| 12 | 40 | # Multi form properties / using DataModules from other forms in the designer | |
| 13 | 41 | ||
| 14 | 42 | ## Short Description | |
| 15 | 43 | ||
| 16 | - | ||
| 44 | + | This feature allows to use components of other designer forms. A common example is to use the TDataSource on a DataModule for the DataSource property of a db control. Designer forms can only reference each other if they have a CreateForm statement in the lpr file (Project Options / Forms). | |
| 17 | 45 | ||
| 18 | 46 | ## Working | |
| 19 | 47 | ||
| 20 | - | ||

| 31 | - | ||
| 32 | - | ||
| 33 | - | ||
| 48 | + | * Manual referencing via source code works. | |
| 49 | + | * TPersistentPropertyEditor.GetValues - List all possible values. Check for class compatibility and if the target form is listed in the CreateForm statements of the lpr file and if the target unit does not belong to a package that will conflict if used. | |
| 50 | + | * TPersistentPropertyEditor.GetValue - Show component path | |
| 51 | + | * TPersistentPropertyEditor.SetValue - search the component via the given path | |
| 52 | + | * When component is deleted, the property must be set to nil - This is not the job of the IDE, but should be achieved by the normal TComponent FreeNotification feature. Maybe eventually a check could be added, if this is implemented properly and force a nil on error. | |
| 53 | + | * When a component is renamed the property does not need to be updated, because the form is open and use the pointer not the name. But the designer must be flagged 'modified', because the lfm has changed. See below. | |
| 54 | + | * When reference form is opened, then target forms are opened too. | |
| 55 | + | * When target form is closed, then only the designer is closed. The component is kept hidden. | |
| 56 | + | * When all referring forms are closed/hidden, the hidden component will be automatically freed. | |
| 57 | + | * Circle dependencies are allowed. | |
| 58 | + | * When referenced component is renamed, the using units must be set modified. | |
| 59 | + | * When referenced component is deleted, the using units must be set modified. | |
| 60 | + | * Opening a unit now checks if designer is already created | |
| 61 | + | * Reopen/Revert a form - all connected forms are now closed | |
| 34 | 62 | ||
| 35 | 63 | ## ToDo | |
| 36 | 64 | ||
| 37 | - | ||
| 65 | + | * Allow to connect to forms, that are used in the uses section. Technically there is _no_ connection between the uses section and the form streaming, because form streaming uses global variables. But the IDE must somehow find the referenced form. Without the uses section the IDE must in worst case search and read every reachable lfm file on disk. So the uses section is a good compromise between speed and flexibility. | |
| 38 | 66 | ||
| 39 | 67 | # Translations, i18n, lrt files, po files | |
| 40 | 68 | ||
| 41 | 69 | ## Short Description | |
| 42 | 70 | ||
| 43 | - | ||
| 71 | + | This feature automatically creates and updates .po files for packages and projects. | |
| 44 | 72 | ||
| 45 | 73 | ## Working | |
| 46 | 74 | ||
| 47 | - | ||
| 48 | - | ||
| 49 | - | ||
| 50 | - | ||
| 51 | - | ||
| 52 | - | ||
| 75 | + | * Dialog options for project/package to enable i18n | |
| 76 | + | * Collect TTranslateStrings from RTTI while designer form writing and writing them to lrt file. | |
| 77 | + | * Copying new strings from rst and lrt files to a single .po file for each project | |
| 78 | + | * load the .po files | |
| 79 | + | * Delete unused strings from the .po file of package/projects | |
| 80 | + | * Update translated .po files, similar to the updatepofiles tool. | |
| 53 | 81 | ||
| 54 | 82 | ## ToDo | |
| 55 | 83 | ||
| 56 | - | ||
| 57 | - | ||
| 58 | - | ||
| 84 | + | * Copying new strings from rst and lrt files to a single .po file for each package (implemented, need dialog option to change po filename or need agreedment to use same name of package) | |
| 85 | + | * Collect all .po files of project and all used packages into a directory. This directory can then be used by the project to load the strings at runtime. And installers can copy the content. | |
| 86 | + | * standardize filenames and path, so that loading the translations at runtime is possible without writing code. | |
| 59 | 87 | ||
| 60 | 88 | # Frames | |
| 61 | 89 | ||
| 62 | 90 | ## Short Description | |
| 63 | 91 | ||
| 64 | - | ||
| 92 | + | Frames are special child forms. The goal is to edit them like forms in the IDE designer, and to use them as components on designer forms. | |
| 65 | 93 | ||
| 66 | 94 | ## Working | |
| 67 | 95 | ||

| 122 | + | * show nested components in OI component tree | |
| 123 | + | * Write nested component to stream | |

| 106 | 134 | # VFI - Visual Form Inheritance | |
| 107 | 135 | ||
| 108 | 136 | ## Short Description | |
| 109 | 137 | ||
| 110 | - | ||
| 138 | + | Forms can inherit from other forms. The .lfm streams of ancestors are read/applied before the current lfm. The .lfm of the descendant is the difference between ancestor and current state. The IDE allows to open and edit inherited forms. VFI does not only apply to TForm, but TDataModule, TFrame and any registered base designer class. For the full features compile with -dEnableTFrame. | |
