Member Function Documentation

◆ AddFormInfo()

void TGHtml::AddFormInfo ( TGHtmlElement * p )

protected

Add the DOM control information for form elements.

Definition at line 565 of file TGHtmlForm.cxx.

◆ AddSelectOptions()

void TGHtml::AddSelectOptions	(	TGListBox *	lb,
		TGHtmlElement *	p,
		TGHtmlElement *	pEnd
	)

protected

The "p" argument points to a <select>.

This routine scans all subsequent elements (up to the next </select>) looking for <option> tags. For each option tag, it appends the corresponding entry to the "lb" listbox element.

lb – An TGListBox object p – The <SELECT> markup pEnd – The </SELECT> markup

Definition at line 303 of file TGHtmlForm.cxx.

◆ AddStyle()

void TGHtml::AddStyle ( TGHtmlElement * p )

protected

This routine adds information to the input texts that doesn't change when the display is resized or when new fonts are selected, etc.

Mostly this means adding style attributes. But other constant information (such as numbering on and images used for ) is also obtained. The key is that this routine is only called once, where the sizer and layout routines can be called many times.

This routine is called whenever the list of elements grows. The style stack is stored as part of the HTML widget so that we can always continue where we left off the last time.

In addition to adding style, this routine will invoke methods needed to acquire information about a markup. The IsVisitied() method is called for each and the GetImage() is called for each or for each that has a SRC= field.

When a markup is inserted or deleted from the token list, the style routine must be completely rerun from the beginning. So what we said above, that this routine is only run once, is not strictly true.

		TGHtmlMarkupElement *	pElem
	)

Append all the arguments of the given markup to the given TGString.

Example: If the markup is hello! then the following text is appended to the TGString:

  "src image.gif alt hello!"

Notice how all attribute names are converted to lower case. This conversion happens in the parser.

Definition at line 1407 of file TGHtmlParse.cxx.

◆ AppendBlock()

void TGHtml::AppendBlock	(	TGHtmlElement *	pToken,
		TGHtmlBlock *	pBlock
	)

protected

Append a block to the block list and insert the block into the element list immediately prior to the element given.

Definition at line 1613 of file TGHtml.cxx.

◆ ComputeVirtualSize()

void TGHtml::ComputeVirtualSize ( )

protected

Computes virtual size of html area.

Definition at line 508 of file TGHtml.cxx.

◆ ControlSize()

int TGHtml::ControlSize ( TGHtmlInput * pElem )

protected

This routine implements the Sizer() function for <INPUT>, <SELECT> and <TEXTAREA> markup.

A side effect of sizing these markups is that widgets are created to represent the corresponding input controls.

The function normally returns 0. But if it is dealing with a <SELECT> or <TEXTAREA> that is incomplete, 1 is returned. In that case, the sizer will be called again at some point in the future when more information is available.

Definition at line 357 of file TGHtmlForm.cxx.

  N.M          Token number N (with numbering starting at 1) and
               character number M (with numbering starting at 0).

  M.X          Like above, but token is markup and X is an attribute.

  begin        The start of all text

  end          The end of all text

  N.last       Last character of token number N.

  N.end        One past last character of token number N.

  sel.first    First character of the selection.

  sel.last     Last character of the selection.

  sel.end      On past last character of the selection.

  insert       The character holding the insertion cursor.

  @X,Y         The character a location X,Y of the clipping window.

  &DOM         The DOM Address of a token.

Zero is returned if we are successful and non-zero if there is any kind of error.

If the given token doesn't exist (for example if there are only 10 tokens and 11.5 is requested) then *ppToken is left pointing to NULL. But the function still returns 0 for success.

protected

'frame' is the child widget that is used to implement an input element.

Query the widget for its size and put that information in the pElem structure that represents the input.

Definition at line 192 of file TGHtmlForm.cxx.

◆ Sizer()

void TGHtml::Sizer ( )

protected

Compute the size of all elements in the widget.

Assume that a style has already been assigned to all elements.

Some of the elements might have already been sized. Refer to the fLastSized and only compute sizes for elements that follow this one. If fLastSized is 0, then size everything.

This routine only computes the sizes of individual elements. The size of aggregate elements (like tables) are computed separately.

The HTML_Visible flag is also set on every element that results in ink on the page.

This routine may invoke a callback procedure which could delete the HTML widget.

Definition at line 1076 of file TGHtmlSizer.cxx.

The min and max size for column N (where the leftmost column has N==1) is pStart->fMinW[1] and pStart->fMaxW[1]. The pStart->fMinW[0] and pStart->fMaxW[0] entries contain the minimum and maximum widths of the whole table, including any cell padding, cell spacing, border width and "hspace". The values of pStart->fMinW[I] for I>=1 do not contain any cell padding, cell spacing or border width. Only pStart->fMinW[0] contains these extra spaces.

The back references from

◆ TableText()

TGString * TGHtml::TableText	(	TGHtmlTable *	pTable,
		int	flag
	)

Return text and images from a table as lists.

The first list is a list of rows (which is a list of cells). An optional second list is a list of images: row col charoffset tokenid. Note: weve added the option to store data/attrs in array var directly.

flag - include images

◆ TokenByIndex()

TGHtmlElement * TGHtml::TokenByIndex	(	int	N,
		int	flag
	)

protected

Return a pointer to the Nth TGHtmlElement in the list.

If there is no Nth element, return 0 if flag==0 and return either the first or last element (whichever is closest) if flag!=0

Definition at line 48 of file TGHtmlIndex.cxx.

◆ Tokenize()

int TGHtml::Tokenize ( )

protected

Process as much of the input HTML as possible.

Construct new TGHtmlElement objects and appended them to the list. Return the number of characters actually processed.

This routine may invoke a callback procedure which could delete the HTML widget.

This routine is not reentrant for the same HTML widget. To prevent reentrancy (during a callback), the p->fICol field is set to a negative number. This is a flag to future invocations not to reentry this routine. The p->fICol field is restored before exiting, of course.

Definition at line 563 of file TGHtmlParse.cxx.
