event handlers in your source file does not exactly match Listing 7.2. The order in which the functions appear makes no difference to the compiler. 1: //------------------------------------------------------------ 2: #ifndef SPMainH 3: #define SPMainH 4: //------------------------------------------------------------ 5: #include 6: #include 7: #include 8: #include 9: #include 10: #include 11: #include 12: #include 13: #include 14: //------------------------------------------------------------ 15: class TScratchPad : public TForm 16: {
