Re: Error in Tutorial? - Part 2Posted by webmaster Guido on April 09, 2002 at 17:47:50: In Reply to: Error in Tutorial? - Part 2 posted by p12221 Robert Burko on March 29, 2002 at 18:43:46: : Along with my first posting for "Error in Tutorial?", the form unicoen1/unimain.dfm needs to be updated so that BtnVolConvert: TButton and RGVolume: TRadioGroup has an event OnClick. EdVolume: TEdit needs an event set for OnKeyPress. This will create the necessary procedures. : Also, the comment in ConvertVolumeShow is incorrect. Instead of "Number of decimals depends on selected button in RADIOGROUP RGVolDecimals" it should have RADIOGROUP RGDecimals. There is no radiogroup RGVolDecimals. ------ Thanks for the remarks. The original idea was to also add a radiogroup for the number of decimals for the volume conversions, and this should have been "RGVolDecimals". Later on, I decided for only one radiogroup, as can be seen in Unicoen2. As for the missing event-handlers: these are not "errors", it's meant to be that way. In the text of lesson 9, it says: "...and see for yourself: it does absolutely nothing, because you have to fill in most of the coding". See also: my answer to your previous posting. |
