\S2{sectionsetflags} SectionSetFlags

|
|
|
\c section_index section_flags
|
|
|
|
Sets the section's flags. The flag is a 32 bit integer. The first bit (lowest) represents whether the section is currently selected, the second bit represents whether the section is a section group (don't modify this unless you really know what you are doing), the third bit represents whether the section is a section group end (again, don't modify), the fourth bit represents whether the section is shown in bold or not, the fifth bit represents whether the section is read-only, the sixth bit represents whether the section group is to be automatically expanded, the seventh bit is set for section groups which are partially selected, the eighth bit is internally used for partially selected section group toggling and the ninth bit is used for reflecting section name changes. The error flag will be set if an out of range section is specified.
|
|
|
|
Each flag has a name, prefixed with `SF_`:
|
|
|
|
\c !define SF_SELECTED 1
|
|
\c !define SF_SECGRP 2
|
|
\c !define SF_SECGRPEND 4
|
|
\c !define SF_BOLD 8
|
|
\c !define SF_RO 16
|
|
\c !define SF_EXPAND 32
|
|
\c !define SF_PSELECTED 64
|
|
|
|
For an example of usage please see the \L{../Examples/one-section.nsi}{one-section.nsi} example.

\S2{sectionsettext} SectionSetText
|
|
|
|
\c section_index section_text
|
|
|
|
Sets the description for the section section_index. If the text is set to "" then the section will be hidden. The error flag will be set if an out of range section is specified.
|
|
|
|
\c Section "" test_section_id

|
|
\S2{sectiongettext} SectionGetText
|
|
|
|
\c section_index user_var(output)
|
|
|
|
Stores the text description of the section section_index into the output. If the section is hidden, stores an empty string. The error flag will be set if an out of range section is specified.
|
|
|
|
\c Section test test_section_id

\S2{sectionsetinsttypes} SectionSetInstTypes
|
|
|
|
\c section_index inst_types
|
|
|
|
Sets the install types the section specified by section_index defaults to the enabled state in. Note that the section index starts with zero. Every bit of inst_types is a flag that tells if the section is in that install type or not. For example, if you have 3 install types and you want the first section to be included in install types 1 and 3, then the command should look like this:
|
|
|
|
\c SectionSetInstTypes 0 5
|
|
|
|
because the binary value for 5 is "00000101". The error flag will be set if the section index specified is out of range.
|
|
|
|
\c Section test test_section_id
|
|
\c SectionEnd
|
|
\c
|
|
\c Function .onInit
|
|
\c # associate section 'test' with installation types 3 and 4

|
|
|
|
\S2{sectiongetinsttypes} SectionGetInstTypes
|
|
|
|
\c section_index user_var(output)
|
|
|
|
Retrieves the install types flags array of a section. See above explanation about \R{sectionsetinsttypes}{SectionSetInstTypes} for a description of how to deal with the output. The error flag will be set if the section index specified is out of range.
|
|
|

\c Section test test_section_id

\c SectionEnd

\c

\S2{ssectionsetsize} SectionSetSize
|
|
|
|
\c section_index new_size
|
|
|
|
Sets the Size of the section specified by section_index. Note that the Index starts with Zero. The Value for Size must be entered in KiloByte and supports only whole numbers.
|
|
|
|
\c Section test test_section_id
|

\c FunctionEnd
|

|
\S2{ssectiongetsize} SectionGetSize
|
|
|
|
\c section_index user_var
|
|
|

|
|
|
|
\c Section test test_section_id
|
|
\c SectionEnd
|

\S2{ssetcurinsttype} SetCurInstType
|
|
|
|
\c inst_type_idx
|
|
|
|
Sets the current \R{ainsttype}{InstType}. inst_type_idx should be between 0 and 31. The Error Flag is \\<b\\>not\\</b\\> set if an out of range \R{ainsttype}{InstType} was used.
|
|
|
|
\S2{sgetcurinsttype} GetCurInstType
|
|
|
|
\c user_var
|
|
|
|
Get the current \R{ainsttype}{InstType} and stores it in user_var. If the first install type is selected, 0 will be put in user_var. If the second install type is selected, 1 will be put in user_var, and so on. The value of $\{NSIS_MAX_INST_TYPES\} (32 by default) means that the custom install type was selected.
|
|
|
|
\S2{sinsttypesettext} InstTypeSetText
|
|
|
|
\c inst_type_idx text
|
|
|
|
Sets the Text of the specified \R{ainsttype}{InstType}. If the Text is empty than the \R{ainsttype}{InstType} is removed. By using a previously unused inst_type_idx number you can create new InstTypes. To add/remove Sections to this new \R{ainsttype}{InstType} see \R{sectionsetinsttypes}{SectionSetInstTypes}. Unlike \R{ssectionin}{SectionIn} the index is zero based, which means the first install type's index is 0.
