As long as focus is being switched only between subcontrols of the active editor the state of the edited wxPGProperty remains unchanged and there is no need to explicitly reset the editor.
Unwanted editor resets could happen if such internal focus changes would be captured in EVT_IDLE handler.
Closes#18162.
Currently all properties within client area are processed for drawing whether they lie inside the update region or not. Processing for drawing is an expensive operation so doing this only for properties being actually repainted should improve performance.
Displaying error dialog can cause on some platforms native focus changes
what triggers unwanted focus change events in wxPG and disturbs expected
sequence of events. To prevent this from happening (regardless of platform),
we need to save focused window before dialog box is displayed and restore
it after closing the dialog.
Closes#18046.
When there is open an editor for some property and in the same time
wxPropertyGrid layout is changed (due to the adding or removing a property,
sorting), it is necessary to recalculate the actual position of the active
editor to display it in the cell dedicated for the edited property. Under
some platforms the position of the edit control is shifted within the cell
and we have to take this shift into account in repositioning process.
Because actual value of the shift depends on the platform and on
the particular control, it is convenient to determine actual shift when
the editor is created and use this value whenever repositioning is done.
Close#17912.
wxPropertyGrid::ExpandEscapeSequences() function should convert all valid
escape sequences (\r, \n, \t, \\) to the corresponding single characters
(CR, LF, TAB, backslash, accordingly) and
wxPropertyGrid::CreateEscapeSequences() function should do the reverse
operation and convert these raw characters to the corresponding escape
sequences.
Closes#17896.
Currently, customizing some dialogs for small screen environment is done statically on the build stage by setting wxPG_SMALL_SCREEN to 1 (what is done for WXWINCE only).
Instead, we can do this for all platforms in a dynamic manner, based on the classification provided by wxSystemSettings::GetScreenType() function.
In order to do so there is introduced a static helper function wxPropertyGrid::IsSmallScreen() which is used to select right parameters (size, position) for several dialogs in order to display them correctly on the small screen.
Currently, validation flags are initialized when post-process validation is invoked (in wxPropertyGrid::PerformValidation) and when first editing operation fails earlier on the pre-process validation (in wxPropertyGrid::DoEditorValidate) then these flags are not initialized and no validation error message is displayed.
Hence validation flags should be initialized in both validation functions.
