Many peo­ple who work with Direc­tor, use also Flash. Some of those who use Flash, write exten­sions for it. And def­i­nitely a lot of peo­ple who write exten­sions for Flash meet with spe­cific prob­lems, one of which is the mat­ter of this arti­cle. What is the prob­lem in short? If we try to cre­ate a cus­tom dia­log box, using the JSFL function,

and we want that our dia­logue has a col­or­picker with a defined by us default colour value, we see that this turns out to be impossible.

It is obvi­ous that the attribute “value” has no effect on the <col­orchip> ele­ment. How to solve this prob­lem? How to set the col­or­picker default value?

The solu­tion came to me by acci­dent, after a chain of actions caused by des­per­a­tion. Ini­tially I decided to set the col­orchip value explic­itly with the help of a defined in the dia­log javascript . I added the <script> sec­tion (where I inserted the javascript code into), as well as the oncre­ate attribute in the <col­orchip> element.

After cer­tain med­i­ta­tion, I decided that it might be nec­es­sary the javascript code to be exe­cuted with some delay, after the full ini­tial­iza­tion of the <col­orchip> ele­ment. That is why I moved the oncre­ate attribute to the next UI ele­ment in the dialog:

By good for­tune, in my spe­cific case this next UI ele­ment turned out to be a but­ton. Later I found out that the oncre­ate event does not hap­pen with the ini­tial­iza­tion of all of the UI ele­ments. Up to now I have ascer­tained that it hap­pens only when <but­ton> and <menulist> ele­ments are initialized.
