delphi - Custom PropertyEditors - They never seem to appear -

information

i seem absolutely clueless how should manage component packages , install custom property editors. have spent lastly week or looking @ examples , tutorials, must doing wrong property editors never show in object inspector , require step step instructions seek , solve frustration.

component package

i have 1 package, , set designtime , runtime in options. added bundle units components (ie, mybutton, mylistbox etc) - additionally have unit containing registercomponents procedure. can build , install now, add together components new project , run them without problems.

adding custom propertyeditor

it gets tricky , confusing me want introduce property editor components bundle above.

tmybutton illustration custom button own paint methods, has published properties allow changing appearance of button - in add-on there published list allow selecting preset appearance settings, example:

tmybuttonstyle = (bsstyle1, bsstyle2, bsstyle3)

i want take away list of preset styles , instead add together property object inspector called 'presetstyles'. property of padialog, want show form can visually see different button styles - more graphical way of selecting preset style simple list.

which packages need

if understand, need split designtime packages , runtime packages?

does mean need 2 register units, 1 components , 1 property editors?

i not total sure how manage this, said current bundle designtime , runtime, not sure bundle type should split into. if create new designtime bundle property editors, , create other bundle runtime lose install button. writing confusing me.

installing propertyeditor

one of articles tried next 1 page: http://www.delphisources.ru/pages/faq/master-delphi-7/content/lib0097.html

the thing changed add together own dialog form, , alter register code from:

registerpropertyeditor(typeinfo(string), tmdsoundbutton, 'soundup', tsoundproperty);

to

registerpropertyeditor(typeinfo(string), tmybutton, 'presetstyles', tsoundproperty);

i know still says tsoundproperty, left until working alter class name.

conclusion

what right way of splitting/managing packages between actual components , design side ie propertyeditors?

the propertyeditor never appears on tmybutton in object inspector , have feeling must not configuring packages correctly or something.

i appreciate kind of assistance here, link tutorial guide or nil doing seems work, using lot of examples not working me.

i have 1 package, , set designtime , runtime in options.

to implement custom property/component editors, must separate code 2 packages - 1 runtime only bundle containing implementation code components themselves, , 1 designtime only bundle contains implementation code component registrations , custom editor(s). designtime bundle needs specify runtime package, , designide package, in requires list. runtime bundle gets compiled executables. designtime bundle ide uses components appear in component palette , form designer , interact them.

does mean need 2 register units, 1 components , 1 property editors?

no. runtime bundle should have no registrations @ all. belongs in designtime bundle instead. can have single register() function in designtime bundle registers everything.

if create new designtime bundle property editors, , create other bundle runtime lose install button.

you cannot install runtime bundle ide, designtime package.

to

does tmybutton component define presetstyles property string type? cannot define property editor property not exist.

without knowing how presetstyles property implemented in component , represents, not create much sense invoke popup dialog string property (except maybe things filenames , such). based on description, makes more sense implement component editor instead of property editor, , leave existing tmybuttonstyle property lone utilize ide's default editor enum properties. invoke popup dialog, component editor allow user right-click on component , take "edit" (or whatever other string value decide name it) popup menu, or double-click on component, in form designer. can display , edit component desired, , assign changes component when dialog closed.

the propertyeditor never appears on tmybutton in object inspector , have feeling must not configuring packages correctly or something.

it hard know sure since did not show of actual code yet.
