Use this constructor to create a XCoeTextDrawer object on the stack, inside your control's Draw() method. The XCoeTextDrawer object will work as a smart-pointer to the CCoeTextDrawerBase object, managing its life. Get the CCoeTextDrawerBase-derived object to use by calling CCoeControl::TextDrawer() . Do not create a new CCoeTextDrawerBase-derived object inside the Draw() method. If you want to change the text drawer used by the control or any of the control's children, override the CCoeControl::GetTextDrawer() method. Inside it you can create a new CCoeTextDrawerBase object or change the properties of the CCoeTextDrawerBase object passed to it.

An XCoeTextDrawer object should not be copied as only one handle should exist to a CCoeTextDrawer. Therefore this copy constructor is private and just contains a panic statement.

Destructor. The XCoeTextDrawer object work as a smart-pointer object to the CCoeTextDrawerBase object actually performing the text drawing. The XCoeTextDrawer object shall be allocated on the stack (i.e. not using "new") in the CCoeControl's Draw() method. Once the XCoeTextDrawer object goes out of scope, this destructor will be called. It will call Reset() on the CCoeTextDrawerBase object, if it was been set to be resuable by its owner. If not, the CCoeTextDrawerBase object will be deleted. Note that it is up to the creator/owner of the CCoeTextDrawerBase to decide whether it shall be reusable or not. A user of the XCoeTextDrawer must not change the re-use'ness of the CCoeTextDrawerBase .

Returns the text alignment that will be used by DrawText() and DrawDisplayOrderedText() . Note that left and right alignment will be swapped for right-to-left scripts, unless the alignment has been set to be absolute (see TGulAlignment ).

Return the clip rect that will be used by DrawText() and DrawDisplayOrderedText() . Any text falling outside this rectangle will not be visible. This is used to crop text.

Low level text drawing is always performed left-to-right on the screen. This means that for any script with right-to-left directionality (like Arabic), the in-memory order of the glyphs has to be changed (reordered) from the logical order (start of sentence first, before end of sentence) to the display order (end of sentence before (i.e. left of) start of sentence). This operation is performed by TBidiText .

However, sometimes text is reordered through some other means than the TBidiText class. In these cases, this method can be used to draw the text contained in a descriptor object in the same order (left-to-right) as it appears in the descriptor memory. I.e. this method assumes that the text has already been changed into the display order. If this is not the case, and the text is in a right-to-left script, it will come out backwards.

Note that the margines are relative to the orientation of the text.

Call this method to draw text contained i a TBidiText object. This is the recommended way of drawing any widget text, as it will manage both left-to-right scripts like English as well as right-to-left scripts such as Arabic and Hebrew.

Before calling this method, be sure to set the text alignment, margins, clip rect, etc using the XCoeTextDrawer methods SetAlignment() , SetMargins() , and SetClipRect() .

Note that before a TBidiText text can be drawn, it has to be line-broken using TBidiText::WrapText() with a wrap width that match the text rect minus margins.

Call this method to draw vertical text contained in a TBidiText object. This is the recommended way of drawing any widget text, as it will manage both left-to-right scripts like English as well as right-to-left scripts such as Arabic and Hebrew.

Note that before a TBidiText text can be drawn, it has to be line-broken using TBidiText::WrapText() with a wrap width that match the text rect minus margins.

Also note that the margines are relative to the orientation of the text.

XCoeTextDrawer::SetClipRect

Returns the gap (in pixels) between lines of text. Default gap is 1 (one) pixel.

Returns the text margins that will be used by DrawText() and DrawDisplayOrderedText() . Note that text effects may intrude on the margin.

Set the text alignment that will be used by DrawText() and DrawDisplayOrderedText() . Note that left and right alignment will be swapped for right-to-left scripts, unless the alignment has been set to be absolute (see TGulAlignment ).

Set the clip rect that will be used by DrawText() and DrawDisplayOrderedText() . Any text falling outside this rectangle will not be visible. This is used to crop text.

Set the gap (in pixels) between lines of text. Default gap is 1 (one) pixel.

Set the text margins that will be used by DrawText() and DrawDisplayOrderedText() . Note that text effects may intrude on the margin, and that margins are always relative to the text orientation.

This method sets the main color to use by DrawText() and DrawDisplayOrderedText() to draw text.

This method returns the main color used by by DrawText() and DrawDisplayOrderedText() .

Deprecated.

Assignment operator for CCoeTextDrawerBase objects.

Due to compiler defect/feature, this method may not work. I.e. if XCoeTextDrawer textDrawer = TextDrawer(); does not compile, restate as XCoeTextDrawer textDrawer(TextDrawer());
